Experimental Research Of Strengthen Silver Reclaim In Galenit And Sphealerite

Silver is a vital nobel metal and It possess important status in the development of national economy. Most of Chinese silver mineral distribute in non-ferrous metal mineral,especilly in lead and zinc mineral. At present 85 percent silver of Chinese is produced from non-ferrous metal mineral. How to raise silver reclaim rate of non-ferrous mineral is a concernful problem, which not only contact with how to use ore resourse but also contact with how to develop production of silver and raise corporation benefit.At first for asscertainning technic route and experimentation project , the production of FengNing siver mine lead snd zinc mineral rock appraisal and mineral technilogy is analyzed in science.It's displayed 98% silver mineral of FengNing silver mine distributes in galenite and sphalerite and associate with galenite and sphalerite close., 1% silver mineral distributes in gangue. Galenite and sphalerite is main carrier mineral and silver mineral is too small to reclaim solely. Only try our best to raise reclaim rate of lead mineral and zinc mineral then we can strengthen reclaim of silver mineral.Then in this disquisition by experiment of selectivity of pure Galenite and sphalerite, the rule is asscertained that the mine slurry pH and different adjust medicament and catch medicament and restrain medicament kinds and dosage affect flotation .At the same time action mechanism is discussed deeply.On the base of theorial study,ore experiment is made and feasible grind granularity and medicament system and the flow of Galenite flotation firstly is ascertained.
