After leaching of the malachite ore, copper passing into the leach solution was recovered in the form of metal by the cementation reaction with metallic zinc. The metallic copper produced by the cementation process cannot be obtained at high-purity due to the impurities in the leaching
A method of leaching copper from a heap of ore which method includes at least one resting step followed by an irrigation step, wherein, during the irrigation step a leach solution that contains chloride ions is applied to the ore at a higher rate than during the resting step.
for zinc manufacturing, the ore is leached with sulfuric acid to extract the leadzinc. These pro-cesses can operate at atmospheric pressure or as pressure leach circuits. Leadzinc is recovered from solution by electrowinning, a process simi-lar to electrolytic refining. The process most com-monly used for low-grade deposits is heap leaching.
