Flotation of anions using cationic surfactants. Pt. 4. Flotation of molybdates, perrhenates and chloroaurates from solutions of some electrolytes

A study of the effect of Cl-, NO3- and SO42- ions at concentration 0.0001 to 0.05 kmol/m3 on the efficiency rate and enrichment ratio of flotation of perrhenate, molybdate and chloroaurate ions at concentration 5.10-5 kmol/m3 using the cationic surfacant cetyldiethylammonium hydrochloride - CDAHC and radioisotopes Mo-99, Re-186, and Au-198, demonstrates that under the experimental conditions even a 1000-fold excess of these anions has no complete stemming effect on the process. Only the lowering of the rate and of efficiency is observed, while the enrichment ratio in most cases grows with increase of the introduced electrolytes concentration. (author)
