Experimental Study on Mineral Separation of a Copper-Tungsten Ore

This article introduces the experimental study on mineral separation of a copper-tungsten ore.

Through the study of process mineralogy,ore chemical composition,mineral composition,pore-imbedding stains relationship,particle size distribution characteristics are identified.The process of preferential flotation of copper-heating cleaning of scheelite-gravity separation of wolframite with shaking table is adopted.As a result,better experimental indexes are achieved with copper recovery as 94.64 %,copper concentrate grade as 23.04 %,scheelite concentrate grade as 60.35 % and the total recovery of tungsten as 76.41 %.
