Mineral extraction The removal of solid mineral resources from the earth. These resources include ores, which contain commercially valuable amounts of metals, such as iron and aluminium; precious stones, such as diamonds; building stones, such as granite; and solid fuels, such as coal and oil shale. Overcultivation
Get Price· The MIT researchers found a promising method of forming liquid copper metal and sulfur gas in their cell from an electrolyte composed of barium sulfide, lanthanum sulfide, and copper sulfide, which yields greater than percent pure copper. This purity is equivalent to the best current copper production methods.

Get Price· A landlocked lake in China called Lake Zabuye provides a salt water brine which contains lithium carbonate. The lake is supplied with a combination of rain water, melting ice, and underground water sources. Lithium is extracted from the salt water brine and was China's primary source of lithium in 2008. As the demand for lithium has risen in ...
Get PriceThe production of ore for metal manufacture, mineral products for industrial processes and rock and stone material for building purposes all presuppose the extraction of valuable material from the bedrock. The conditions for ore, industrial mineral and aggregate production are quite similar and they all face very much the same challenges.
