Comminution in mining -

Comminution is the most energy intensive process stage in the mining industry. It accounts for up to 40 percent of the total energy used in mineral processing operations. While the head grades are constantly declining, more sustainable technologies and solutions are required to process hard, variable and low-grade ore bodies.

Materials processing

Forming and shaping processes may be classified into two broad types—those performed on the material in a liquid state and those performed on the material in a solid or plastic condition. The processing of materials in liquid form is commonly known as casting when it involves metals, glass, and ceramics; it is called molding when applied to plastics and some other nonmetallic materials.

Metallurgy - Wikipedia

The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense in the 1797 Encyclopædia Britannica. In the late 19th century it was extended to the more general scientific study of metals, alloys, and related processes.

Extractive Metallurgy | Introduction to Chemistry

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores (leaching).

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.
