Mining and Refining – Process
The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2.

Physical Bauxite Processing: Crushing and Grinding of Bauxite
The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. At the refinery further crushing and/or washing may take place before the crushed bauxite is subjected to a grinding operation for final sizing before digestion.

Bauxite Crushing Plant
Bauxite Crushing Plant. Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.

Energy and greenhouse gas impacts of mining and mineral processing
The embodied energy values were 153 MJ/t ore, 55 MJ/t ore and 8329 MJ/t concentrate for iron ore, bauxite and copper concentrate respectively. These results show that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.

Effect of bauxite aggregate in cement composites on mechanical
Note that the aggregate crushing value of the bauxite aggregate (8.0%) is much smaller than that of the granite aggregate (32.7%), which is consistent with that reported in Ref. [1]. For coarse aggregate, a higher aggregate crushing value generally corresponds to a lower compressive strength (Fig. 1). It is thus reasonable to assume …
