Drakelands Mine - Wikipedia

The Drakelands processing plant relies on a number of different processes to recover tin and tungsten and discard gangue minerals such as arsenopyrite and haematite. Broadly speaking, the process involves crushing and sizing, followed by gravity separation on fine material and dense media separation (DMS) on coarse material. The concentrates from these processes are then milled, followed by flotation and roasting, finishing with magnetic separation and further gravity separation to produce the final tung…

Tungsten Mining & Beneficiation | International Tungsten ...

Tungsten mines are relatively small and rarely produce more than 2000t of ore per day. Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than 1.5% WO 3 and frequently only a few tenths of a percent. On the other hand, ore concentrates traded internationally require 65-75% WO 3. Therefore, a very ...
