Study on the predicament and sustainable development of the alumina smelting industry in China

On the basis of a comprehensive review of the production and technology status of China's alumina industry, the main contradictions and challenges in the development of China's alumina industry in terms of resources, energy and environmental governance are analyzed, and the production cost is compared and analyzed worldwide. It is believed that the main factors restricting the sustainable development of alumina industry in China are the lack of sufficient high-quality bauxite resources in China, the production technology needs to be further optimized, and the generated solid and hazardous waste is difficult to realize harmless and resource utilization. In this regard, this paper puts forward the strategy for the sustainable development of China's alumina industry, that is, strictly control the disorderly and rapid expansion of production capacity and reasonable layout, optimize the resource and energy supply structure, implement the industrial development strategy of high quality, energy saving and low consumption to improve the core competitiveness, and accelerate the realization of the standard discharge and resource utilization of waste gas, wastewater and solid waste. The results of this paper are of great significance to the strategy of industrial structure adjustment and sustainable development of alumina industry in China.
