Mineral processing | metallurgy | Britannica
In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution. As a rule, comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral.

Mineral processing sometimes called ore dressing mineral dressing or milling follows mining and prepares the ore for extraction of the valuable metal in the case of metallic ores and produces a commercial end product of products such as iron ore and coal ...
Mineral processing - Wikipedia
Crushing, a form of comminution, one of the unit operations of mineral processing In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores.

The ore needs to be crushed, as a choc chip biscuit, to get the minerals out. Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock.
How to choose a method for the separation of …
With using traditional methods of the mineral separation, typically ore rises to the surface for further processing. In this case, can use any method of separation, or a combination thereof to produce the expected results at any stage of the project readiness. There is the possibility of changes in processing technology and equipment. When using the underground leaching method, you can make ...
Mineral dressing (= Orebeneficiation)
Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals.

1 Heavy medium separation put crushed ore material into the heavy medium fluid (density greater than water’s), separate the two different materials under the flotation and sedimentation process of …
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. Less abrasive and softer rocks or stones ...
Gold extraction - Wikipedia
03.04.2005 · By suspending the crushed ore in a cyanide solution, a separation of up to 96 percent pure gold was achieved. The process was first used on a large scale at the Witwatersrand in 1890, leading to a boom of investment as larger gold mines were opened up.
