In recent years, China's aluminum processing industry is facing problems such as gradually tightening policies, declining profitability and continuous trade friction. Accelerating transformation and upgrading has become the top priority for the development of aluminum processing industry. With the state's supply side structural reform of the aluminum processing industry and the technological progress of the aluminum processing industry, the aluminum smelting industry is developing to high quality. 1、 Industrial chain the processing industrial chain of aluminum industry refers to the whole industrial chain in which alumina is extracted from bauxite, then made into electrolytic aluminum, then processed into various aluminum materials, and finally applied in downstream products. The aluminum processing industry chain can be divided into three links: upstream raw materials, midstream aluminum profile processing and downstream industry application. Data source: China Commercial Industry Research Institute II. Upstream analysis: the upstream of aluminum processing industry is bauxite, which is decomposed into electrolytic aluminum after producing alumina. Electrolytic aluminum undergoes electrochemical reaction under the action of direct current and precipitates metal aluminum at the cathode. 1. Bauxite the world is rich in bauxite resources with huge reserves. At present, more than 270 kinds of aluminous minerals have been found in the world, of which the most important aluminous ore is bauxite. According to statistics, the global bauxite basic resource reserves are close to 30 billion tons, the output is close to 300 million tons, and the retention period of basic resources is close to 100 years. The global bauxite resources are very rich, but the distribution is extremely uneven. Among them, the reserves of China and Australia account for nearly half of the global reserves. Data source: compiled by USGS and China Commercial Industry Research Institute, China's bauxite output shows a fluctuating growth trend. In 2016, China's bauxite mineral output was 65 million tons. In 2018, China's bauxite output increased to 79 million tons, with an average annual compound growth rate of 10.2%.

Data show that China's alumina output reached 73.132 million tons in 2020 and 39.281 million tons in the first half of 2021, a year-on-year increase of 11%. Data source: regional distribution of alumina industry in the database of China Commercial Industry Research Institute. From the perspective of regional proportion, the alumina output in East China was the highest in 2020, accounting for 38.3%, followed by North China, accounting for 25.3%. Central China, South China and accounted for more than 10%, 13.8% and 12.9% respectively. Data source: large database of China Commercial Industry Research Institute 4. Electrolytic aluminum electrolytic aluminum is the aluminum obtained by electrolysis, which is mainly used to produce aluminum processing materials for various purposes. Data show that in 2020, China's electrolytic aluminum output reached 37.08 million tons, and in the first half of 2021, China's electrolytic aluminum output reached 19.635 million tons, a year-on-year increase of 10.1%. Data source: according to the database of China Commercial Industry Research Institute, China's electrolytic aluminum consumption showed an overall growth trend from 2015 to 2019. In 2019, although the growth rate of electrolytic aluminum consumption decreased, it still increased by 2.4% compared with 2018, and the consumption reached 36.72 million tons. It is estimated that the consumption of electrolytic aluminum in China will reach 39.87 million tons in 2021.
