Abstract
Based on the characteristics of a polymetallic sulfide ore from Mengzi,a flowsheet with an arsenic-sulfur bulk floatation and an arsenic-sulfur separation was chosen,where an effective and less toxic reagent,sodium propyl xanthate,was used as the arsenic depressant,and eventually,a sulfur concentrate with a sulfur grade of 43.05%,an arsenic content of 0.51% and a sulfur recovery of 79.53% can be reclaimed.
