Most run-of-mine (ROM) tungsten ores contain less than 1.5% WO3 and frequently only a few tenths of a percent. Ore concentrates traded internationally require 65-75%, therefore a very high amount of gangue material must be separated. Beneficiation plants are always located in close proximity to tungsten mines to save.

TOXICOLOGICAL PROFILE FOR TUNGSTEN

Mining of tungsten is almost exclusively by underground methods. Since the tungsten content of typical deposits is only 0.3–1.5% WO3, all mines have beneficiation facilities that produce a concentrate containing 60–75% WO3. During the beneficiation process, the ores are crushed and ground in stages with the fine.
