The ore containing both the primary metal and silver is processed through either flotation, gravity separation, or magnetic isolation, depending on the minerals involved. Smelting is then deployed, utilising high temperatures to further separate the silver from impurities before a final stage of chemical processes or electrolysis.

Mercury forms an amalgam with gold, and gold was recovered by separating it from mercury by retorting. This process is no longer in wider use and has been replaced by cyanide process. The basis of cyanide process is the solubility of gold in sodium or potassium cyanide and the ability to recover gold from low-grade ore economically.
