MINING AND ORE BENEFICIATION - 1. Mining

Tungsten mines are relatively small and rarely produce more than 2000 t of ore per day. Mining is mainly limited by the size of the ore bodies, which are not very large. Open pit-mining is the exception. These mines are short-lived and soon convert to underground operations.
Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit.
