· Present work focuses on the differences in the performances obtained in the froth flotation of copper smelter slag with multiple collector viz. sodium iso-propyl xanthate (SIPX), sodium di-ethyl dithiophosphate (DTP) and alkyl hydroxamate at various dosages. Flotation tests were carried out using single collectors as well as various mixtures of ...
· The specific procedures are as follows: 1) A flotation process was adopted to enrich copper, and when the copper grade in the flotation concentrate was 21.50%, the copper recovery rate was 77.78%.
· The optimal closed-circuit flotation test flowsheet was designed based on the results of single-factor condition experiments.It is particularly pointed out that adding sodium carbonate (Na 2 CO 3) before ball milling is to increase the possibility of copper-bearing mineral liberation from gangue minerals .The balance results after five cycles of testing are shown in Table 1.
· Considering the fact that copper ions inevitably exist in the pulp of the Cu-Zn sulfide flotation system, the sphalerite treated with Cu 2+ (5 × 10 −6 mol/L) was used for zeta-potential measurement, and the concentration of the other reagents was kept the same with the optimal dose of flotation reagents used in Fig. 4(a).

· In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective ...
flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity …
