To process the bauxite, the bauxite must be mined, crushed, and delivered to the refinery. The first step to reaching the refinery after mining the bauxite is crushing. The crushing circuit is defined by a series of variables and how those variables come together to affect each other. Those variables include the following:
Enhance base metal mining efficiency with analytical solutions to reduce wasted spend, improve base metal grading, separation and refining.
In general, the crushing circuit equipment selection for a bauxite mine is based on the site-specific variables related to the application, and not based solely on the fact that this is a bauxite mine versus a mine for some other type of ore. A crusher does not know what type of material is passing through it.

Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers. The topsoil is then stored and later used for revegetating and restoring the area after mining is completed. The underlying bauxite is mined by front-end loaders, power shovels or hydraulic excavators.
