| Abstract: |
| A tellurium tailings is content of high sulphur, but the mineral composition is very complex and the sulfide minerals is depressed by lime and sodium sulfite, which increases the difficulty of flotation. on the basis of a floating tellurium tailings process mineralogy research. The result of single flotation as compared with magnetic separation-flotation shows that adding magnetic separation does little to improve the pyrite ore dressing indexes. Through the condition experiment, the optimal reagent system had be determined after one stage roughing, two stage scavenging,one stage cleaning, and eventually getting the sulphur concentrate grade is 40.39% and the recovery is 90.69%. |
