Actively carry out research on alumina extraction technology from low-grade bauxite, high-sulfur bauxite, high-aluminum fly ash and other resources, and implement strategic reserves for the technology. Break through the technical bottleneck of high-sulfur bauxite desulfurization industrialization as soon as possible to ease the supply pressure of low-sulfur bauxite;
achieve breakthroughs in the comprehensive utilization technology of bauxite with A/S less than 3 to expand the amount of available resources and extend domestic bauxite services years, improve the utilization rate of resources; encourage the research and development of alumina production technology from high-aluminum fly ash, form a technology that can be industrialized, and implement strategic reserves.
