| Abstract Scope |
There are a large amount of spodumene deposits in Ganzi Prefecture, Sichuan Province, China. This project directly uses spodumene ore as raw material, produces aluminum-silicon alloy by electrothermal method, and then separates aluminum and silicon by three-layer liquid method to obtain 3N high-purity silicon. Liquid aluminum is made into aluminum powder, which is transported to the place where hydrogen is required hydrogen production is carried out; the smelting dust containing 20~30% of lithium oxide is collected, and the monohydrate lithium hydroxide is prepared by the alkaline method of micro-pressure heating, and the metal lithium is produced by the electrothermal method. Hydrogen, metallic lithium and high-purity silicon are directly produced from spodumene ore, and the resources are comprehensively utilized. |
