bauxite mining process in Australia
Bauxite is the best material for the production of aluminum metal, is the most important application areas, with more than 90% of its share of world production of bauxite. Australia’s mineral resources are at least 70 species. Among them, bauxite reserves in the world, accounting for 35% of total world reserves. Australia is the world’s largest production of bauxite, alumina, diamonds, lead, tantalum producer, gold, iron ore, coal, lithium, manganese ore, nickel, silver, uranium and zinc also highest in the world.Nonmetallic use primarily for refractory bauxite, abrasive materials, chemicals and high alumina cement raw materials. The amount of bauxite in terms of the proportion of non-metal is small, but the use is very extensive.
bauxite mining processing equipment
Many raw bauxite ore can generally be removed by washing a lot of silica and wet sieving or classification methods to improve the ore grade or grade. Using gravity separation method, such as heavy media beneficiation separable iron bauxite laterite; spiral concentrator or Jig and strong magnetic separator can remove siderite.
Two-stage flotation process: First, the bauxite ore finely ground to 95% passing 200 mesh sieve; positive flotation separation or enrichment of boehmite. The flotation tailings then further pulverized to 95% passing 325 mesh sieve; reverse flotation to remove iron and titanium minerals. If one of the AL2O3 content of about 73% of the concentrate and then pulverized to 325 mesh anti-flotation by its content of TiO2 and Fe2O3, respectively, can be reduced to 2% and 1% or less. Besides using the flotation method can also be selected AL2O3 content of 73% purity bauxite. However, to improve its purity by flotation, high raw material costs.
LM Vertical Grinding Mills
Shanghai SBM vertical mill and ladder type pulverizer is an advanced bauxite grinding machine, grinding at home industry has absolute leading technology advantage.Vertical mill (vertical mill) is to use the structure design is reasonable and reliable, with advanced technological process, drying, grinding, choose powder, ascend into an organic whole, in order to solve the industrial mill, low yield, higher energy consumption. Widely used in glass fiber industry big leaf wax powder production high fineness of grinding; Big production of coal gangue powder powder production; The chemical industry production of all kinds of chemical raw materials of powder production. Non-metallic mineral industry of all kinds of low, medium and high hardness of hundreds of ore mass production of powder preparation.
