Extraction of lithium from its ores - 911 Metallurgist

2016-5-24  N the early days of the lithium industry most of the production was from lepidolite, zinnwaldite, and amblygonite. Nearly all the early extraction processes described in the literature involve heating the finely ground mineral with sulphuric or hydro- chloric acid. On subsequent water leaching most of the bases present in the mineral (especially alumi- num) are dissolved as sulphates. As a result, the leach solution required extensive chemical purifica- tion before the lithium could be precipitated as car- bonate. Following the remarkable growth of the lithium industry to its present size, zinnwaldite and amblygonite ores must be considered of minor im- portance only. Attention is now focused on spodu- mene, abundant enough in North America to be a major source of supply, and there are important supplies of lepidolite and petalite in Africa. The extraction processes described below all apply to spodumene, although several will also operate on other lithium

2012-7-18  The most important processes for the extraction of lithium from lepidolite are the sulfate acid and the lime methods (Distin and Phillips, 1982). However, the extraction of lithium by sulfate acid method uses high concentration acid and the purification procedure is complex. The lime process uses limestone and requires a large amount of energy.
