The golden reduced solution was selected as the raw material. Using extraction and optimization of palladium refining process to extract gold from gold liquid after a reduction and palladium products. The acidity, temperature, reduction time to the influence of gold extraction process were investigated. The experimental results showed that, the new technology of extracting gold, palladium has the following advantages: the product with high yield, stable quality, the operation was simple and the production cost was low, the new technology with high industrial application and popularization value.
