1. How do you extract gold from electronics at home? To extract gold from electronics at home, get yourself a device that can separate the pure gold wire. The easiest way to do it is by using a centrifuge machine. It separates all types of materials via different densities and weights at high speed with a low damage rate on each material.
To recover gold in the laboratory experiment, the team salvaged the electronic motherboards from 20 old computer motherboards and extracted the metal parts. They dissolved these parts in an acid bath so as to ionize the metals. How the gold is recovered: Gold ions adhere to a sponge of protein fibrils.

a white sediment instead of the expected brown precipitate when attempting to extract gold from computer parts, there could be a few potential reasons: 1. Incomplete dissolution of gold. The acids used (like aqua regia) may not have fully dissolved and brought all the gold into solution before precipitation. Ensuring complete dissolution is key.
To understand the components containing gold, you need to know how to extract gold from old computer parts. Circuit boards, processors, and RAM sticks are the most common components that contain gold. We'll explore these components in detail to give you an idea of how to identify and extract gold from them. Circuit Boards
