| Abstract: |
| Based on the characteristics of Dachang No.100 rich,ore two principle flowsheets of magnetic separation flotation gravity separation,and magnetic separation gravity separation flotation gravity separation are selected.The flowsheet of magnetic separation flotation gravity separation has been used in industrial production.The cyanide free flotation is used for separation of lead from zinc,Commercial practice proved that the advantages of this flowsheet are simplified,less investment and short construction period.The problem of great difference in size range of cassiterite and sulphide minerals has been basically solved. Better metallurgical performances and considerable economical benefit have been obtained .The recoveries of tin,lead and zinc are respectively up to 83.60%,79.47%and 82.07%.The expanded test proved that the advantages of this technological flowsheet for separation of cassiterite slime with injection flowing centrifugation machine are non pollution,lower cost and feasible in economy. |
