Yuanjiacun iron ore dressing equipment manufacturer in Taizhaoyu Mining Area, Shanxi Province. By the end of 1990, the accumulated proven reserves and reserves of the whole district were 89.45 million tons. The ore types were quartz and amphibole, with oxidized ore and primary ore. The size of the ore inlay is fine, and the particle size of the magnet and hematite is 75%~80% less than 0.043mm, of which the quartz type iron ore is 20%~0.010mm, and the amphibole type iron ore is 40%~-0.010mm. The ore grade iron is lower, which is a complex and difficult to choose iron ore. Kunshan Iron and Steel Dahongshan Iron Ore Dressing Equipment Factory is a magnetite-hematite mixed ore with a reserve of about 460 million tons, including nearly 200 million tons of hematite. Due to the fine grain size of ore, the composition of gangue minerals More complex, low ore dressing index, is also a complex and difficult to choose iron ore. Xuanlong-style and Ningxiang-type iron ore dressing equipment manufacturers account for about 12% of China's total iron ore reserves, accounting for 30% of China's red iron ore reserves. Due to the fine grain size of ore, the ore structure is braided and contains harmful impurities. High in phosphorus , it has not yet been developed and utilized. Iron header Baiyunebo large complex multi-metal symbiotic iron, iron in addition, there are rare, niobium and other metals, elements 71 have been found, more than 170 kinds of minerals, ores many types, wherein the rare earth reserves in the world first place. Since the ore dressing research of this ore began in the 1960s, a number of research institutes at home and abroad cooperated with Baotou Steel to carry out a large number of experimental research work. Up to now, the process of recovering iron and rare earth by weak magnetic-strong magnetic-flotation The process, this process embodies the guiding ideology of “iron-based, comprehensive recovery of rare earth mineralsâ€, which has made a major breakthrough in the beneficiation technology of Baiyun Obo Iron Mine of Baotou Steel. Sanxiong mineral processing equipment manufacturers believe that the technology is constantly improving. At present, from the technical point of view, the iron concentrate obtained by this process has a low grade, mainly because the iron concentrate contains silicate minerals, especially potassium and sodium. High, seriously affecting the smelting effect of the blast furnace. The recovery rate of rare earth minerals is low, the total recovery rate is less than 20%, and other valuable elements are not recovered.

Currently the utilization of siderite ore and limonite iron ore resources in China is very low, most do not recycle or no exploitation. The ore of the largest number of people in China is Anshan-type sedimentary metamorphic iron ore, but some of the ore are not yet effectively exploited due to the fine grain size and complex mineral composition, such as the Jiajiabaozi iron ore of Benxi Steel, which is a poor magnetite ore. The reserves are about 150 million tons. Due to the fine grain size and complex structure of the ore, it has not yet been developed and utilized.
