| Abstract: |
| A mixed nitric-sulphuric acids is used to recover the valuable metals Ni,Cu and Co from low-grade Ni-Cu sulfide tailings,the leaching rate of Ni,Cu,and Co is 91.5%,85.0% and 54.6% respectively under laboratory conditions. This leaching procedure is operationally simple and economical,which may be applicable in an industry scale for the recovery of valuable metals from Ni-Cu sulfide tailings. |
