grinding zinc ore

Lead and Zinc Ore beneficiation Due to low zinc content, runofmine zincbearing ores must be concentrated before smelting and refining Beneficiation, which usually occurs at the mine, consists of crushing, grinding, and flotation to produce concentrates of 50 to 60 percent zinc...

WO2010108212A1

A method for leaching zinc from a zinc-bearing carbonate ore, the method comprising the steps of: subjecting the zinc-bearing carbonate ore to elevated temperatures of between about 300°C and about 900°C thereby producing a roasted ore; subjecting the roasted ore to an aqueous acid or alkali leach thereby producing an aqueous zinc solution; and subjecting the aqueous zinc solution to a zinc ....

Zinc Pressure Leaching (ZPL)

Zinc pressure leaching (ZPL) treats zinc concentrate directly in the autoclave where specific temperature and oxygen partial pressure is given to leach zinc and generates zinc sulfate solution while sulfur, lead and iron remain in the residue (leaching residue)...
