Study of Flotation Parameters for Copper Recovery from ...

2020-4-1  In common practice the regulating reagents are using to control the adsorption of collectors in flotation operation. In order to depress zinc and iron sulfides from copper-pyrite ores, flotation process is conducted in an alkaline medium, which is created by pH modifiers. Discovery of optimum type and dosage of a modifier is one of effective way to enhance the flotation performance. The change in pH level influences on mineral surface, behavior of a collector and soluble salts in the pulp. There is the competition between soluble ions in pulp and a collector to adsorb on the mineral surface. It has been established that each pH reflects on different concentration of collector ions leading to maximum recovery of copper.
