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.

The first rule deals with the conservation of mass. The total flow of the material into the process plant equals the total flow out. The second rule relates to the quality or grade of the concentrate product. In practice, it is impossible to produce a concentrate consisting of only one mineral. The third rule is a corollary of the second.
