Phosphate Beneficiation

Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or "matrix" as it is called locally, contains three different mineral groups which have to be separated from each other.

Mechanism of calcium lignosulfonate in apatite and dolomite …

Since the physical and chemical properties of apatite and dolomite can be similar, the separation of these two minerals is difficult. Therefore, when performing this separation using the flotation method, it is necessary to search for selective depressants. An experimental research was performed on the separation behavior of apatite and …
