System and method for the recovery of metal values from slags, drosses, and other metal-bearing materials
A method of recovering metal values from metal-bearing materials such as slags and drosses includes the steps of pulverizing the material to particles less than about 100 μm; leaching the pulverized material with a solution of ammonium chloride, sodium chloride, and potassium chloride; sequentially...

Summary: | A method of recovering metal values from metal-bearing materials such as slags and drosses includes the steps of pulverizing the material to particles less than about 100 μm; leaching the pulverized material with a solution of ammonium chloride, sodium chloride, and potassium chloride; sequentially recovering at least two metals from the leachate by the addition of zinc using a sequential cementation process; and recovering zinc from the solution by electrowinning. |
