An investigation was tmdertaken to determine the effect of grinding on the acidulation of phosphate rock. Bench-scale work was carried out in a one quart, laboratory ball mill made of stainless steel* The mill was equipped with a heating chamber so that the material could also be dried in the mill. The results flxam this »joik.
Phosphate rock (PR) is an abundant ore and represents the basic raw material for the phosphatic fertilizer industry. Prior to industrial processing, PR is concentrated by grinding-and-screening to separate a fine fraction that is very poor in P(2)O(5). This fine fraction is a solid waste and represents a disposal problem.
