Description	Rubidium was recovered from lithium-contg. soln. from processing zinnwaldite, (KAl(Fe,Li)(Si3Al)O10F2), conc. after Li2CO3 crystn. as a mixt. of rubidium and potassium alums (RbAl(SO4)2.12H2O and KAl(SO4)2.12H2O). The course of individual reactions aiming at rubidium alum sepn. from carbonated solns. contg. potassium as a main contaminant was studied on synthetic solns. Before the alum pptn., the original carbonated soln. was converted to sulfate soln. Rubidium recovery efficiency at least 95% was achieved if the amt. of the pptn. agent (Al2(SO4)3) ranged between 3.5 and 4.0 multiples of stoichiometric amt. related to rubidium concn. in the processed soln. Under such conditions, ppts. obtained contain between 4.10 and 3.62% Rb and from 6.02 to 6.25% K and consist of on av. 24% rubidium alum and 75% potassium alum.
