Refining
A series of chemical processes are required to separate precious metals from lower-value metals in scrap gold and refine them to a purity of 995.0 or 999.9. At ISGOLD Gold Refinery, we use the aqua regia method to recover nearly 100% pure gold of the best quality, returning it to nature. The aqua regia method is widely preferred by many refinery organizations worldwide, and our highly skilled engineers ensure that we minimize environmental pollution, in line with our environmental policies, while adhering to the highest standards.
