The Measures of Upgrade the Concentrate of Dexing Copper Mine

Guofan Zhang

Abstract

According to the result of Dexing Copper mine flowsheets examination, it was ascertained that what has mainly influence on the grade of chalcopyrite concentrate was pyrite, and then gangue. Based on the development in mineral separation of world porphry copper mega-deposit, the possibility of using fractional flowsheet, reagent, flotation column to upgrade the concentrate of Dexing Copper mine is primarily discussed in this paper.
