the mining process of tungsten in Armenia

Tungsten: extraction and processing-Metalpedia

The common tungsten extraction methods are surface (or open pit) mining and sub-surface (or underground) mining, or a combination of both. Modern tungsten processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, and tungsten can also be recycled from Scrap.

Crushing in Mineral Processing

2015-12-26  In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
