Reducing the production cost of concentrates can currently be achieved by mining high grade raw ores or improving the beneficiation process. Because domestic mines are generally poor ores and few rich ores, the approach of mining high-grade raw ores is almost impossible for most domestic separation plants, and the production cost of concentrate can be reduced only by improving the separation process. In the long development process, the mineral separation process is only limited to be improved by means of ways such as 'more crushing and less grinding', 'less grinding and more selection', and continuous development of novel flotation reagents or flotation equipment.
In the existing magnetic separation equipment, the existing magnetic separation equipment mostly separates magnetic ores or weakly magnetic ores, such as wet-type cylindrical magnetic separators, high-gradient strong magnetic vertical rings and other products, and the like are fully used from dry type to wet type and from permanent magnet to electromagnetism; but because most of the colored ores are extremely weak in magnetism, the specific magnetization coefficient is only 10X10 in order of magnitude-9m3Perkg, weakly magnetic ore (100X 10)- 9m3/kg) is lower by one order of magnitude, and the existing magnetic separation equipment cannot be used for the ultra-weak magnetic ore. Therefore, a large-scale separation device which can separate the ultra-weak magnetic colored ores, has the advantages of high recovery rate, low water consumption and high automation degree and can achieve the ideal separation target is urgently needed.
