Element miner

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. Bonus 99 friends, the average person does not have much money.

3. The equipment list for molybdenum ore dressing is determined according to the molybdenum ore dressing process, and the equipment selected for different molybdenum ore dressing processes are also different
the equipment used in molybdenum flotation process of Yixing mine are:
two crushers, which are used for coarse crushing and fine crushing respectively
one feeder for coarse crushing
several belt conveyors: depending on the layout of the plant area
one ball mill
one classifier is used together with the ball mill
several cells of the flotation machine, depending on the flotation process requirements
a number of stirred tanks, depending on the flotation process requirements< The number of sand pumps depends on the equipment configuration
one thickener and one filter. If it's simple, it can be replaced by other methods
the above is the main process equipment, other equipment depends on the requirements of the main equipment, can not be generalized
in addition, the selection of equipment varies greatly, which depends on the process and preparation requirements.

4. After purchasing the miner with Amoy elements, the spent Amoy elements will be automatically destroyed by the system, and the indivial does not need to operate anything.

Each row in a relational table is called a tuple

Every element (D1, D2,..., DN) in Cartesian proct is called an n-tuple or a tuple for short. When the relationship is a table, each row in the table (that is, each record in the database) is a tuple, and each column is an attribute. In a two-dimensional table, tuples are also called records

extended data :

each column in a data table is called a field. A table is defined by various fields it contains. Each field describes the meaning of the data it contains. The design of a data table is actually the design of a field

when creating a data table, assign a data type to each field and define their data length and other attributes. Fields can contain a variety of characters, numbers, and even graphics. If wrong! Reference source not found

6. Yes, you can drink it directly. There are many micro elements in the water filtered by the water quality miner. Drinking it is also good for the human body. You can also lose weight and dredge blood vessels

7. The most wear-resistant is Mn. Wear resistant steel Mn13. And zg40simn are used in excavators, excavators and mining machines, all of which contain Mn. Is an essential element!

Gold and silver are rare and precious metal elements, which belong to associated type in massive sulfide deposits and are the main comprehensive utilization objects of associated elements. Their distribution in the lithosphere is very small, because they have special economic value and are easy to be mined, beneficiated and smelted. Even though they are far lower than the main metal elements Cu, Pb and Zn (such as Xiaotieshan deposit), they also include gold and silver as the main metal elements, and even affect the attribution and naming of the original deposit types. According to the analysis of geochemical properties of elements, Au, Ag, Cu, Zn, Pb and other elements belong to the same copper affine element (sub group) and have the same outer electron layer (18) structure, forming stable sulfide in the crust. In the thermal fluid, they migrate in the form of complexes; When the concentration of oxygen in the medium is high and fluorine and chlorine exist, it is stable; When the concentration of S, Se, Te, < inline media object > < imageobject > < imagedata role = "3" fileref =. / image / figure-0114-01.

Due to the high ionization potential, it is difficult to release electrons, and tends to generate natural elements (AU, Ag, Cu, etc.). Gold and silver in massive sulfide ore

is realized in the process of exhalative volcanic sulfide mineralization on the background of chalcophile (sulfur) element geochemical field. However, e to the different positions of gold, silver, copper, zinc and lead in the periodic table, the multi-stage metallogenic characteristics of re dispersion and re enrichment may occur. Xiaotieshan has such characteristics, which can be taken as an example

According to sun Peiji and Wei Yongfu's (1996) discussion on the main types, ore controlling conditions and ore deposit models of gold deposits in volcanic rock areas, combined with the types, ore controlling conditions and metallogenic mechanism of gold deposits in marine volcanic rock distribution areas of North Qilian Mountains, the following discussion is made

According to the physicochemical characteristics of ore-forming fluids in different types of gold deposits, four types of physicochemical assemblages can be roughly divided, and the combination of each type of physicochemical conditions is favorable for the precipitation of one or several types of gold deposits

(1) if the fluid's < inline media object > < imageobject > < imagedata role = "3" fileref =. / image / figure-0115-01. JPG > < title > < / Title >

(4) the logarithm of oxygen fugacity is - 27 ～ - 22 in the temperature range of 450 ～ 300 ℃

there are many massive sulfide deposits (spots) in the North Qilian Mountains, mainly distributed in the acid volcanic dome (short anticline) area of Baiyinchang and guomisi areas, and the gold associated with polymetallic sulfide mineralization also has the similar physical and chemical conditions mentioned above. Similar to group (3) above, this syngenetic condition can also be called the stage enrichment of gold.

. For example, xishanliang gold ore in xialiugou is pyrophyllite and kaolinite assemblage containing fine pyrite, which shows low temperature alteration characteristics of superimposed transformation and enrichment in the later stage

According to the comparison of the main tectonic altered rock type gold deposits in China (table 59), there are similarities and differences in the metallogenic background, deposit characteristics and metallogenic conditions of various types of tectonic altered rock type gold deposits. However, the ctile brittle shear structure plays a dominant role. In particular, the Kangguer gold deposit of the late Paleozoic fold system and the LAOWANGZHAI ophiolitic hybrid gold deposit of the Sanjiang fold system in the eastern Tianshan Mountains are similar to the gold deposits in the volcanic rock area in the study area (Fig. 5-40-fig. 544). According to Pei Rongfu et al., 1995, the characteristics of typical tectonic altered rock type gold deposits in China are compared from table 5-9 to table 5-9; Zeng zhangren et al., 1996; Sun Peiji et al., 1996

according to the investigation in the pressure column, the metallogenic temperature range of the Kanggur altered mylonite type gold deposit is 140-310 ℃, and the common value range is 200-260 ℃. It belongs to the middle low temperature hydrothermal metallogenic proct. Jiaojia gold deposit in Shandong Province (200-280 ℃), Shangguan gold deposit in Henan Province (180-300 ℃), Hetai gold deposit in Guangdong Province (125-600 ℃), Xiaoqinling gold deposit (155-303 ℃), LAOWANGZHAI GOLD DEPOSIT, although there are no temperature and pressure data, the ore-forming temperature will not be high based on ore Association and altered rock type. According to the comparison of characteristics, it can be inferred that the metallogenic temperature of gold deposits in the tectonic altered rocks in the study area should still be of medium low temperature hydrothermal type

under the multi-stage mineralization process of gold deposits, the "three multi" characteristics of ore-forming materials, mixed hydrothermal solution from metamorphic water, magmatic water and Tianshui and multi genesis of ore-forming types are more obvious. In addition to the syngenetic or synchronous mineralization of the associated gold deposits, the tectonic altered gold deposits are characterized by late superimposition and transformation

because the results of stable isotope test are not available, the genesis of gold deposits in the study area can not be accurately judged, so the characteristics of the same type of gold deposits mentioned above are compared in order to obtain evidence in the study of gold deposits in the study area
