- W2391077228 abstract "Using several ammonium( amine) salts as activators,the sulfide flotation behaviors of refractory oxidised copper ores in Huidong have been studied. The results showed that ethylene diamine phosphate,ammonium sulfate,ammonium chloride,ammonium bicarbonate and diammonium phosphate have significant activation to sulfide flotation of oxidised copper ores. When using single activator,the performance of ethylenediamine phosphates was the best,while using a composite one,the performance of ethylenediamine phosphate and ammonium bicarbonate combination was the best. The activation effect of composite activator was better than that of single. When ethylenediamine phosphate and ammonium bicarbonate were combined with ration 1∶ 3 and dosage 480 g / t,a final copper concentrate with grade of 19. 01% and recovery of 83. 31% were obtained. Compared to the direct sulfide flotation,the concentrate grade was raised by 4. 05% and the recovery was increased by 12. 42%." @default.
