Tungsten Mining & Beneficiation International Tungsten

On the other hand, ore concentrates traded internationally require 65-75% WO 3. Therefore, a very high amount of gangue material must be separated. This is why ore dressing plants are always located in close proximity to the mine to save transportation costs. The ore is first crushed and milled to liberate the tungsten mineral crystals.

Ore washing plant for sale, high efficiency ore washer LZZG

The most common application for washing is as a preparation before the sorting. In the treatment of iron ore, the coarse-grained ore-free waste rock is separated by the washing method, and the obtained fine-grained portion is further selected by deliming to reduce the amount of treated ore. resulting in poor ore dressing results. Therefore
