Techniques In Mining The Ore Bauxite

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.Exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who

Bauxite is the most common aluminium ore. Bauxite occurs as a weathered cover or blanket, known as laterite or duricrust, over a variety of alumina-bearing rocks. It forms when large amounts of rainfall leach away the more mobile elements in the host rock leaving the relatively immobile aluminium with some silicon, iron and titanium.

It also supplied bauxite for export. • Huntly mines bauxite from within a defined Mineral Lease, known as ML1SA. To date, we have cleared less than 4 per cent of our mineral lease. • As bauxite forms in shallow pods, a constantly moving mining footprint occurs followed by progressive, world-leading rehabilitation.

quantity of mineral ore (called the ‘strip ratio’) is usually greater than one, and can be much higher. For example, if a proposed mining project involves the extraction of 100 million metric tons of mineral ore, then the proposed mining project could generate more than one billion metric tons of overburden and waste rock.

Separation techniques vary widely depending on the mined ore. The transfer of mineral slurries through agitation cells and precipitators requires careful consid-eration of erosion, corrosion and temperature factors. Flowserve pumps can be found at the heart of the most demanding separation processes, including:
