Jul 01, 2020 Copper and sulfur in copper ore have strong collection properties, which is also conducive to improving the recovery of associated gold in copper sulphide ores. The flotation effect of refractory copper-sulfur ore containing secondary copper minerals is better than that with butyl xanthate, but its selectivity is worse.
Following flotation, it was seen that copper, cobalt and sulfur present in the medium were concentrated. In this solution, concentration of copper and cobalt were found five times higher than normal level. Key Words Oxidized copper ore, sulfurization, flotation, copper, cobalt, sulfur INTRODUCTION
Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5, chalcopyrite 4-5 and pyrrhotite 30-35. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.
the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals ...
Copper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead ...
