An Overview Of Technologies And Selective Depressing

In the flotation process the depressor adsorbs on the mineral surface to form a hydrophilic film to prevent the collector from interacting with non-target minerals. According to previous studies the main depressors for talc can be classified into several categories Table 1. Table 1 Depressors for talc.
