ABSTRACT:
A process for treating thickened phosphatic clay suspensions produced in the processing of phosphate ore by water beneficiation, and which have a solids content of from about 5% to about 30%. A deflocculating agent is mixed with the suspension to cause deflocculation of the suspension to an extent sufficient to reduce the viscosity of the sludge to a value enabling the deflocculated suspension to be readily pumped from one location to another. The deflocculated suspension is subsequently mixed with an additive compound comprising an alkaline earth metal oxide or hydroxide in an amount sufficient to cause the formation of large silicate molecules with resultant gelling and setting of the sludge into an inert solid material.
