Aluminum ore screening machine

1. Hello! First of all, what kind of process do you adapt to? Therefore, it is necessary to make spectrum of the ore first, then make quantitative analysis of the corresponding valuable elements according to the spectrum analysis results, and then do beneficiation test. According to the mineral processing test, calculate the output value, mining, beneficiation and smelting cost, and calculate the profit margin of instrial proction. At this time, the equipment can be determined according to the technological process selected by the beneficiation test. The equipment must not be determined according to the experience, the suggestions of a single technician or the suggestions of the equipment factory without test basis. Too many factories built like this stop there, causing heavy losses!

2. MLM has zero cost, and the blockchain needs to be mined

MLM is a pyramid structure, blockchain is indivial centered, MLM is a crime, and blockchain can be used in technology

3. Eccentric wheel is mainly to change circular motion into linear reciprocating motion
mainly used in press and screen machine! Such as a series of driving force is circular motion, and the actual need is a reciprocating linear motion of machinery
let's talk about the above two kinds of machines:
the press changes the circular motion of the inertia wheel driven by the motor into the up and down movement of the die punch! To meet the needs of stamping
the purpose of ore screening is to change the circular motion of the motor into the forward and backward movement of the screen!

4. There should be, but Anshan mining machinery is sure to proce all kinds of vibrating screen.

bauxite is a kind of mineral, which is composed of diaspore, boehmite, gibbsite, etc. Our country is mainly based on diaspore, Australia's mining is better, diaspore is the main, ha ha, off topic
bauxite for brown corunm proction, also called bauxite, is actually sintered bauxite, mainly to improve the aluminum content, remove impurities, moisture and so on
brown corunm is obtained by smelting bauxite, and other raw materials need to be added, mainly anthracite, scrap iron, electric arc furnace, 2500 degree smelting, and then after cooling and sorting, it becomes what you call brown corunm block. The above steps are all the business of smelters and mines, and it is estimated that there is no smelting part when you enter the first level block
the next step is the crushing and screening of brown corunm blocks. These are not complicated, but purely physical processes. Large pieces are broken into small pieces, and small pieces are made into sand by ball mill or bamak or other crushing equipment. After rough screening, magnetic separation and fine screening... And so on, divided into different particle size, 24, 3036, 1802, 220240, this process is almost the same, each factory is similar
the main uses are refractories and abrasives. Of course, there are content requirements, mainly the content of alumina, iron oxide, titanium oxide, magnesium oxide and calcium oxide.
there are many inspection standards for brown corunm, one is chemical composition, that is, the content mentioned above, one is particle size composition, the other is magnetic content, which is also very important, And bulk density
as for iron powder, st removal powder, magnetized iron sand and unmagnetized iron sand, they are all proced in the proction process of brown corunm sand, which can be regarded as by-procts, or impurities, which are also very valuable!!! Don't underestimate it. If you do a good job, you can make more profits than the main procts.
that's about it. Peers need to communicate frequently

6. We wash mud - Screening - magnetic separation - flotation - re wash mud - add medicine to improve whiteness, the proct is OK. Need to adjust the process according to your actual situation
oh. It can be calcined.

The physical geological data collected by the national physical geological data center is the most important physical geological data in China. The definition principle is: it should be typical, representative, special and systematic, and can reflect the geological conditions and metallogenic characteristics of China in a certain way. According to this principle, the selection of mineral physical geological data should be comprehensively considered from the aspects of mineral type, deposit scale, genetic type and metallogenic zone. The preliminary selection basis of mineral physical geological data is as follows

According to incomplete statistics, 172 kinds of minerals have been found in China. The collection work of the national physical geological data center should be guided by the needs of the country, and provide public welfare services for the country's economic construction. The collected data should be able to show the national metallogenic geological characteristics and major work achievements made by the important work deployment. Therefore, the national physical geological data center takes domestic important minerals as the first choice, including dominant minerals, strategic minerals and minerals of great significance to national economic construction

There are 22 kinds of important metal minerals: iron, copper, lead, zinc, cobalt, nickel, tungsten, molybdenum, bismuth, antimony, mercury, tin, chromium, vanadium, titanium, manganese, gold, silver, rare earth metals, rare metals, aluminum and magnesium; There are 20 kinds of important non-metallic minerals: magnesite, fluorite, refractory clay, pyrite, mirabilite, barite, natural alkali, halite, potash, boron, strontium, phosphorus, diamond, graphite, talc, gypsum, cement limestone, siliceous raw materials, kaolin and bentonite; Important energy minerals mainly include oil, natural gas and coal mines After the promulgation of the decision of the State Council on strengthening geological work, China will further strengthen the exploration of oil, natural gas, coal, coalbed methane, uranium, iron, copper, aluminum, lead, zinc, manganese, nickel, tungsten, tin, potash and gold, among which seven minerals, namely oil, natural gas, coal, uranium, iron, copper and aluminum, are particularly prominent

among the key minerals, the physical geological data of oil, natural gas and radioactive minerals are directly entrusted by the Ministry of land and resources to be kept by the data generating unit. Therefore, the national physical geological data center mainly collects the physical geological data of metal and non-metal types, with the focus on iron, copper, aluminum, lead, zinc, manganese, nickel, tungsten, tin, gold, rare earth metals, rare metals, etc The physical geological data of potash, as well as the physical data of oil, coal, oil shale, shale gas and other energy minerals

2. Physical geological data of large and super large deposits

considering the scale of deposits, we should focus on collecting physical geological data of super large deposits and large deposits, and selectively collect physical geological data of medium-sized deposits with special significance

at present, there is no universally accepted standard for the classification of superlarge deposits. In this paper, according to Tu Guangchi's book "super large deposits in China (I)", deposits with reserves more than five times of the standard reserves of large deposits are called super large deposits. The scale of ore deposits is divided according to the standard published by China mineral reserves Commission in 1987

Pei Rongfu, a geologist of mineral deposits, pointed out that superlarge mineral deposits are those with extremely large mineral reserves and special metallogenic characteristics, which only account for 7% - 10% of the total number of deposits, but can solve 70% - 90% of the global mineral resources of this kind of mineral, which has great economic value and strategic significance

Although the number of large and super large deposits is small, the mineral reserves and economic value are huge. Large and superlarge deposits are often the proct of multiple metallogenic and ore controlling factors. They have unique and complex genesis and formation conditions. Their physical and geological data conform to the general principle of typicality and representativeness. The development and utilization of these physical geological data is concive to the study of large and superlarge deposits, and is of great significance to reveal the metallogenic law of deposits It is very important to develop the theory of ore genesis. Therefore, it is necessary to collect the physical geological data of large and super large deposits

3. Representative physical geological data of main genetic type deposits of important minerals

considering the genetic type of deposits and the comprehensiveness of collection, typical deposits of each genetic type of important minerals are the objects of physical geological database collection. A mineral may have different genetic types of deposits, which may be dominated by one or several genetic types, followed by other genetic types. In the screening, the main genetic type of ore deposits should be selected as the main screening object, and a small number of other genetic types should be selected, so as to achieve clear primary and secondary, complement each other and comprehensive screening

For example, copper deposits can be divided into several genetic types. Porphyry copper deposits are the most important copper deposits in China, with proven reserves accounting for 42% of the total reserves; The second is skarn type copper deposit, with proven reserves accounting for 26% of the total reserves. Therefore, in the selection of copper deposits, we should give priority to these two genetic types and give consideration to other genetic types. The most typical and representative physical geological data of each genetic type should be screened out

Physical geological data of ore deposits formed in the main metallogenic ages of important minerals. From the point of view of some single mineral types, although the span of time distribution is also large, the number of deposits formed in different periods is very uneven. For example, according to Guo Wenkui's statistical analysis of the metallogenic ages of 544 major endogenetic metal deposits in China, 55% of them were formed in Mesozoic era; Most nonferrous metal deposits are formed in Mesozoic era; Iron ores are mainly distributed in Archaean Proterozoic strata

Therefore, when selecting and collecting the physical geological data of the deposit, we should fully consider the relationship between the mineral type and the main metallogenic age, focus on collecting the physical geological data of the deposit formed in the main metallogenic age of the mineral type, and supplement the physical geological data of the secondary metallogenic age

Physical geological data of representative deposits in different metallogenic belts

China has a vast territory and is located at the intersection of Eurasian plate, Pacific plate and Indian plate. The strata of different ages are well-developed, the structures are complex and changeable, and the magmatic activities are intense and multi-stage, resulting in rich mineral resources. However, the types of ore deposits, the combination of ore-forming elements, the spatial distribution characteristics of ore deposits and the intensity of different metallogenic ages are different in different tectonic domains, and there are some regular internal relations between them. In the process of screening the physical geological data of mineral resources, it is necessary to fully combine the division of the mining area belt, and focus on screening the most representative physical geological data of mineral deposits in the specific metallogenic zone. For example, in the copper iron gold metallogenic belt in the middle and lower reaches of the Yangtze River, the main minerals are copper, iron, gold and sulfur, the main genetic types are contact metasomatic type and continental volcanic intrusive rock type, and the main metallogenic age is Yanshanian. Through such a series of locking, Daye iron deposit, Tonglushan Copper Deposit, Dongguashan copper deposit, Meishan Iron Deposit and other representative deposits are selected in the middle and lower Yangtze River metallogenic belt

Other physical geological data of deposits with important and special significance mainly include deposits with important and special genetic, instrial, economic and Mineralogical Significance, deposits of great significance in the history of mining development, deposits of new deposit types, deposits of new mineral types or some non-traditional mineral resources. This kind of physical geological data is also collected by the national physical geological data center

For example, the Shilu iron deposit in Hainan is an important iron rich ore procing area in China; Tongkuangyu Copper Deposit is the oldest porphyry copper deposit in China; Shifang phosphate deposit in Sichuan Province, formed in the Middle Devonian, contains not only fluoroapatite, but also strontium aluminophosphate with instrial value. Its metallogenic age and ore composition are rare in the world; The Donghai Muscovite deposit in Jiangsu Province is the only instrial mg Si Muscovite deposit at home and abroad; Xingzi kaolin deposit is the main raw material of Jingdezhen ceramics; Tongguanshan Copper Mine in Anhui Province and Baiyinchang copper mine in Gansu Province have a long history of mining, and played an important role in national construction in the early days of the founding of new China

It is a new understanding of geologists that new types of ore deposits and new types of ore deposits. This new understanding often plays an inestimable role in enriching metallogenic theory, developing and utilizing mineral resources and studying mineralogy. For example, Dongping gold deposit in Hebei Province is the first new deposit type in China, which occurs in alkaline complex. Its discovery and development will make the gold deposit related to alkaline rock one of the important instrial deposit types of gold resources in China, and open up a new field of gold prospecting and theoretical research in China; Dashuigou tellurium bismuth gold deposit in Shimian County, Sichuan Province is the first independent tellurium deposit in the world. In the past, it was thought that tellurium element could not form a deposit of instrial significance. The discovery of Dashuigou independent tellurium deposit is a breakthrough in the past

new mineral types, such as gas hydrate; Non traditional mineral resources, such as metallic ooze, polymetallic noles, sulfide deposits, etc; Another example is the cesium bearing sillimanite and Quanhua body in Zabuye salt area, Tibet, and the stibnite mineralization in Yangbajing Geothermal field, Tibet. Such objects should also include those obtained from the investigation and study of polar mineral resources

With the development of economy, the demand for mineral resources is increasingly strong, and it is inevitable to make full use of domestic and foreign mineral resources. Through risk exploration and international exchange, the collection of overseas mineral physical geological data is an important aspect of physical geological data screening and collection. The key points collected by the national physical geological data center are as follows: first, deposits in countries or regions with the same metallogenic environment as China, which have analogical relationship with some deposits in China; The second is the genetic type of deposits peculiar to foreign countries but not developed in China; The third is the physical geological data of foreign mineral resources exploration projects that have made great achievements

9. It is said that Napoleon III's knives and forks were made of aluminum. At the banquet, he provided gold tableware for most of the guests, while only a few of them used aluminum tableware, in order to impress the guests who used aluminum tableware. In 1885, the top cap of the Washington Monument, which was completed in Washington, D.C., was also made of aluminum. Because in the 19th century, aluminum was a precious metal. The aluminum grain that people get at first is like a treasure, and its price is equal to that of gold. Because it's extremely difficult to extract aluminum from aluminum ore. In 1825, a small amount of pure aluminum was separated in Auster, Denmark. In 1827, Weiler, a German chemist, reacted metal potassium with anhydrous aluminum chloride to proce aluminum. But potassium is too expensive to be proced on a large scale. Another 27 years later, the French chemist de vill used sodium metal and anhydrous aluminum chloride to heat together to obtain small aluminum balls with metallic luster. Although the proction cost of aluminum is greatly reced by using sodium metal, it is obviously not up to the level that people can widely use aluminum. In 1884, in the Department of chemistry at Oberlin College, there was a young student named Charles Martin hall. He was only twenty-one at the time. Once, he heard a professor (who was a student of Weiler's) say: "Whoever can invent a low-cost aluminum smelting method will be outstanding." This makes hall realize that only by exploring cheap methods of aluminum smelting can aluminum be widely used. Hall decided to set up a family laboratory in his family's firewood room. He plans to apply one of David's early inventions: to pass an electric current into a molten metal salt, metal ions can be deposited on the cathode, so that the metal ions can be separated. Because the melting point of alumina is very high (2050 ℃), he had to find a material that could dissolve alumina and rece its melting point. He accidentally found cryolite (Na3AlF6). The melting point of cryolite alumina molten salt is only between 930 ℃ and 1000 ℃. Cryolite does not decompose at electrolysis temperature and has enough fluidity. This is concive to the electrolysis. Hall used porcelain crucible, carbon rod (anode) and self-made battery to electrolyze the refined alumina ore. When alumina is dissolved in 10% ～ 15% molten cryolite and current is applied, bubbles are observed, but no aluminum is precipitated. He speculated that the current caused the silicon dioxide in the crucible to decompose, thus freeing silicon. So he modified the battery, using carbon as the lining of the crucible and carbon as the cathode, thus solving this problem. One day in February 1886, he finally saw small spheres of aluminum gathering on the cathode. Hall was very excited at this time and went to see his professor with a metal aluminum ball he got for the first time. Later, these aluminum balls became "crown jewels" and still exist in the exhibition halls of American aluminum companies. With the invention of cheap aluminum smelting method, aluminum, which accounts for 8% of the earth's crust, has become an important material for human beings. Hall, the inventor, was less than 23 years old at that time, and his 23rd birthday was on December 6 of this year. It is also worth mentioning that a young French chemist of the same age as hall, ERU, invented the same aluminum smelting method later this year
hall and ELU came to the world in 1863 and invented electrolytic aluminum smelting in 1886. Although there was once a patent dispute between them, they became intimate friends later. In 1911, when the American Chemical Instry Association awarded hall the famous peqin medal, ERU went all the way to the United States to participate in the award ceremony and personally congratulated hall. Perhaps it was God's will that in 1914, the two scientists died one after another. No wonder people always associate the names of hall and ELU when they mention electrolytic aluminum smelting.
