· Australia is the world's largest producer of bauxite, with the majority used to produce alumina for the aluminium industry. Nonmetallurgical appliions such as refractories, proppants, building materials and pharmaceuticals make up around 10% of bauxite's end uses, however, and many Australian miners are looking at ways to diversify.
The BauxiteAlumina Industry has been a powerful actor on the environmental, social and economic scene in Jamaica since the early 1950s. Impacts of mining and pro cessing on environmental quality have been evident both in the long and short term. The landscape has been damaged, valuable agricultural soils have been replaced by badly eroded skeletal soils capable of sustaining only grass ...
This review article describes the industrial processes of bauxite mining and alumina refining and outlines the physical, chemical, biological, ergonomic, and psychosocial health risks. PROCESS DESCRIPTION: BAUXITE MINING. Bauxite is the principal ore of alumina (Al 2 O 3), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilies, iron .
Bauxite and Alumina Statistics and Information. Primary Commodity Uses: Aluminum is one of the most used metals on the planet, finding roles in transportation, construction, packaging, electronics, and other consumer goods. Gallium is primarily used in integrated circuits and LEDs. The United States is currently reliant on foreign sources ...
· Aluminum Ore: The Political Economy of the Global Bauxite Industry. 29 08 2013. AS: University of British Columbia Press is about to publish a new book on the history of the bauxite industry. As the key component in aluminium production, bauxite became one of the most important minerals of the last one hundred years.
Bauxite residue is a strong alkaline solid waste discharged during the industrial production of alumina [1]. The color of bauxite residue is red because of its rich iron (III) oxides, comprising ...
After the war, because of a number of factors, including the preeminence of the geographicallyclose United States as an economic and military power, and the emergence, at the instigation of the Government, of three companies (Alcan,Reynolds, and Kaiser), each of which needed its own independent source of bauxite, the Jamaican industry was rapidly developed to the point that the island ...
· China imported more than 47 per cent of its bauxite from Guinea last year, but the military takeover in the West African country may force it to turn to Australia for supply.
The Vietnamese government plans to develop an integrated bauxite, alumina, and aluminium industry. In this respect, Vinacomin awarded a contract to Chalieco to engineer and construct the Tan Rai Alumina Refinery in Lam Dong province. Under the original agreement, the Tan Rai Alumina Refinery was to be finished in October 2010; however, at this point in time commissioning has not yet ...

It is also used in appliions such as industrial and medical ceramics, sandpapers, pigments, cosmetics and pharmaceuticals. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global ...
Bauxite Tailings. · Bauxite tailings, also known as red mud, red sludge, bauxite residue, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the ...
Red mud or bauxite residue as a highly alkaline hazardous waste has been incessantly generated from the beginning of the alumina production industry from bauxite ore in the late 19th century. The worldwide inventory of red mud reached an estimated four billion tons increasing at 120–150 million tons annually. This rapid growth rate clearly identifies the development and implementation of ...
