Mineral processing - Wikipedia
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the Comminution may be carried out on either dry materials or slurries. Crushing is a dry process whereas grinding is generally performed wet and hence is of methods like flotation, classifiion, magnetic separation and leaching.
