US4083929A Beneficiation of phosphate rock Google

Beneficiation of phosphate rock containing limestone is accomplished by calcining, cooling, slaking and separation of the slaked lime from the phosphate rock product. The cooling, slaking and separation operations are conducted in a fluid bed reactor.
