Introduction. The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.
A number ranging between 0.05 and 0.1m3/h/m2 of cathode surface area available for plating. It influences the surface quality of the cathode by breaking down the diffusion layer, of the rate of copper production, where a stoichiometric balance exists of 1.98 g of acid produced for every gram of copper plated.

The Mining Process. 1. Mining – Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
The process was designed to take about 16 hours to complete 30 elutions per month. The ZADRA process is characterised by simplicity of system design and operation, with low desorption rates.
