A hydrocyclone with involute feeding.
A cyclone unit design with high efficiency.
The recycling of printed circuit boards from obsolete computers is, at present, a fairly new activity in Brazil, although opportunities are available for expansion in this area. For instance, gold, silver, tin, and copper, among other metals, can be recovered by means of the hydrometallurgical treatment of printed circuit boards (PCB) from
quotGold is stripped out from circuits in about 10 seconds, leaving the other metals intact,quot Foley said. Foley said it requires 5,000 litres of aqua regia to extract one kilogram of gold from printed circuit boards, none of which can be recycled.
Oct 27, 2010018332Most circuit boards contain all sort of precious metals Gold, Silver, Palladium and sometimes Platinum. All circuit boards contain base metals Copper, Nickel, Aluminum, Zinc, Tin, Lead and Iron. As well, small amount of hazardous elements like Beryllium, Barium and others that has to be considered while processing scrap circuit boards.
Dec 19, 2013018332 In this video tutorial i'm showing how to recover gold from electronic circuit board scrap. Specifically the gold plating that is f
If you want us to assist you for recovering gold through aqua regia method please write us at [email protected] Q.6 How to recover gold from CPUs ? Ans. There are many methods which can be used to recover gold from CPUs, but aqua regia is the best method for it. Use nitric process or CN process to recover gold from green fiber CPUs.
