bauxite ore mining extraction process

Other sources of vanadium include ash from the combustion of fossil fuel, slag from phosphate ore, the aluminum ore bauxite, and spent catalysts. Mining. Because vanadium is essentially the by-product of ores that are mined for other minerals, they are mined by methods peculiar to those ores. Extraction and refining Vanadium pentoxide

Bauxite Ore Extraction Process. Unlike other base metal ores, bauxite ore does not require complex extraction processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay. In many cases, bauxite ore extraction process can be accomplished by some combination of washing, wet screening, …
