How Is Tungsten Mined?

Tungsten is primarily sourced from scheelite and wolframite deposits found globally, with significant production in China, Russia, Canada, and Bolivia. Scheelite (CaWO4) appears in various colors and forms in hydrothermal veins and greisen deposits, while wolframite ((Fe,Mn)WO4) is typically black or brown, found in quartz veins and pegmatites. Both minerals are crucial sources of tungsten, vital for industrial applications due to their high tungsten content.

The tungsten mining process includes prospecting, extraction, crushing, beneficiation, and refining. Extraction often involves open-pit mining with heavy machinery or underground mining for deeper deposits. Once extracted, the ore is crushed and undergoes beneficiation to separate tungsten from waste, using methods like gravity separation and flotation. The concentrate is then roasted to remove impurities and convert tungsten minerals into tungsten oxide (WO3), which is reduced to produce pure tungsten metal for various uses.

Common Tungsten Forms

Tungsten is available in various forms, tailored to specific uses and processes. Tungsten oxide (WO3), generated during the refinement of tungsten ore, is a yellowish or bluish powder utilized as a precursor for tungsten metal, in the creation of tungsten alloys, and as a catalyst in certain chemical reactions. Tungsten carbide (WC), a blend of tungsten and carbon, is exceptionally hard and frequently employed in the production of cutting tools, drill bits, and abrasives due to its remarkable wear resistance. Tungsten alloys, often combined with nickel, copper, iron, or cobalt, are prized for their high density, strength, and superior thermal and electrical conductivity, making them suitable for applications in aerospace, defense, electrical contacts, and radiation shielding.
