Gold water recovery_ Price of gold plating wastewater recycling_ Precious metal recycling and refining manufacturers

Gold water recycling refers to the recycling and reuse of industrial wastewater or filtered water from gold-plating tanks to prevent water containing metal ions from entering the living environment. Gold water recycling can effectively save resources, reduce pollution, reduce costs, and achieve sustainable economic development. Dingfeng Precious Metal Recycling briefly explains the process of extracting gold water: the first step is to filter the recovered gold water. The second step is to add citric acid to the filtered golden water until it reaches a pH of 5. Place the zinc wire into the golden water, add boiling water until it completely covers the zinc wire, let it stand, and pour out the replaced water. The third step is to introduce the electrolyte into the replaced zinc wire, stir it with a Glass rod until it is muddy, and pour the muddy zinc wire into the washbasin (sedimentation is fast); Rinse the muddy zinc wire inside the beaker with electrolyte; Pour out the electrolyte after sedimentation; Pour the muddy zinc wire into a beaker. The fourth step is to add nitric acid to the mud like zinc wire, stir to remove impurities in the gold mud, and then pour out nitric acid; Rinse the gold mud with clean water four times; Pour the gold mud into the electrolyte to remove impurities, and then pour out the electrolyte; Rinse the gold mud with clean water 4 times, and do not pour clean water in the last pass until it has not passed through the gold mud; Pour the water with freshly washed gold mud into a clean bag, hold the gold mud with your hands, and pour out the water. Step 5: Take out the gold mud and put it into a crucible; Sprinkle a layer of borax on the surface of the gold mud; Use a flame gun to burn gold until it forms golden water; Cool it into golden beans.
