subject: Future Market Demand Analysis Of Bauxite [print this page] Owing to the fact that aluminum is the second important metal, next only to iron and steel, in recent more than ten years, under the guidance of the policy of prior development of aluminum industry, this industry has developed rapidly. The output of primary aluminum increased sharply from 0.5247 million tons in 1985 to 1.9007 million tons in 1996, with an average annual increase of more than 12%; the output of alumina increased from 1.025 million tons in 1985 to 2.5462 million tons in 1996, registering an average annual increase of nearly 7%; the output of bauxites increased even more rapidly.Nevertheless, it should be noted that China is a developing country and its per capita consumption of aluminum is low. The world"s per capita consumption of aluminum is 3.29kg, that of USA is 17.3 kg and that of Japan is as high as 33.8 kg, while that of China is only as low as 1.1 kg. With the development of economic construction and the improvement of people"s living standard, China"s demand for aluminum will increase greatly. According to a prediction, up to 2010 the demand for aluminum will reach as high as 2.80 million tons in China. At the end of 1995, although China had a productive capacity of 2.17 million tons of electrolytic aluminum, yet only 1.67 million tons was produced actually (not including miscellaneous aluminum), and therefore the gap between the productive capacity and the expected demand remains to be covered.Furthermore, it should be noted that most of the bauxite ores in China are composed of high-aluminum, high-silicium and low-iron monohydrate diaspore ores, which are characterized by low exsolubility, low Al/Si ratio, difficulty in processing, high energy consumption, and low cost effectiveness. At the end of 1995 although six plants of alumina in China had already a production capacity of 3.55 million tons, the actual output, however, was only 2.24 million tons. According to the estimation that two tons of alumina are required for producing one ton of aluminum ingot, up to 2010 there must be 5.60 million tons of alumina for producing 2.80 million tons of metallic aluminum, so the gap between the production capacity (or output) of the existing plants of alumina and the actual demand remains to be covered.As the professional manufacturer of complete sets of mining machinery, such as mobile crushing station,cement production line, 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.China is more or less abundant in bauxite resources, and at the same time is possessed of rich coal and hydroelectric power. These are the favourable conditions for development of aluminum industry in China. With the completion of several large-scale hydroelectric power stations in the Northwest of China and putting some new bases of aluminum industry into production, the output of aluminum in China will be increased greatly.At the same time, when new bases of aluminum industry are constructed, efforts should be made to intensify technical transformation and operational management of old enterprises, and to achieve the production quotas with products up to the required standards, while lowering the productive cost. This is the indispensable prerequisite for the development of aluminum industry in China.Considering that most of explored bauxite reserves in China are unsuitable for economic opencut mining, and there are very few low-silicium and high-grade bauxites, the geological survey should be intensified to look for more high-quality bauxites , especially idrargillites.Owing to the fact that the quality of bauxites in China suffers from an inherent inferiority, in order to improve the economic performance of alumina factories, it is necessary to import some parts of high-quality idrargillite ores from abroad for a certain period of time to come so as to guarantee a smooth development of China"s aluminum industry, and China"s effective participation in the competition in the international market.iron ore concentrator:http://www.hx-crusher.com/ore_beneficiation.html mobile jaw crusher:http://www.hx-crusher.com/stone_crusher.html
