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.
