铵（胺）盐对孔雀石硫化浮选行为的影响
Impact of Ammonium (Amine) Salts on Behavior of Malachite Sulfid e Flotation
摘要
Abstract
Abtsract:Using several ammonium ( amine ) salt as activators, the sulfide flotation behaviors of malachite were studied in RK/FGC-50 groove type flotation machine.The results showed that eth-ylenediamine phosphate ammonium sulfate ,ammonium bicarbonate,ammonium chloride,ammonium nitrate,ammonium fluoride, ammonium carbonate had activation on sulfide flotation of malachite . When using single activator,the performance of ethylenediamine phosphates was the best,when u-sing 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 the pH=10,ethylenediamine phosphate and ammonium bicarbonate were combined with the molar mass ration of 1:10 and the dosage was 1.1 ×10-4 mol/L,The dosage of sodium sulphide was 5 ×10-4 mol/L and isoamyl xanthate dosage was 1 ×10-3 mol/L,the malachite were gained with the recovery of 67.67%.Compared to the direct sulfide flotation,the recovery was increased by 25%.关键词
