subject: Available Value Of Bauxite In China [print this page] Actually the industrially usable ores, mainly composed of idrargillite, boehmite, or diaspore, are referred to as bauxite. It is used in both metallic and nonmetallic fields.Bauxite is the best raw material for producing metallic aluminum, and this is the major field of its application, for more than 90% of the total world bauxite output is used for this purpose.In the field of nonmetallic usage, it is used as raw material for production of refractory and abrasive materials, chemicals and high-Al cement. Though the proportion of bauxite used in the nonmetal field is small, its application, however, is very wide. For example, in the respect of chemicals, such products, as aluminum compounds can be used for paper making, purification of water, ceramics and petroleum refining; active aluminum oxide can be used as accelerant, catalytic carrier, and physical adsorbent for discolouration, degasification, dehydration, deacidification and desiccation in chemical, oil refining and pharmacentical industries; the aluminum chloride produced with r-Al2O3 can be used for organic synthesis of dyestuff, rubber, medicine and petroleum; 3%~5% Al2O3 in glass composition can raise its melting point, viscosity and intensity; its abrasive material is used for production of high-quality grinding wheel and polishing powder; its refractory material is indispensable for constructing furnace for industry.As the professional manufacturer of complete sets of mining machinery, such as stone crusher,cone crusher, Henan Hongxing is always doing the best in products and service.china cement mills:http://www.crusher-machine.com/23.html.Primary jaw crusher:http://www.hxjqchina.com/product-list_11.html.Aluminum is the second major metal next only to iron and steel. In 1995 per capita consumption of the world reached 3.29 kg. Because of its low specific gravity, good electrical and thermal conductivity, being easy of machining and other excellent properties, aluminum is widely used in various sectors of national economy. Nowadays a majority of aluminum is used in construction, communications and transportation, and packing departments throughout the world, accounting for more than 60% of its total consumption.The present section deals mainly with the bauxite used for producing metallic aluminum and its deposits. As concerns the bauxite used for producing refractory clay and its deposits, they will be discussed in the section "refractory clay" of the Nonmetallic Minerals.china jaw crusher:http://www.crusher-machine.com/1.html ore flotation equipment:http://www.hxjq-crusher.com/34.html
