Alumina Ceramic:

China has abundant bauxite resources. So far, it has proven reserves of 2.3 billion tons, ranking fourth in the world, and has the resources to develop the alumina industry. According to incomplete statistics since 2004, the number of alumina investment projects announced in China has reached 27, with a total scale of 16.041 million tons. Even if we do not consider the use of foreign bauxite resources and projects to invest and set up factories overseas, the total scale will reach 28.941 million tons. At the end of 2006, Chinalco's alumina production was 9.52 million tons. In addition to the scale of alumina already under construction, there is also a total of 1.92 million tons of alumina to be built in the country, which is close to all the proposed (expanded) alumina projects in foreign countries. The rapid development of the alumina industry is different from the previous low-level redundant construction, but on the scale and high level, optimizing the structure and greatly improving the overall level and competitiveness of China's alumina industry. However, if this investment boom continues to expand in a disorderly manner, it will inevitably lead to a relative surplus of products.
There are more than 40 alumina enterprises in China, and the capacity built and under construction has reached more than 43.5 million tons/year, of which the domestic bauxite capacity is 32.5 million tons/year. In 2010, the national alumina output was 28.96 million tons, making it the world's largest alumina producer.
