platinum mining, mining of platinum, platinum, platinum ...In South Africa's Bushveld complex and a limited number of other ore bodies, platinum group metals occur in sufficient quantities so as to make it cost efficient to extract these metals. At Russia's Norilsk and Canada's Sudbury deposits, the metal and other PGMs are extracted as by-products of nickel and copper. Extracting platinum from its ore is both capital and labor intensive. It can take ...Glossary of Mining Terms - SECBessemer- An iron ore with a very low phosphorus content. Bio-leaching- A process for recovering metals from low-grade ores by dissolving them in solution, the dissolution being aided by bacterial action. Biotite- A platy magnesium-iron mica, common in igneous rocks.

    Bioleaching is the extraction of metals from their ores through the use of living microorganisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt. The other alternative extractions ...Extracting Metals from E-Waste Costs 13 Times Less Than ...· "The researchers conclude that with these offsets, it costs 13 times more to obtain these metals from ore than from urban mining," the ACS says. Although the study was limited to copper and gold extracted and processed from e-waste streams made up of recycled TV sets, the researchers say their results indicate a trend and potential to be applied across a broader range of e-waste sources ...Metal Extraction - an overview | ScienceDirect TopicsBiocoke is an important reducing agent, and is produced specifically for metal extraction to substitute for conventional coke that is produced from coal.
