Spodumene is the main raw material for extracting lithium. Lithium is used in atomic energy industry, aircraft, missile and aerospace industry and metallurgical industry to make light alloys, wear-resistant alloys and rare metal reductants. Spodumene can be used as raw material for producing glass and ceramics. Chemical products such as lithium carbonate can be prepared by reacting spodumene with carbonate solution after calcination. Lithium carbonate is used to produce ceramics, medicines, fluxes, aluminum electrolytic batteries and lithium chemicals. Lithium chemicals are used in bleaching, hydrogen production, oxygen production, catalyst, vitamin synthesis and the production of extremely cold and heat-resistant oils and fats. The quality of industrial spodumene concentrate is: Li2O >；; 3.5%~6%，Fe2O3≤3%~4.5%，MnO≤0.5%~ 1%，P2O5≤0.5%~ 1%，R2O≤4%。
