How to extract gold from circuit boards?
If you have turned on electronic devices such as radios, televisions, or even old phones, you should have seen the structures inside. Have you noticed those shiny golden parts on the circuit board? Those shiny things are actually gold. Due to its excellent conductivity and the ability to withstand long-term exposure without corrosion or rusting, gold is commonly used on circuit boards. Used circuit boards are not “waste”, 90% of them can be recycled and even have high value. It is similar to calling them “treasures”. It is understood that in these circuit boards, in addition to containing 30% inert oxides and 30% plastic, there are also 40% metallic substances, and among these metallic substances, there is 0.1% gold content. And how to extract the gold from these discarded circuit boards specifically? Circuit board gold extraction equipment At present, most people who extract gold from circuit boards choose “circuit board recycling equipment”, which is a very simple and convenient metal separation device that can easily separate metal substances from non-metal substances in circuit boards, and then extract gold through a series of steps. Let’s take a detailed look at the process below. Firstly, we need to distinguish between waste circuit boards, which are generally divided into two...
