Tungsten Ore Production

The main component of tungsten ore is tungsten.Tungsten is a dull silver-colored metal with the highest melting point of any pure metal.Also known as wolfram, from which the element takes its symbol, W, tungsten is more resistant to fracturing than diamond and is much harder than steel. It is the refractory metal's unique properties - its strength and ability to withstand high temperatures - that make it ideal for many commercial and industrial applications.

Production:

Tungsten is primarily extracted from two types of minerals, wolframite and scheelite. However, tungsten recycling also accounts for about 30% of the global supply. China is the world's largest producer of the metal, providing over 80% of the world supply.

Once tungsten ore has been processed and separated, the chemical form, ammonium paratungstate (APT), is produced. APT can be heated with hydrogen to form tungsten oxide or will react with carbon at temperatures above 1925°F (1050°C) to produce tungsten metal.
