Five stages of gypsum production process | Stone Crusher ...
Gypsum production process. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary ...

The 5 Main Steps in Processing Diamond Ore | Multotec Canada
1- Crushing. The first step in kimberlite ore processing is crushing. This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps. Crushing is done in stages to "gently" free the diamonds from the kimberlite rock and produce a ...

Mining and Refining – Process
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
