Gold Refining Koras IQ

A revolutionary, patented electrolytic process which will influence the technological development in its field.



Gold alloys with a gold content of at least 55% are refined in a single step to fine gold with a purity level of 99.99%.No use of aqua regia, nitric acid or cyanide. The process is fully automated and is controlled by a microprocessor.

During the processing there are no NOx gases. The processing time required to recover fine gold with a purity level of 99.99% is not more than 8 - 14 hours. The electrolyte used can be re-used up to 80 times. There is no requirement for gold to be in the electrolyte (as was the case with previous electrolyte processes) and therefore the running costs are very low.
