Gold is mined in the form of microscopic particles in concentrations as little as 0.5 parts per million (ppm). As a result, simple tools have been replaced by complex equipment and chemical processes to extract gold. Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows:
