Gold mining Wikipedia

Zinc is added to precipitate out residual zinc as well as the silver and gold metals. Other gold mining impacts, particularly in aquatic systems with residual cyanide or mercury (used in the recovery of gold from ore), can be highly toxic to people and wildlife even at relatively low concentrations. However, there are clear moves by many in the non-governmental organization community to

Recovery of Gold by Precipitation with Zinc

The recovery of the precious metals like gold and silver from the cyanide solution is almost universally accomplished by precipitation with zinc, either in the form of fine threads or of dust (the condensed fume recovered in the process of retorting the metal).. The phenomena of precipitation are essentially electrical and may be traced to the action set up by two metals of different

Recovery of Gold as By-Product from the Base-Metals

A lead–gold prefloat prior to the zinc flotation allowed the mine to recover 7100 oz of gold in 1992, in a concentrate assaying 71 g/t Au. In general, however, the gold grade and the mineralogy do not allow the separation of gold from the zinc at the mine and gold is incorporated within the zinc concentrate, or is left behind with the pyrite, as is the case at the Olympias mine in Greece

Use in Mining International Cyanide Management Code

Gold and silver typically occur at very low concentrations in ores less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous stone (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore. Typical hydrometallurgical recovery involves a leaching step during which the metal is dissolved in an
