Geometrics Knowledgebase :: Will the magnetometer find gold?

Feb 14, 2011  Placer gold is the type found in buried stream channels such as the gold which sparked the California gold-rush in 1849. Gold dust and magnetic minerals have been concentrated in river banks over thousands of years. Where there is gold there is often magnetite and therefore the magnetometer can be used to locate placer gold deposits.

Cyanide Use in Gold Mining - Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
