Bauxite mining and rehabilitation

Rehabilitation means that bauxite mining is a form of temporary land use [5]. On completion of the mining operations, the mined area is returned to a form suitable for further use. In the context of sus- tainable development, this conforms with the sur- rounding landscape from ecological, economic and social points of view.

Mining and Refining

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 post-mining

Bauxite mining in Australia

Australia is the world's largest bauxite producer, producing almost a third of global bauxite. [2] Bauxite is mined in Australia using open-cut mining, which suits the relatively shallow bauxite deposits located mostly in Western Australia and Queensland. [2] [4] Mined bauxite is either exported or refined domestically into alumina.

Sierraminbauxite – Unearthing Responsibly

In Sierra Leone, bauxite mining started in the sixties and presently exports are several million tons per annum. The washed bauxite is considered one of the best quality ore for low temperature alumina refineries. The Port Loko bauxite deposit may be considered an extension of the same bauxite belt which is well known in Sierra Leone.

TENORM: Bauxite and Alumina Production Wastes

26.09.2022The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
