How Is Tungsten Mined?

Tungsten, also known as wolfram, is primarily sourced from scheelite and wolframite mineral deposits found worldwide, with leading tungsten production concentrated in countries such as China, Russia, Canada, and Bolivia. These tungsten-bearing minerals serve as the backbone of the global tungsten supply chain, fueling applications in high-performance manufacturing, electronics, defense, and energy sectors. Scheelite (CaWO4) is often found in various colors and crystal forms within hydrothermal veins and greisen-type ore bodies, while wolframite ((Fe,Mn)WO4) typically appears as black or brown tabular crystals in quartz veins and granitic pegmatites. Both are essential for industrial use because of their high tungsten content and favorable mining characteristics.

The tungsten mining process is a multi-stage operation that involves several critical steps to ensure efficient and responsible extraction. The initial step is prospecting, where geologists conduct surveys and exploratory drilling to locate and map economically viable tungsten ore bodies. Once identified, extraction follows, utilizing either open-pit mining for shallow deposits or underground mining techniques for deeper, less accessible ore. Open-pit mining uses heavy earth-moving machinery such as excavators, loaders, and haul trucks, while underground mining involves complex tunneling and drilling operations.

After extraction, the raw tungsten ore undergoes crushing and grinding to liberate the tungsten minerals from surrounding rock. The next phase, beneficiation, separates tungsten from waste material (gangue) using advanced concentration methods such as gravity separation, froth flotation, and magnetic separation—the choice of method depends on the mineralogy and particle size. The resulting tungsten concentrate is then roasted at high temperatures, a process which removes residual impurities and converts the mineral to tungsten oxide (WO3). The final refining step reduces tungsten oxide to pure tungsten powder or ingots through high-temperature hydrogen reduction or other metallurgical processes, readying it for downstream industrial applications.
