Experimental Study on a Weathered Phosphate Rock in Yunnan
In view of the development and utilization of a weathered ore in Yunnan Province,a set of combined scrubbing-flotation process for weathered ore has been developed through systematic technological research,the weathered ore is raised from P2 O523.52%,MgO 1.0%,SiO226.0%to concentrate P2 O528.07%,MgO 0.85%,SiO219.89%,which meets the production requirements of downstream chemical enterprises and provides a technical basis for its development and utilization.
