Extraction of lithium and aluminium from bauxite mine tailings by …
At the same time, the silicon content in tailings is also very high, which hinders the extraction of aluminium from tailings. However, it has been found that lithium is obviously enriched in tailings at contents much higher than the average content in bauxite, and it has been found that lithium mainly exists in clay minerals (Zhang and Zhang ...
