Experimental Study on Process Mineralogy and Magnetic Separation Recovery of an Iron-Based Alloy Waste
In order to realize the resource utilization of metal iron and iron oxides in an alloy scrap,the process mineralo-gy was studied by means of chemical multielement,iron phase,MLA and SEM-EDS.The results showed that the main material composition of the raw material is metal iron and the content is 77.52％;The contents of iron oxide and aluminum oxide were 11.13％and 8.97％,respectively.The particle size of the main substances in the raw material is fine,and the yield of iron ox-ide and metal iron below 38 μm is 72.53％and 63.66％,respectively.The monomer dissociation degree of metal iron and alu-minum oxide in raw materials is high,and the monomer dissociation between metal iron,iron oxide and aluminum oxide can be realized by grinding.The concentrate with iron grade of 84.92％and iron recovery rate of 92.37％was obtained by magnetic separation of raw materials.The dealuminization effect was good,but the effective removal of silicon could not be realized.
