Alizarin Red S as a Flotation Modifying Agent in Calcite Apatite .

In this paper, results obtained for oleate flotation of apatite and calcite using a dye, alizarin red S, as a modifying agent are pre sented. Alizarin red S was selected for this study because of its use as a selective staining agent for calcite (Friedman, 1959). The mechanism involves the reac tion of Ca2 + ions with the reagent.

Since Silica is not high, cleaning phosphate ores in alkaline pH two times is sufficient, using sodium oleate as collector, before separating apatite from calcite. Calcite is very difficult to separate from phosphatic ores. Even though you achieve +28% P2O5 which is acceptable in fertilizer industries, still you will be losing.
