With collector dosage increasing, the recovery rate of calcium minerals increases to 90%, and the recovery rates of calcite and fluorite are higher than that of scheelite.Metals recovery by flotation American, Cyanamid,The success of a flotation process depends to a great degree on the reagent(s) called collector(s) that impart(s) selective hydrophobicity to the valuable mineral that has to be separated from other minerals. Thus, the flotation separation of one mineral species from another depends upon the relative wettability of mineral surfaces by water.
