Bauxite is an aluminum-rich minerals, chemical or biochemical rock. The main mineral component is diaspore , boehmite, gibbsite. Alumina silicate minerals are weathering after intense heat. It will produce dissolved alumina, , moving into the sea from the lake basin sediments.
Bauxite processing production process
Because bauxite is mainly used in the refractory industry, which usually refers to calcined bauxite Al2O3> = 48%, so the following bauxite powder production and processing technology has become the mainstream market.
1. Raw material is fed into the burner via high temperature calcination, Part of material can also adopt drying method.
2. After being crushed by small jaw crusher, or hammer crusher, calcined bauxite will be fed into the mill.
3. After the crushed material enter the mill production systems, entire milling, separating and other operations processes are finished inside the mill automatically. The operating workers should take close notice on Electrical cabinet meter data.
4. Qualified bauxite powder will discharge via the discharge valve, then packing into bags.
SBM MTM, MTW trapezium type roller mill, LM vertical milling machine and SCM ultrafine grinding powder machine are very popular in bauxite process.
Widely used in non-metal, cement plant, construction, sand metallurgy.
Widely used in paint, paper, paint, rubber, plastics, fillers, cosmetics, chemicals and other industries.
Alumina and bauxite production is increasing in global market. The research analysis shows that Australia has become the world's largest producer of bauxite. In 2011, annual output has reached 70 million tons, while alumina production in Asian countries including China, Indonesia, India also get gradually increase, accounting for 45% of global supply, 10 years ago, it is only 16%. Domestic demand is pushing China bauxite manufacturers to look for foreign ore, or in the form of a joint venture or acquisition bauxite open up foreign markets, such as Australia, Guinea, Ghana, Indonesia and Fiji and other countries.
