Extraction of lithium, rubidium and cesium from

2020-1-1 · Up to 98.70% Li, 97.27% Rb, 98.40% Cs were selective extracted with additive of Na 2 SO 4 and CaCl 2.. Selective extraction was based on ion-exchange between alkali metals from mineral and Na + from Na 2 SO 4, Ca 2+ from CaCl 2.. HSC was used to predict the effect of temperature and ore/Na 2 SO 4 /CaCl 2 mass ratio.. Si and Al in the mineral promote the extraction process.

Study on Extraction of Vanadium from High Acid

A new extractant [email protected] was used to directly extract vanadium from high acid leach solution of stone coal. The effects of acidity and Eh of feed, time, phase ratio and temperature on the extraction of vanadium were investigated. The extraction distribution isotherm was also obtained. The results showed that the extraction of vanadium reached 98% in single stage with A/O ratio of 1:1 at 35~45 ...
