Bauxite grinding and handling aids Solvay

CYQUEST® BGA positively impacts the rheological property of bauxite slurry by reducing the viscosity and stickiness during the grinding process. As a result, less energy is required and the specific energy consumption per ton of bauxite ground is reduced. This less viscous slurry is also easier to pump and again requires less energy. The overall reduction in energy consumption ultimately results in reduced

Bauxite Mining's Negative Effects on Human and

23/07/2020  Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical reagents and produces no odors. Therefore, the main impact on air quality is generally ...

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. Bauxite appears dull in luster and is reddish-brown, white, or tan in color. In 1821 the French geologist Pierre Berthier discovered bauxite

Bauxite The Aluminum Association

Mining bauxite. Bauxite is usually found near the surface of terrain and can be strip-mined economically. The industry has taken a leadership role in environmental conservation efforts. When the land is cleared prior to mining, the topsoil is stored so it can be replaced during rehabilitation. During the strip-mining process, bauxite is broken up and taken out of the mine to an alumina refinery. Once mining
