Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of bauxite ores through selective grinding by exploiting the di erent grindability between the minerals of interest, e.g., diaspore (6.5–7 Mohs hardness) and Options of Bauxite Ores MDPI

How will the bauxite crusher work? LinkedIn
To begin the crushing process, the bauxite is fed into the crusher. The crusher breaks the rock into smaller pieces, and then the material is conveyed to a screening plant, where it is sized andIn the case of copper ore, it is the crushing and grinding (particularly the latter) steps that make the largest contribution (approximately 46%) to the total greenhouse gas emissions for the mining and processing of copper ore (628 kg CO 2 e/t concentrate). These results indicate that efforts to reduce the increased greenhouse gas emissionsEnergy and greenhouse gas impacts of mining and mineral processing

What is bauxite used to make? and how to extraction process
The preparation of bauxite typically involves mining, crushing, grinding, and leaching processes. The specific steps may vary depending on the quality of the ore and the extraction process, butBauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier.
