Experimental Study on Carbon Low Phosphorus Medium Magnesium High Silicon Phosphate Ore in Yunnan Province
A phosphate rock in yunnan province is dark gray in color and contains inorganic carbon source(graphite).The content of P2O5 is 19.50％,the content of MgO is 3.48％,the content of SiO2 is 30.41％.The concentrate P2O5 28.81％can be obtained by the closed-circuit process of one-stage decarbonization flotation,one-stage desilication roughing,one-stage desilication sweetening,one-stage demagnesium flotation and one-stage desilication sweetening,P2O5 recovery rate of 57.75％of the separation index,to achieve the effective recovery of this kind of phosphate rock resources.
