Abstract:There are two identical processes of iron separation in an iron ore separation plant in Liaoning province. In this process, “twice magnetic separation +twice column washing” is used to carry out the concentration operation after twice grinding. The process uses more magnetic separation equipment, and the separation process is more complicated. With the increasingly prominent problem of “poor and fine” ore mined, the grade of iron concentrate produced by the existing process of the concentrator is reduced. In order to solve the above problems, the cleaning process was reformed, and a BKZ2000 electromagnetic washing and cleaning machine was used to replace the cleaning operation of the existing two iron sorting processes, and 66.19% concentrate grade was obtained, which was 0.85 percentages higher than before the transformation.The BKZ2000 electromagnetic washing and cleaning separator realizes the short process operation of refining in the sorting plant, and can save 1.2 million tons of water and 0.9 million kW of electricity per year, achieving better economic and environmental benefits.
