The role and distribution of world bauxite

The importance of bauxite resources

Bauxite resources and energy is to determine the basic conditions for the construction of the aluminum industry, aluminum industry is the determining factor.

1) aluminum materials. Mainly gibbsite, a boehmite or diaspore of water-based aluminum ore to produce alumina, alumina more than 90% are primary aluminum production of metallurgical alumina, 10% of alumina chemicals.

2) high alumina cement. High alumina calcium aluminate cement is the main

3) refractory. Can be used for high-alumina refractory bauxite, cast bricks, ordinary bricks, etc., can also manufacture mullite. hammer mill for sale

4) Chemicals and other products of the material. Bauxite production of sulfuric acid can be aluminum, aluminum chloride, sodium aluminate, etc. Also the manufacture of artificial corundum, grinding wheel, abrasive, sandpaper, etc.

5) grade bauxite can be used for sugar, oil and other bleaching agents.

6) can be made high-speed road materials.

Distribution of the world's bauxite reserves

First discovered the world's bauxite began in 1821. Prospecting and exploration work around the world to prove, the world's bauxite resources are widely distributed, more than 50 countries across five continents, rich resources, huge reserves. End of 2002, the world's bauxite reserves of 22.89 billion tons, total reserves of about 61.2 billion tons, by expanding the scope of prospecting, bauxite reserves can be increased to 75 billion tons. The world's bauxite reserves of the richest countries are Guinea, Australia, Vietnam, Brazil, Jamaica, 5 country's total reserves of 16.15 billion tons, accounting for 70% of total global reserves, five national reserves 44.3 billion tons, accounting for about 72% of total reserves. The end of 2002, China's 2.5 billion tons of bauxite reserves, among the world's No. 6, the total reserves of the world's 4.l%; reserves of 539 million tons, ranking the world's first nine, accounting for 2.4% of total global reserves . gold stamp mill manufacture

Characteristics of the world's bauxite reserves resources

1) abundant, high degree of safety and security. Static reserves of about 146 mining service life, the basic reserves of about 209 years, the static guarantee period, even if the amount of growth in the next 20 years, 1 fold, in the foreseeable 21st century world reserves of bauxite resources to ensure demand. mobile cone crusher for sale

2) distribution is extremely uneven. The world's bauxite resources in the country with more than 50, but ranked the world's top five countries accounted for reserves and reserves for more than 70% of the total, the top 10 countries accounted for 85% of the world's resources more.

3) the changing distribution patterns. Following the 1960s, Australia's reserves of bauxite to become big and the bauxite and alumina 70 years producing countries since the 1980s in West Kalimantan, Indonesia, Venezuela Luosipixi melon, Saudi Arabia slaughter than other places but pull some important deposits have been found, also found in southern Vietnam's bauxite into a giant mining, Laos has considerable resource potential, Venezuela has become the world's most important one of bauxite resources.
