These processes include extracting hi purity nickel from laterite ores zero-cyanide gold and silver processes economically viable treatment of refractory and arsenic-containing ores titanium and vanadium extraction processing PGM from massive sulphide-based ores and rare metals recovery Our Patents are ready We bring into the 21st Century a suite of novel progressive mining
Metal ores are formed in the process of ore genesis and they are extracted through mining Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form Hydrometallurgy uses aqueous solutions to extract metals from ores (leaching)
Mineral processing can involve four general types of unit This process is only viable for coarse ores that have a close size distribution as the apertures can allow small particles to pass through Sedimentation operates by passing water into a large thickener or clarifier In these devices the particles settle out of the slurry under the effects of gravity or centripetal forces These
