Recovery of aluminium and lithium from gypsum

2015-10-1  Based on the Bayer process, the gypsum residue from the lithium extraction process was digested by alkali to extract its aluminium and lithium. 100% aluminium extraction and 96.4% lithium extraction were recorded at caustic ratio (Na 2 O/Al 2 O 3 molar ratio) of 1.7, digestion temperature of 136 °C and digestion time of 60 min.

Extraction of lithium from primary and secondary

2014-12-1  Extraction of lithium from a zinnwaldite containing waste was investigated by Jandová et al. (2009). The concentrate (1.40% Li) obtained from dry magnetic separation of the waste (0.21% Li) was treated by the gypsum roast method (with CaSO 4 and Ca(OH) 2). About 96% Li was leached out from the sinter made at 950 °C.

OBTAINING Li CO FROM ZINNWALDITE WASTES

2016-4-1  The extraction process of lithium, so-called gypsum method consisted of sintering the concentrate with CaSO 4 and Ca(OH) 2, subsequent leaching of the sinters obtained in H 2O, solution purification and precipitation of Li 2 CO 3. It was observed that almost 96% lithium extraction was achieved if sinters prepared at 950°C

Extraction of lithium from micaceous waste from

2011-11-1  Roasting with gypsum/Ca(OH) 2 produced a lithium extraction of over 90% between 900 and 980 °C. With limestone a peak leach extraction of 90% occurred at 825 °C, with a significant drop-off above that temperature possibly caused by increased crystallinity of eucryptite (Jandova and Vu, 2008). Eucryptite normally requires leaching with strong acid for lithium leach extraction. The mineral is

RECOVERY OF LITHIUM FROM CHINA CLAY WASTE

2019-9-13  A lithium extraction efficiency of about 84% was obtained using gypsum at 1050oC while rubidium extraction was very low at 14%. It was found possible to extract about 97% Li and 16% Rb if the concentrate was roasted with sodium sulphate at 850oC. Processing the concentrate with limestone resulted in very low lithium extraction.

Extraction and recovery of lithium Condorchem

The extraction of lithium brines is carried out by pumping and its concentration by means of adsorption using a selective adsorbent, or by evaporation in shallow pools built for this purpose. The evaporation, in addition to raising the concentration of the salts, causes some of these to be precipitated when saturated.
