Bauxite Mining Encyclopedia of Arkansas

Many of the early-mined Arkansas bauxite deposits were exposed on the surface as outcrops or were beneath only a thin layer of sedimentary cover. Consequently, surface-mining methods were initially the most practical and economical. Before and during World War II, significant tonnages were mined underground. Some years after the war, surface

Sustainable Bauxite Mining Guidelines

2018-5-30  Sustainable Bauxite Mining Guidelines ii Executive summary . Bauxite, the primary ore used to make aluminium, is refined into alumina, which is then smelted into aluminium. Other uses of alumina include chemical grade applications. Bauxite demand has historically been met by a few large players in the market, which have operated large scale mines.

This has caused mining costs to become a more important factor than location near a smelter. Environmental Issues caused by bauxite mining. Due to the methods of mining (open cast), the end result of mining on the landscape is very unsightly. Jamaican regulations ensure that the land is reclaimed when mining in an area is complete.

Post-mining deterioration of bauxite overburdens in

degradation of disturbed soil from a karst bauxite mine in Jamaica was recorded. Substantial macronutrient losses were incurred during a short (1 month) or a long (12 months) storage of the replaced topsoils during frequent wet/dry changes. The results suggested very high rates (>70% in the first year) of soil degradation from storage, alongside moderate rates (30%) within the same

Restoration of Forested Lands under Bauxite Mining

Mining poses a major environmental threat to tropical forest ecosystems, given its role in long-term forest degradation. Like Suriname, Guyana presents one of the less disturbed forested lands in South America. The local economy is improving, thanks to the development of mining which is primarily focused on gold, diamond, and bauxite. This, however, has resulted in long-term degradation of
