Bauxite refers to the ore that is industrially usable and composed of gibbsite, boehmite or diaspore as the main mineral. The application fields of bauxite are metal and non-metal. In terms of metal, bauxite is the best raw material for the production of metal aluminum, and is also the most important application field, accounting for 90% of the world's total bauxite production. the above. The proportion of bauxite in non-metallic applications is small, but its use is very extensive, mainly for refractory materials, abrasive materials, chemicals and high alumina cement raw materials.
The world's bauxite reserves are huge, but China is facing depletion.
According to the preliminary estimates of the US Geological Survey, the world's bauxite resources in 2002 were about 55 billion to 75 billion tons, mainly distributed in South America (33%), Africa (27%), Asia (17%), and Oceania ( 13%) and other regions (10%).
According to industry analysts, if the world's alumina production is estimated at 60 million tons per year, the annual consumption of bauxite reserves is 300 million tons, and related industries such as fused corundum and high-aluminum cement consume some more, and the annual consumption of reserves is 400 million. Tons, the world has reserves of 22 billion tons, and its guarantee period for the aluminum industry and related industries can reach more than 50 years. In addition, in recent years, the investment in bauxite exploration in various countries is gradually increasing. In general, the global bauxite resources will not be in short supply within a certain period of time.
According to the exploration results, by the end of 2002, China's bauxite reserves of 2.9 billion tons of reserves (reserves 700 million tons, resources of 2.2 billion tons), ranking eighth in the world, accounting for about 10% of the world's total reserves. China's bauxite distribution is highly concentrated. The reserves of Shanxi, Guizhou, Henan and Guangxi provinces account for 90.9% of the country's total reserves (41.6% in Shanxi, 17.1% in Guizhou, 16.7% in Henan, and 15.5% in Guangxi).
However, compared with the huge reserves of bauxite in the world, China's bauxite resources are relatively scarce. Relevant experts pointed out that according to the estimated reserves, the reserves of bauxite resources in China are not optimistic. Some experts even predict that China's bauxite resources will be basically exhausted by 2015.
Ways to Solve the Scarcity of Bauxite Resources in China
In recent years, aluminum is one of the fastest growing metals in China, and China has become one of the world's largest aluminum producers and consumers. The industry believes that due to the poor quality of China's bauxite mines, high production costs and low market competitiveness, the import of bauxite-related products will increase rapidly year after year, and China's dependence on foreign countries has increased significantly. In this regard, relevant departments and enterprises in China should actively seek solutions. At present, the main ways are as follows.
First, because China's bauxite resources are scarce, recycling recycled aluminum resources is very urgent. On February 22, the National Development and Reform Commission issued the “Guiding Opinions on Further Strengthening the Development and Utilization of High-Aluminum Fly Ash Resourcesâ€, and proposed a number of measures such as setting up entry barriers and strict project approval to strengthen the development of high-aluminum fly ash resources. The introduction of the "Guidance Opinion" can open up the source of aluminum resources, maximize the value of resources, maximize the value of high-aluminum fly ash resources, enhance the capacity of aluminum resources, and promote the sustainable development of the aluminum industry.
Second, we should quickly establish a resource-economic partnership with neighboring countries to maximize the sharing of overseas resources. This is the fundamental way to solve the shortage of bauxite resources in China, and it is also the most effective way.
Some experts pointed out that the mineral deposits in Central Asia, South Asia, Latin America and Africa are ideal areas for the development of mineral resources outside China, such as bauxite mines in Vietnam and Laos. The estimated reserves are 8 billion tons and 2 billion tons respectively. 600 million tons of bauxite resources were also found. Therefore, the establishment of the "Central Asian Resource and Economic Circle" and rationalization of resource development and supply channels in neighboring countries are the vital interests of safeguarding China's resource needs.
Taking Chinalco as an example, in recent years, Chinalco strives to obtain bauxite resources at home and abroad. Chinalco has been committed to seeking cooperation with Australia, Vietnam and other countries. Xiong Weiping, chairman and CEO of Chinalco, said that in 2011, Chinalco will continue to promote overseas projects such as bauxite in Southeast Asia and Simandu in Guinea.
In summary, our bauxite resources are in short supply. If we do not accelerate the pace of improvement, it will affect the development of China's aluminum-related industries. Therefore, China should increase the recycling and comprehensive utilization of bauxite resources, especially to strengthen overseas The cooperation makes full use of the abundant bauxite resources in the world to make up for the shortage of bauxite resources in China.
