Also, bauxite mining severely affects the water retention capability of the soil. The Jamaican Mining Act of 1947 requires mines to remove topsoil before mining, and restore it as part of the reclamation process. However, due to the enlargement of the surface area after mining, and the extraction of much bauxite, the soil is less capable of retaining water. Where formerly annual crops were grown, now only tree crops and pasture are feasible, and water

05/02/2016 The water quality in the area was officially classified as Class Three, meaning it would require intensive treatment. “[T]he fish sold here are caught in the deep sea and not in the polluted coastal areas, yet people are afraid to buy them, fearing that they may be contaminated with the residues from bauxite mining activities,” one of them told The Malaysian Insider.

Bauxite mineral is used directly, to remove phosphates from water, in a high efficiency, highly economical system. The process of the invention involves the step of contacting the waste water stream with Bauxite for a time sufficient to lower the phosphate concentration to a predetermined lower level. The predetermined lower level is typically less than about 2 mg/l of water, and can be to a ...

17/12/2016 As a result, there have been ongoing water quality and waste management problems at many mines. There have been a number of preventable accidents including massive sediment loading into fish-bearing streams, the building of roads with acid generating waste rock, non-compliance with waste handling plans, and repeated violations of water quality standards.

The Process: Bauxite to Alumina to Aluminum. Aluminum is hidden in an ore called Bauxite. It’s a red dirt and clay mixture commonly found in Australia, Brazil, and India. If you’re looking for shining bits of silver in the ground, though, you won’t find it. Aluminum as we know it has gone through a lot to get to our supermarket shelves (among other amazing uses). Bauxite is collected ...

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 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 revegetation of ...

01/01/2019 Is bauxite residue an economic or a technological problem? Bauxite residue is strongly alkali (high pH values) because it contains high concentrations of lye (NaOH). This is why it cannot simply be discharged into the natural environment. In itself, NaOH is not so difficult to deal with and can be neutralised using substances such as hydrochloric acid (HCl) to produce clean water and table ...
