Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

Electrowinning has proved to be an effective and simple method for recovering gold from the eluate. Electrowinning is done simultaneously with the elution. The barren eluate is recycled to the eluant tank and is recycled for the next elution after the reagents have been made up to their relevant concentrations.

This process is completed after every strip to remove the gold sludge. for that reason, EC series electrowinning cells have an incorporated anode and cathode slide system that enables the easy cleaning and sludge removal to take place within the cell. This system effectively removes most of the manual labour from the electrowinning process.

Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably).

Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution. The positive terminal from the rectifier is connected to the anode where the oxidation reactions occur and electrons are generated.

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
