the most important steps of mineral processing

  • Metallurgic Processes | Boundless Chemistry

    The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore; Since most minerals are not pure metals, further separation methods are required.

  • 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-resistant plate/surface.
