Kinetics And Recovery Of Xanthatecopper

The recovery of copper in aqueous media by ion flotation in a laboratory flotation cell was carried out. Hydrodynamics and gas dispersion parameters were obtained. The results show that the increase of potassium amyl xanthate concentration above the stoi-chiometric amount considerably affects the efficiency of the separa-tion of copper.

Multidimensional Optimization Of The Copper Flotation In A

Three factors were measured in the flotation process of copper ore the copper grade in a concentrate , the copper grade in tailings , and the recovery of copper in a concentrate . The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size d, the flotation time t, the type of collector k, and the dosage ...
