The extraction rates of cesium and rubidium were 99.81 and 98.09%, respectively, and 19.31% of potassium was co-extracted in the organic phase after five-stage countercurrent extraction.
Among them, lepidolite, K (Li 2-x Al 1+x )Al 2x Si 4-2x O 10 (F,OH) 2, is a layered aluminosilicate mineral that exhibits variable compositions because rubidium and cesium are present as isomorphous substitutions with potassium hosted in the lattice of lepidolite (Liu et al., 2019; Yan et al., 2012).
Overview -- Rubidium is a soft, ductile, silvery-white metal that melts at 39.3 ?C. One of the alkali metals, it is positioned in group 1 (or IA) of the periodic table between potassium and cesium. Naturally occurring rubidium is slightly radioactive. Rubidium is an extremely reactive metal--it ignites spontaneously in the presence of air and decomposes …
Crystals of anhydrous K, Rb, and Cs hypophosphites have been obtained. The structures of these compounds were determined by X-ray diffraction analysis.
