copper sulphide ore reagents for copper flotation

Flotation of Copper Ores When the ore is free from pyrite the function of the lime whatever the reagent mixture is to precipitate dissolved salts and to maintain the alkalinity of the pulp at the value which has been found to give the best results soda ash is seldom employed for this purpose
