INVESTIGATIONS ON FLOTATING BERYLLIUM
The fixation of individual reagents and compounds on minerals was determined by radiometric and chemical methods; the induction time when mineral particles adhered to an air bubble and carried out flotation of some pure minerals, their synthctic mixtures, and particular ores were measured. Fluorspar (albite) and crushed pegmatite were added as a gangue to the composition of the synthetic mixture. The beryllium content in the mixtures was 1%. The beryllium size wse 0.15-0.1 mm, albite or pegmatite size was 0.074 - 0.02 mm. The dependence of Ca/sup 45/ and Fe/sup 59/ sorption on beryllium and fluorspar upon their concentration in the solution and pH of the medium was revealed. It is noted that in weakly-acid, neutral, and alkaline media, a parallel proceeding Fe- hydroxide precipitation process is superposed on the sorption process. The fixing of fatty-acid collectors on beryllium and fluorspar under various conditions was measured. Higher temperatures reduce the fixation of collectors on beryllium. Beryllium activation and fluorspar activation with multivalent metal salts, contained in natural water and waste products of mills, increase the flotation extraction of minerals when using oleic acid as a collector. lt is shown that the use of Na-cationized water for the flotation of synthetic mixtures of beryllium-albite and beryllium ores, makes it possible to considerably increase selectivity of beryllium flotation. Heating the pulp to 85-90 deg C prior to adding the oleic acid and the use of Na-cationized water substantially raise the selectivity of beryllium flotation from synthetic mixtures and ores.
