Research on the Application of High Intensity Magnetic Separation Desliming Reverse Flotation Technology for Iron Ore
In the production process of iron ore,the overflow particle size of mixed magnetic concentrate is extremely fine and the sediment content is high.According to the current method of direct reverse flotation after concentration,the cost of reagents is high,the flotation energy consumption is high,and the quality of the concentrate is dificult to ensure.In order to solve these problems,a new technology of re grinding overflow strong magnetic separation desliming reverse flotation has been proposed.This scheme can produce tailings with a production rate of 25.84%and a TFe grade of 13.67%through a three disc strong magnetic separator,thereby reducing the amount of floating ore.Application practice has shown that after technological optimization,the grade of TFe can be increased to 64.6%,and the recovery rate can be increased to 88.14%.
