Processes
The making of every ingot
Roast–Leach–Electrowinning (RLE)
A hydrometallurgical process that transforms zinc concentrate into ultra-pure zinc through oxidation, leaching, and electrolysis.
Oxidises zinc concentrate; gases sent to acid plant.
Calcine is dissolved to form a zinc sulphate solution.
Removes impurities via cold and hot purification.
Yields high-purity zinc cathodes from zinc solution.
Molten zinc is cast into solid ingots.
