In recent years, with the continuous expansion of alumina scale, the demand for bauxite has increased rapidly, increasing to more than 100 million tons in 2011 and to more than 200 million tons in 2018. Due to the lack of domestic resources and poor endowment, China's aluminum industry largely depends on imported resources for production. Over the past decade, China's ore use structure has changed significantly. Before 2005, China mainly imported alumina directly, and its dependence on bauxite was low; As China's alumina production capacity using imported ore continues to expand, China's demand for imported ore continues to increase. In 2021, China's alumina production capacity will be 90.15 million tons / year, of which the alumina production capacity using imported ore will be 42.1 million tons / year, accounting for 46.7%; The alumina production capacity of domestic ore is 48.05 million tons / year, accounting for 53.3%. The demand for imported ore is 117 million tons and the demand for domestic ore is 110 million tons. The demand for imported ore accounts for 52% and the demand for domestic ore accounts for 48%.
The production area is mainly distributed around bauxite resources, with distinct regional characteristics. China's alumina production is mainly distributed in 8 provinces and autonomous regions of Shandong, Shanxi, Henan, Guangxi, Guizhou, Chongqing, Yunnan and Inner Mongolia. Among them, enterprises in Guizhou and Yunnan mainly produce domestic mines; Enterprises in Shandong and Chongqing mainly produce imported ores; The production capacity of enterprises in Shanxi, Henan, Guangxi and Inner Mongolia using imported minerals has also increased year by year in recent years.
One is to use imported ore for production by taking advantage of the port. These production capacities are mainly distributed in Shandong, Guangxi and Inner Mongolia. At present, most alumina projects under construction or to be built are in this mode; The other is through process transformation, so that the production capacity originally using domestic ore begins to use imported ore for production, which is mainly concentrated in Henan, Shanxi and Chongqing. According to statistics, since 2018, the transformed imported minerals can reach 12 million tons / year, accounting for 28.5% of the imported mineral production capacity.
After years of large-scale mining, domestic ore resources can no longer support the huge aluminum industrial production. At the same time, the normalization of environmental protection and high pressure also greatly restricts the mining activities. In the future, enterprises in Shanxi and Henan will continue to increase the production capacity of imported ore. It is reported that a company will continue to increase the use of imported ore capacity through technological transformation. The demand for imported ore of its alumina plant is expected to reach 12 million tons in 2022, an increase of about 4 million tons compared with 2021.
To sum up, China's demand for imported bauxite is expected to increase by about 20% year-on-year in 2022.
