Skorpion Leaching Process

EVALUATION OF PROCESSING OPTIONS FOR THE TREATMENT OF

The standard process for zinc sulphide concentrate treatment is the Roast-Leach-Electrowinning (RLE) process. This process is highly efficient in converting the zinc to special high grade zinc metal by roasting to zinc oxide, acid leaching and purification and electrolysis to zinc metal. The economics of this process
