Hardness: a combination of minerals
Composition: Alumina Water
Special quality: white, gray, yellow, red
Place of origin: near Arles in S France
Functional use: Bauxite is widely applicated in both metal field and nonmetal field. Bauxite mine is the best material for producing aluminum. In nonmetal field, bauxite is mainly used as refractories, abrasives, and the raw materials for high alumina cemen.
Introduction to Bauxite
Bauxite mine is actually kind of ore minerals collectively formed mainly by gibbsite, a boehmite or a diaspore which can be used in the industry. Bauxite mine can be used widely in many industries among which the most important is to be used for refining aluminum in aluminum Industry, refractory and abrasive materials, and raw materials for high alumina cement. The quality requirements to bauxite mining vary according to their different applications.
Guinea is the world’s largest supplier of bauxite mine which has the world’s approximately 1 / 3 of the bauxite mine reserves. Guinea, with its rich mineral resources has attracted many international bauxite mining companies. The other countries which also have large amount of bauxite mine reserves are Australia, Brazil, and Jamaica. With so much bauxite mine, it’s very important for bauxite mining and bauxite crushing or bauxite grinding with high efficiency. As the professional stone crusher manufacturer and grinding mill manufacturer, NFLG has exported large amount of bauxite crusher and grinding mill plants to the bauxite mining countries.
Bauxite Application in industry
Bauxite is widely applicated in both metal field and nonmetal field.
As we all know, aluminum is the world’s second most important metal after steel. As the aluminum is of small proportion, good thermal conductivity, easy mechanical processing and many other good properties, bauxite mining has been widely used in national economic departments. Bauxite mine is the best material for producing aluminum which is also the most important application areas for bauxite, The amount accounts for more than 90% of the world’s bauxite mining.
In the nonmetal field, bauxite is mainly used as refractories, abrasives, chemicals and the raw materials for high alumina cemen. Although the amount of bauxite in the proportion of non-metallic area is small, there is a wide range of uses. Bauxite mine is just indispensable in these areas.
Extraction of aluminum industry from bauxite mine
The general process of extracting aluminum in industry is as follows: First you need to extract alumina from bauxite. Then the alumina will be changed to aluminum by electrolysis. Now there are mainly three methods for alumina production which include sintering, Bayer and joint method.
However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose NFLG crusher or NFLG grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple. Generally we use the professional NFLG mining equipments for bauxite crushing. As the leading stone crusher manufacturer and grinding mill manufacturer, NFLG has also been closely following the bauxite mining at home and abroad. NFLG has manufactured large amount of mining equipments to global countries, such as jaw crusher series, impact crusher series, cone crusher series and the grinding mill series, etc. NFLG mining equipments have been exported to more than 130 countries which are widely applied in mining industry including the bauxite crushing. For decades, NFLG has always continued to innovate in the development, production, sales, and service sectors.
