auriferous mining deposits in argentina

Auriferous Deposits Mineral Processing & Metallurgy

Gold and elements of the platinum group metals have been found in several types of deposits around the world. Sometimes, deposits have been worked for their cobble and gravel components and these places have been set up to recover heavy minerals (mainly as black sands) from their host rock. These minerals carry precious metals and they can be recovered by gravimetric devices such as shakingget price

Hydrothermal mineral deposit Wikipedia

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.In some occurrences, minerals can be extracted at a profit by mining.get price
