Abstract:
This paper describes the characteristics of copper smelter slag, which are very influential in the process of flotation. Special attention was paid to the stability of the suspension in the flotation conditions. Zeta potential and sedimentation tests were conducted under different values of pH, concentration of solid and concentration of flotation reagents.In addition to these some mineralogical investigations were carried out on samples of slag in the piece as well as in briquette of milled samples by ore microscopy. Appearance of solid copper bearing phase and their size and shape were given in the paper. On briquettes of granulated slag sample the liberation results of the copper bearing phase under different conditions of grinding and flotation were shown and discussed in the paper.And finally some recommendations for the reprocessing of copper smelter slag in order to obtain copper by flotation were given. All test were conducted on samples of smelter slag from Mining and Smelting Bor, Serbia.
