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.

Dec 31, 2016· Australia produced 82 Mt of bauxite in 2016, slightly up from 2015 levels (81 Mt; Table 1). In contrast, the USGS estimates that during 2016, global bauxite production decreased 11% owing to the Malaysian ban on bauxite mining in response to environmental concerns. Table 1.

Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world''s production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

The first step in producing aluminium is mining its ore – occurs mainly in tropical and subtropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe. Australia is the largest producer of bauxite, with five mines supplying around 23 per cent of global production.

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.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
