Abstract: Focus on some shortcomings exist in the electrorefining of gold, the paper present a new hydrometallurgy in refining gold.An experimental study of refining gold is made, the experimental results show that the recovery of gold come up to 99.99%, the purity of gold come up to 99.99%.The characteristics of technology include: the technological process is simple; the operating condition of technology is easily mastered; having less pollution; the cycle of production is very short and the deposition of gold is less.
