BAUXITE MINING The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the form of aluminium hydroxide. About 90% of global bauxite supply is found in tropical areas.
Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase
Widely used in construction,decoration and industry Various kinds of raw material : aluminum alloy such as 6063,6061,6060,6082,7075.Surface treatment: mill finish, anodizing, powder coated, electrophoresis, wooden line finish.
There are several minerals available in the world from which aluminium can be obtained, but the most common raw material is bauxite. Bauxite is a mineral made up primarily of aluminium oxide mixed with some other minerals. Bauxite is regarded as high quality if it contains more than 50% of aluminium
Mining Safety. Operating safely is a core value, and our employees embrace a culture where we protect one another every day. We are proud to be recognized nationally for our commitment to metal mining safety. Doe Run and our predecessors have earned the National Mining Association’s Sentinels of Safety award a combined 28 times since 1971.

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. It contains a mixture of oxides like aluminium hydroxides, hydrous aluminium oxides, and minerals like gibbsite, boehmite and diaspore including some clay minerals.
Dec 12, 2019· Properties and Raw Materials. Aluminum is the third-most plentiful element in the earth’s crust, and it makes up 8% of the planet’s soil and rocks. In nature, aluminum is found only in chemical compounds with other elements, such as sulfur, silicon, and oxygen.
Aluminum smelting project in Canada. Marubeni holds a 13.3% stake of the Alouette Aluminum Smelter in Canada, which has the largest production capacity in North America. The aluminum smelter runs on hydro power and operates with minimal environmental impact, and also succeeds in
Metals players, whether in steel, aluminum, copper, or other base metals, must shape strategy and drive performance in an environment of unprecedented volatility and flux. Metals value chains are “slivering” into distinct slices, each with its own economics, while radical shifts in global supply-and-demand patterns mean producers must adapt

ALVANCE is the newly formed international aluminium vertical, part of the GFG Alliance, which brings together assets across the aluminium supply chain from raw materials through to
Nov 05, 2020· Historically, the alumina market was priced as a percentage of the outright aluminium price on the LME, but physical contracts have since changed to being based on price reporting agency indices because there can often be a disconnect between the aluminium prices and raw materials. Currently the alumina index is at 14% of the LME three-month price.
Aluminium, the most common metal in the earth’s crust, is lighter than copper, steel or brass, resists corrosion and readily conducts electricity and heat. It is non-sparking and non-magnetic, and can be recycled indefinitely. When combined with zinc and magnesium, aluminium is stronger
