Xinjiang steel companies reduce ore processing costs through new production lines

At the beginning of 2015, the iron ore industry was greatly affected. A series of problems such as the sharp drop in iron ore prices and serious losses affected the development of mining enterprises. China's Ministry of Mines and iron miners are all trying to improve this situation. The sharp drop in iron ore prices has led to serious losses for iron ore companies. Reducing the cost of iron ore processing has become the only way for steel companies and iron ore companies to turn losses into profits. Xinjiang, as a major mineral resource province, has abundant iron ore resources. In order to reduce the cost of iron ore processing, Xinjiang steel companies have introduced new iron ore processing production lines. At present, the new iron ore processing production lines of many steel companies in Xinjiang have been put into operation and have achieved satisfactory results.

Before this, the iron ore processing production lines of Xinjiang steel companies, including Hegang, Yigang and other large steel companies, were mainly strong magnetic separation production lines and magnetized roasting production lines, all of which were aimed at weak magnetic hematite. This iron ore processing production line not only has a large investment in equipment, high production costs, but also caused a certain amount of pollution to the environment, and the beneficiation index has never reached the ideal level. Affected by the plummet of iron ore prices, the iron ore processing project of Xinjiang Steel Enterprise The losses are serious. In order to improve this situation, Xinjiang steel companies need an energy-saving, environmentally friendly, and efficient Xinjiang iron ore processing production line. Through various channels, they have learned that Furui Machinery has in-depth research and unique insights on iron ore processing. Both Xinjiang Yili Steel Plant and Hejing Steel Plant sent technicians to Forui Machinery for inspection and discussion, and provided ore samples for beneficiation tests. Based on the properties of Xinjiang iron ore, Forui Machinery conducted small-scale beneficiation tests for them. As a result, a beneficiation process and iron ore processing production line were designed. The final beneficiation index far exceeded the previous beneficiation production line index of the two major steel companies. For this reason, both Yili Steel Plant and Hejing Steel Plant introduced several Ferui iron ore processing production lines. To replace the previous iron ore processing production line to greatly reduce the cost of iron ore processing.

Fore Machinery has designed an iron ore gravity separation production line for Xinjiang steel enterprises. The production line includes crushers, vibrating screens, jigs, dewatering screens, conveyors, feeders and other equipment. All equipment investment is only strong magnetic separation equipment And one tenth of the magnetized roasting equipment, and the beneficiation efficiency and beneficiation index are significantly higher than the strong magnetic separation and magnetized roasting, which has won unanimous recognition and praise from customers. At present, the two major steel companies purchase Ferui Machinery iron ore processing The production lines have been put into operation normally and have achieved good results, which greatly reduced the cost of iron ore processing and realized the turnaround of iron ore processing projects.

It is understood that most of the iron ore in Xinjiang belongs to hematite and specularite. The grain size of iron minerals is relatively coarse, and the specific gravity difference between iron minerals and gangue is obvious. Gravity separation is the most ideal method. As a sorting equipment, the jigging machine can greatly reduce equipment investment and production costs. Xinjiang steel companies can completely abandon the high-gradient strong magnetic separation production line and the magnetized roasting production line.

The processing of iron ore needs to design the processing flow and equipment configuration according to the nature of the ore. It is not blindly copied according to the theory. The applicability of the strong magnetic separation and magnetization roasting process is limited and the equipment investment is huge, and the production cost is high, which is completely unsuitable. In the current downturn in iron ore, if you want to reduce the cost of iron ore processing, you must have a thorough understanding of the physical and chemical properties of iron ore, and tailor-made iron ore processing production lines based on these properties can ensure energy-saving, high-efficiency, and environmental protection requirements. .
