Gold is attacked by and dissolves in alkaline solutions of potassium or sodium cyanide to form the salt gold cyanide—a technique that has been used in extracting metallic gold from ores in the cyanide process. Gold cyanide is the electrolyte used in of gold.
Ba Te Pb Co and Mo concentrations can also be used to distinguish between unaltered and altered pyrite and arsenopyrite. In general trace elements within pyrite and arsenopy-rite have a relatively uniform distribution whereas later-stage alteration ...

The Central Aldan ore district is characterized by the wide development of gold copper–molybdenum uranium plati- num and fluorite mineralization associated with the Mesozoic alkaline magmatism of the Aldan complex Fig. 1 .
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well as how to extract and process the ore efficiently safely and responsibly.
