Cobaltite (CoAsS) is a strategically important mineral. This work investigated the bioleaching of cobaltite-bearing magnetite-rich ore. The bioleaching of cobaltite was carried out with mixed mesophilic and moderately thermophilic cultures at 4, 8, and 12% pulp densities in shake flasks.The concentrations of bournonite, tennantite, cobaltite, and clausthalite can be assumed to be zero, such that all Sb is hosted by tetrahedrite, all As by arsenopyrite, and all Pb by galena.

Gold and silver contents in Noril’sk ore are controlled by the amount of sulphides and bulk Cu grade. Relative concentrations, re-calculated to 100 % sulphide, depend on type of ore: they are higher for disseminated ore than for massive ore and are the highest for low-sulphide platinum ore. Gold occurs mainly as high-fineness Au–Ag alloy This paper addresses the need for investments in ore beneficiation and scrap upgrading in the decades to come in order to meet demands on mitigating emissions of greenhouse gases as discussed at the AIST Scrap Supplements and Alternative Ironmaking 8, Orlando 2020 (Gyllenram et al. 2020).The theme of the conference was Driving investments in ore beneficiation and scrap upgrading

Agitation leaching is a promising technology in hydrometallurgy for treating copper–cobalt oxide ores. In this work, the behavior of oxide ores containing around 2.3% Cu and 0.3% Co received from Congo was investigated for varying particle size, acidity, pulp density, temperature, leaching time, and reduction potential. XRD, optical microscopy Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include.Ore Beneficiation an overview ScienceDirect Topics
