Environmental impact. overall, the entire process of transforming raw bauxite into aluminum is incredibly energy intensive, requiring copious amounts of electricity, water and resources to produce that is the main reason why power plants are built solely to support the aluminum industry.
Handarm vibration syndrome seems to be rare in bauxite mining and alumina refining. vibrating hand tools are not an important part of the process at bauxite mines, but are common at alumina refineries. nevertheless, most bauxite mines and alumina refineries are located in tropical climates, so coldprovoked vasospasm is less likely.

Ing was the main bauxite mining technique in use. since then, however, the process has shifted to the more economical, safe and environmentally friendly surface mining, and today wirtgen surface miners extract 100 of the ore. since 2001, the wirtgen technology has proven its additional benefit to the growing bauxite mining industry in.
Later, the bauxite industry was further consolidated, with the opening of the alumina plant in 1961, where alumina was produced using the bauxite tailings or waste. at the plant some of the bauxite was transformed into alumina, before its export to world markets, for further processing into aluminum.
Life cycle assessments of the mining and mineral processing of iron ore, bauxite and copper concentrate were carried out, focussing on embodied energy and greenhouse gas emissions. the results showed that loading and hauling make the largest contributions to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.
