Experimental Study on a New Depressant LJ for Flotation Separation of Cu-S
A copper sulfide ore in Guangxi is adopted lime high alkali process in copper and sulfur flo-tation separation.In view of the problems of high slurry viscosity,more foam slime entrainment and difficul-ty in obtaining high grade copper concentrate products,a new inhibitor LJ is used instead of lime to carry out experimental research.The results show that the copper concentrate with copper grade of 24.75%and copper recovery rate of 92.64%is obtained by the closed-circuit test of one roughing,two cleaning and two scavenging under the condition of natural pulp pH by new inhibitor LJ.The copper grade of copper concen-trate is much higher than that of the original lime high alkali process copper concentrate copper grade,and the copper recovery rate is also slightly improved.The efficient separation of copper and sulfur is realized,which can provide reference for the separation of copper and sulfur in similar copper sulfide ores.
