  • how can i depress carbonates in flotation

    Determination of the appropriate depressing reagents for sinking valuable minerals in the presence of collectors for carbonates is a cardinal stage in obtaining an efficient separation in the direct flotation of Mg carbonate. One of the essential challenges during flotation in the presence of Mg carbonate is the occurrence of slimes.
