in 1996, 214.97 million tons of iron ores were selected, accounting for 85.2% of 252.28 million tons of raw iron ores in China. Iron ore is selected to proce 85.857 million tons of iron concentrate powder, including 109.61 million tons of raw ore processed by key concentrators and 41.58 million tons of iron concentrate powder proced, accounting for 48.4% of China's iron concentrate powder output< (1) ore crushing
in China, the three-stage crushing process of coarse crushing, medium crushing and fine crushing is generally used to crush iron ore. Generally, 1.2m or 1.5m rotary crusher is used for coarse crushing, 2.1m or 2.2m standard cone crusher is used for medium crushing, and 2.1m or 2.2m short head cone crusher is used for fine crushing. After coarse crushing, the ore is not more than 1m in size, and then it is crushed by medium and fine crushing. The final proct with ore particle size less than 12mm is sent to the grinding tank< (2) grinding process
in China, most iron ore grinding processes adopt two-stage grinding process, and most small and medium-sized concentrators adopt one-stage grinding process. Due to the new process of fine screen regrinding, some concentrators have changed from two-stage grinding to three-stage grinding in recent years. Generally, the grinding equipment used is relatively small, and the maximum ball mill is 3.6m × 6m, maximum rod mill 3.2m × 4.5m, maximum autogenous mill 5.5m × 1.8m, gravel mill 2.7m × 3.6m
spiral classifier is basically used for classification after grinding. In order to improve the efficiency, some concentrators use hydrocyclone instead of secondary spiral classifier< (3) beneficiation technology
1. Beneficiation of magnetite is mainly used to beneficiate low-grade "Anshan type" magnetite. Due to the strong magnetism and good grinding and separation of ores, domestic magnetic separation plants all adopt stage grinding and multi-stage grinding processes. For coarse-grained magnetite, the former (primary grinding) is adopted, while for fine-grained and fine-grained magnetite, the latter (secondary or tertiary grinding) is adopted. A series of permanent magnetic separators developed by our country have realized permanent magnetization. After the 1970s, the new technology of fine screening and regrinding was popularized in the national magnetite concentrators, so that the concentrate grade was increased from 62% to 66%, which met the requirement of 65% put forward by the Ministry of metallurgical instry
2. Beneficiation of weak magnetic iron ore
is mainly used to separate hematite, limonite, Specularite, siderite, pseudo hematite or mixed ore, that is, the so-called "red ore". This kind of ore has low grade, fine disseminated grain size, complex mineral composition and difficult separation. Since the 1980s, the research on roasting magnetic separation, wet high intensity magnetic separation, weak magnetic flotation and gravity separation process, equipment and new kinds of reagents have been continuously improved, resulting in the continuous improvement of concentrate grade and metal recovery. For example, Qidashan concentrator of Anshan Iron and Steel Co. has adopted a new process flow of weak magnetic, strong magnetic and flotation, which has made encouraging achievements
3. Beneficiation of polymetallic syngenetic ore
this kind of ore has complex composition and various types, so the methods, equipment and processes used are also different, such as reverse flotation multi gradient magnetic separation, flocculation flotation, low intensity magnetic reverse flotation high intensity magnetic separation, low intensity magnetic positive flotation, roasting magnetic separation and other different processes used in Bayan Obo iron mine to improve the iron recovery, And comprehensive recovery of rare earth oxide. Panhua Iron Mine obtains about 53% TFE ferrovanadium concentrate by magnetic separation, and the tailings after magnetic separation obtain titanium concentrate and sulfur cobalt concentrate by low intensity magnetic scavenging high intensity magnetic separation gravity separation flotation dry electric separation, so as to recover titanium and cobalt. Iron, copper, cobalt, sulfur and other elements are comprehensively recovered in Daye Iron Mine by weak magnetic high magnetic and flotation< (4) sinter pellet technology
sinter technology is the main means of man-made rich ore in China. In 1996, a total of 160.956 million tons of man-made rich ores were proced, including 94.859 million tons of key enterprises, accounting for 58.9%, and 61.337 million tons of local state-owned enterprises, accounting for 38.1%
China's fine concentrate sintering technology has reached a considerable level. As early as the early 1950s, Anshan Iron and steel company successfully changed the proction method of acid sinter to that of alkaline sinter on the sintering machine. It was the first in the world to use hydrated lime or quicklime as flux to solve the problem of fine concentrate sintering< There are 419 sintering machines in China, with a total area of 15522m2, among which there are 22 sintering machines above 130m2, with a total area of 4107m2; 197 sintering machines of 24-129m2, with a total area of 9387m2; There are 200 sintering machines less than 24m2, with a total area of 2028m2. The 300m2 sintering machine, which was put into operation in Maanshan Iron and steel works on February 24, 1994, is the largest modern sintering machine designed, manufactured and built by ourselves except Baosteel
the main technical and economic indexes of sintering in China in 1995 are as follows: utilization coefficient 1.36t / (M2? h) The sinter grade is 53.00%, the calendar operation rate of sinter machine is 80.94%, the qualified rate of sinter is 84.92%, and the labor proctivity is 2170t / (H? A)

7. The full name of "mineral powder" used in concrete is ground water quenched granulated blast furnace slag powder. Slag comes from the slag discharged from the blast furnace ring ironmaking in the iron and steel plant. It is sprayed with water and cooled rapidly to form granular slag. Then it is dried and ground to obtain ground slag powder, namely "ore powder". The price of mineral powder is generally lower than that of cement, but for places far away from resources (steel plants), the price may also be higher than that of cement e to the high freight cost
mineral powder is now widely used in concrete, in addition to the use of instrial waste slag, which has better environmental protection and social benefits, mineral powder can also improve some physical and mechanical properties of concrete, especially the impermeability and rability of concrete. Therefore, many infrastructure projects, such as bridges, wharves, high-speed rail, etc., require the use of mineral powder in concrete (accounting for 30% ~ 60% of cementitious materials). In addition, the ultra-fine grinding mineral powder (specific surface area 5000 ~ 8000) can significantly improve the strength of concrete
however, ordinary fine mineral powder (about 3000) has poor water retention, which will increase the bleeding of concrete and rece the early strength of concrete.

8. Recently, Lei Pingxi, executive vice president of China Association of metallurgical and mining enterprises, predicted the iron ore market in 2015 when attending a meeting. He predicted that the average CIF price of 62% mineral powder in 2015 will be about 92 US dollars / ton, which is about 10% lower than the average price in 2014< According to Lei Pingxi's analysis, the global crude steel consumption is expected to decline in 2015, and the growth rate of crude steel output is slightly lower than that in 2014, with an annual growth rate of about 2.4%; China's crude steel consumption continues to increase slightly or decrease slightly, and its output growth is lower than that of 2014, and also lower than the global level. It is estimated that the annual growth will be about 1.7%. The contradiction of oversupply in the steel market is still prominent, the rebound of steel prices is limited, the funds of enterprises continue to be tight, the market competition is more fierce, and the adjustment of proction capacity is imperative
he believes that 2015 is still a period of rapid release of proction capacity of the four major mining companies, the world iron ore export will grow by more than 7%, and the trend of short-term market oversupply will continue to expand. Due to the poor resource endowment, low operation efficiency and high proction cost of domestic iron ore enterprises, a number of small and medium-sized mines will stop proction and close down. Domestic mines will decline in 2015, and the decline is expected to be about 10%
in addition, Lei Pingxi also said that the price of iron ore has dropped significantly, which reces the cost of imported iron ore in the short term and is concive to easing the operating pressure of iron and steel enterprises; However, in the medium and long term, low ore price will lead to financing difficulties, investment decline and scale shrinkage of domestic iron ore exploration and development projects, which is not concive to the stable development of domestic iron ore enterprises; The major international mining companies choose to increase proction, expand, and constantly increase the supply of iron ore. The import of iron ore has increased significantly, and the degree of dependence on foreign countries continues to rise. As a result, China's iron ore resources become more tightly constrained, and the contradiction between resources and security becomes more prominent, which will have a more significant impact on China's iron and steel instry and economic security
the continuous decline of iron ore prices is not concive to the cost recovery of overseas mine investment. At present, the overseas investment of iron ore in China is generally at a high price. The construction period is prolonged and the investment overrun is prominent. Due to the decline of ore price, the future proction capacity will not be able to achieve the expected market income, which will increase the pressure on the capital chain of investment enterprises. It may even lead to that they can not bear the impact of the price drop and are purchased by large international mining enterprises at a low price< In the end, he also pointed out that the current cliff like decline in iron ore prices is influenced by market supply and demand fundamentals, but it is not simply an accurate reflection of the relationship between supply and demand, let alone a "reasonable price in the market" when the price falls below US $80 / T. The influence of factors such as oligopoly and speculation has not weakened, but has continued to increase, The future trend of iron ore price is not only a single downward path, but also a comprehensive embodiment of the game between "mine" and "steel" under the new situation, which depends on the business strategy of mining giants and the supply guarantee strategy of China's iron ore resources.

10. I am the material director of the engineering unit. I can give you some suggestions for reference
1 the average driver of a loader with good technology is about 35 tons per car in 10 minutes, and it will take 5 hours for 1000 tons, but it can't be stopped. Because the vehicle needs to move, it takes 7-8 hours. If the fuel consumption is low, the 50 loader with good engine condition has 100 liters of diesel oil. The loading of my quarry is outsourced, 1 yuan / ton
2 the problem of how much electricity the belt conveyor uses is very simple. You can see from the power of the motor. Isn't it? No matter whether it's empty or carrying stones, it's not the accelerator, so the power consumption difference is not big. As for belt replacement, if it is used correctly and maintained properly, it will not need to be replaced for a month. As long as it is not hung and pulled off, 100000 tons of materials will not need to be replaced
3 it's the same with how much electricity the crane uses. If the crane uses 1.2 yuan / ton of stone, the profit will be good. Of course, it needs the cooperation of good drivers and clearance personnel.
