Crushing in Mineral Processing
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 …

Silicon carbide manufacturing process
The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating it with graphite at 1500°C (2730°F). The material formed in the Acheson furnace varies in purity. The silicon carbide "stones" and grains are turned into a fine powder by crushing, and then purified with halogens.
