Electronic waste contains gold for about 7% of the total amount of gold in the world, computer,air conditioning,television, mobile phones and other electronic waste circuit boards all contain precious metals. As we know that gold is main component of the printed circuit board, every year e waste need more than 300 tons of gold，we can pick many gold and copper elements for refining gold. According to in-formations, the content of gold, silver, platinum and palladium in electronic waste is higher than that of raw ore. It has more benefit such as single composition and easy to handle and low recycling price.Mobile phones, for example, the amount of gold can be extracted from each phone which is 50 times the “gold content” of gold ore. One ton of PCB board can separate copper 130 kg, tin 20 kg, gold 0.45 kg and other metals.Therefore, the cost from recycling discarded electronic products and through the regeneration way to get precious metals is much less than directly getting from ore, raw materials through smelting and processing. People will pay more attention about the e waste recycling. From the point of circular economy, these discarded electronic waste still has the very high value.
Precious metal recovery refining machine is used to separate and refine precious metal from electronic waste containing precious metal chip components and anode slime, the purity of precious metal can reach 99.99%. The raw materials are mainly from waste mobile phone circuit boards, computer CPU, motherboard, VCD, CD, TV, game machine, fax machine, telephone apparatus, mobile communication and other household appliances. Industrial waste from electroplating factory, electronic components factory, printing factory, photographic materials factory, electronics factory.
