Sulfidizing Flotation Tests of Cerusite and Limonite

The influences of the dosage of Na2S, pH values,sulfidization time and the types of pH modifiers on the flotation of cerusite and limonite have been studied in this paper,and the performance of ethyl xanthate,butyl xanthate,isobutyl xanthate,amyl xanthate and isoamyl xanthate are studied in detail respectively.The results of the tests show that cerusite can be floated well in the certain condition by means of sulfidization method,and limonite is difficult to be sulfidized,which has low flotation recovery.Isobutyl xanthate is the best collector to float cerusite in the the xanthates.The contents of limonite have influence on the flotation recovery of cerusite,and the more content of limonite,the higher flotation recovery of cerusite.
