Electronic waste can extract gold, is that true?
Electronic waste can extract gold, is that true? For the answer to this question is yes, mainly in two ways:
One kind is burned purification method, this method is the oldest, the purification efficiency is not big, mainly in some outdoor venues will be used, but this method to the environment pollution is bigger, in the combustion process produces a large amount of waste gas, and complete combustion of waste electronic products will produce large amounts of organic matter in addition to precious metals scum, excessive amounts of precious metals such as lead to the human body harmful gas will escape into the air to the secondary pollution in the air.
Another way to high temperature liquid purification method, mainly is to use solution with silicon and separation of precious metals from the circuit board, in this way can better extraction circuit boards of gold, silver, copper and other precious metal elements.
For high temperature liquid purification method, many manufacturers using strong acid for separation of precious metals, this method also has many disadvantages, through our company’s research, through our gold striping equipment to get gold on the surface of the electronic waste, through precious metals recycling machine the gold、silver、platinum 、palladium from the electronic waste，no pollution, no harm, is the best way of precious metals recycling.
