The crushing and scrubbing plant can successfully handle the beneficiation of friable phosphate ore. In the crushing and scrubbing plant, the phosphate ore is initially screened on 60 mm screen and the oversize is crushed by a jaw crusher to -10 mm. To control the degree of -0.5 mm fines to about 15% weight in the run of mine (ROM), the …

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.
