· In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straightforward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. This process is not supposed to be lucrative.

The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance. Generally, scrap with a gold content of less than percent, unless readily

The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore. Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away. The remaining substances will be just water and gold, the
