In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to distFollowing small-scale mining is mid-scale mining, which today is extremely complex. Production units that operate on this scale are identified on the basis of mining contracts. However, the actual geographical distribution of such mining contracts is unknown, and thus, no clear structures exist that can regulate their functioning.throughout the world. While the vast majority of artisanal and small-scale gold mines in Mozambique use mercury amalgamation in the gold mining process, the privately owned Clean Tech Mine in the Manica Province has eliminated the use of mercury at their mine. Instead, gold is isolated by centrifu-gation and magnetic removal of gangue materials.
