| Abstract: | To comprehensive recovery of sulfur and iron from the tailings of lead-zinc ore,the properties and technological mineralogy of the tailings were studied.The tailings contained refractory pyrrhotite and the contents of sulfur in iron concentrate were excessive.Using the combined recovery process of floating-magnetic separation-flotation,adding the activator to collect refractory pyrrhotite in flotation,iron concentrate of Fe 58.04% and S 0.547% was obtained,and sulfur concentrate of S 38.77% was also obtaine... |
