As already indicated, gold and diamonds are the most important minerals mined on a small scale in Ghana, although industrial minerals are mined by a small contingent of the population. In the case of gold, operators are awarded licences by the government to mine in a designated area not exceeding 25 acres for three to five years.
Artisanal Gold Mining Description. Artisanal and small scale mining refers to mining activities that use rudimentary methods to extract and process minerals and metals on a small scale. Artisanal miners also frequently use toxic materials in their attempts to recover metals and gems.

Small scale gold mining is usually devoted to secondary deposits as the gold, concentrated by gravity processes, is free and easy to extract. But also small scale mining practices in primary deposits can be found in the countries under study. For this technography, the following phases and aspects were identified and querried:
iGoli is a simple, safe, and highly effective method of gold extraction that produces an extremely pure product. It consists of leaching the gold concentrate with dilute hydrochloric acid and bleach. After the solids are filtered, the gold is precipitated out with sodium metabisulphate.
One of the most serious problems confronting the mining industry today is how to profitably begin the small scale milling of ores from mines where insufficient ore has been developed to warrant an expensive mill installation, but where a large plant might be needed later.
