| In tbis paper,the mineral character of sllver ore is described in detail,According to mineralogy of the silver ore,a new mineral processingtechnology asynchronous bulk flotation-regrinding of rougher concentrate separation of Cu from Pb-Zn is developed.The test resuIts indicated that,the new mineral processing technology is suitable for treatment of sulphide silver ore containing poor associated Cu ,Pb and Zn,Good metallurgical resuIts were obtained,Comprehensive utilization of the silver ore was achi.eved,It is of significance to increase economical benefits of mines. |
