subject: Availability And Consumption Analysis Of Bauxite [print this page] In recent years the aluminum consumption of China has been increased rapidly. According to statistics, while the consumption of primary aluminum was 0.8610 million tons in 1990, it doubled in 1995, reaching 1.8749 million tons, and went up as high as 2.0331 million tons in 1996.China"s production of refined aluminum was 0.8548 million tons in 1990, doubled in 1995, reaching 1.8697 million tons, and increased to 2.1786 million tons in 1997.The comparison between production and consumption indicates that, in recent years the aluminum production can not meet the consumptive demand on the market, with the inadequate part relying upon imports. The volume of net import of aluminum and aluminum alloys (volume of import minus volume of export) was 6,646 tons in 1990, while it reached 196,615 tons in 1995, and it was further increased to 256,084 tons in 1996. The volume of net import of aluminum materials also increased greatly, from 32,768 tons in 1990 to 212,046 tons in 1997 (Table 3.9.4).As the professional manufacturer of complete sets of mining machinery, such as spiral separator,Sand making machine, 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.It should be noted that, the bauxite deposits of China are mainly composed of monohydrate diaspore ores. It is not very cost-effective to produce alumina from such ores due to their high energy consumption in smelting. Furthermore, the production capacity is not enough, so the output of alumina can not meet the demand for the production of electrolytic aluminum, and in this case a large volume of alumina has to be imported every year. According to the statistics the net volume of alumina import increased from 32,768 tons in 1990 to 1,081,634 tons in 1997 (Table 3.9.4).Table 3.9.4 Statistics of import and export of bauxites and relevant products(t)The import and export trade of aluminum and aluminum raw materials of China is effected by the international aluminum market and the domestic economic construction, and varies greatly. Generally speaking, it is characterized by the export of more raw materials, and the import of more processed and smelted products.artificial sand washer:http://www.hx-crusher.com/sand_washer.html cement rotating dryer:http://www.crusher-machine.com/24.html
