Tantalum Mining Process. The tantalum concentrate is transported to the processor for chemical processing. The concentrate is then treated with a mixture of hydrofluoric and sulphuric acids at high temperatures. This causes the tantalum and niobium to dissolve as fluorides. Numerous impurities are also dissolved.

Reforming. The process of reforming was developed to raise both the quality and volume of gasoline produced by refiners. Using a catalyst again, after a series of reforming processes, substances are converted into aromatics and isomers, which have much higher octane numbers than the paraffins and napthenes produced by other refinery processes.

Tired of seeing coltan from its Kivu and Tanganyika mines processed and re-exported by its neighbours, Kinshasa plans to create facilities and smelters to process the ore on site. The initiative comes amid a warming of relations between the DRC and Rwanda, the country through which most of its coltan passes.

Coltan. Coltan is short for columbite-tantalite, a dull metallic ore. When refined, coltan becomes a heat resistant powder, metallic tantalum, which has unique properties for storing electrical charge. Coltan occurs in granitic pegmatites, pockets where the deep seated molten rock crystallized last. Pegmatites contain many rare metals, as well ...

Salt/Halite Mining Process. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.
