Optimization of the operating parameters in gold electro-refining
As a result, in the absence of platinum group metals, the purity of gold reaches 99.5 %. At the next step, gold begins to react with chlorine to form gaseous chlorides. To prevent gold loss, most of the refineries stop the process at 99.5 % gold grade and continue the refining by electrolytic refining (Mooiman and Simpson, 2016).
