analysis of phosphate deposit disturbances using the phosphate rock

Fractal Assessment of the Disturbances of Phosphate Series

Abstract. In Sidi Chennane phosphate deposit, the disturbances cause serious challenges for the OCP mining engineers during both exploration and the exploitation stages. They are qualified as worst rocky hard to be quantified since they interfere with phosphates series.

World Reserves of Phosphate Rock - Dynamic, Unfolding Story

Phosphate rock occurs in both sedimentary and igneous deposits across the world (Figure 1). Most (80 to 90 per cent) of PR used to produce fertilizer is sedimentary in origin, and was deposited in ancient marine continental shelf environments. Sedimentary deposits, sometimes called phosphorites, occur throughout geologic time.
