• Lead sulphite passivated galena surfaces. Sulphite ions interacted with free lead to form sulphite. Dithionite decomposition products degraded xanthate in solution. are potential determining at the mineral surface. The recovery of sulphide minerals is depressed high dithionite concentrations. Sulphoxy anions recycled flotation process waters possess reduce efficacy reagents. In this study, an...

The grinding process plays a crucial role in the floatability of mineral. present study proposes scheme to assist flotation separation galena and pyrite by optimizing choice media. effects media (cast iron balls, steel balls containing 18% chromium, 12% chromium) on pulp properties hydrophilicity were evaluated using tests, micro-flotation X-ray photoelectron spectroscopy, adsorption capacity a...

Bacterial adhesion to mineral surfaces plays an important role not only in bacterial survival in natural ecosystems, but also in mining industry applications. Selective adhesion was investigated with Thiobacillus ferrooxidans by using four minerals, pyrite, quartz, chalcopyrite, and galena. Escherichia coli was used as a control bacterium. Contact angles were used as indicators of hydrophobicit...
