Recover Gold from Electronic Scrap/E-waste Recycling for Gold/Recover Gold from Rams/Gold Recovery from Computer Parts

Gold recovery from electronic scrap is a very lucrative business, but you must find the right source to purchase the material. There are two key things to consider when starting this business. First, you should choose the right methods to recover all precious metals from electronic waste (e-waste). Second, you should also be skilled at purchasing the material. Being good at only one of these will not help.

When we talk about electronic scrap, it is not a single uniform material. It is a mixture of various electronic circuit boards or a variety of complete devices. According to my experience, the best approach is not to process everything. You should be selective if you want to make more money in a short time. Not every component in electronic scrap yields precious metals; only specific components contain them. For example, chips, processors, gold fingers, gold-plated connectors, certain diodes and transistors, monolithic ceramic capacitors, and relays.

If you purchase a mixed lot of electronic scrap, you should first segregate the items. Then, one by one, remove the above-mentioned precious metal-bearing components. There are buyers for almost everything obtained from e-waste, so you can sell the remaining non-valuable items to e-waste recyclers.

There are simple tests to determine the presence of various precious metals. For example, if you suspect that a component is silver-plated, you can place a drop of nitric acid on it, followed by a drop of hydrochloric acid. If silver is present (either as an alloy or plating), a curd-like formation will appear on the surface. To test for gold, place a drop of nitric acid on the metal. Gold does not react with nitric acid and remains unchanged. However, metals like copper or brass will react and dissolve. Similarly, there are methods for testing palladium and platinum.

Gold plating can be removed from components using the AP process. CPUs and processors are best treated for gold recovery using aqua regia. Gold can also be removed from pins using sulfuric cells.

In my next article, we will discuss some precious metal recovery methods in detail.
