Gold vs. Pyrite. The Difference Between Gold and Iron Pyrite
Gold and pyrite are very different minerals, but because of their similar color they are often confused by beginners gold panning for the first time. Prospectors will often find lots of little gold specks in the bottom of their gold pan, and think they have struck it rich. Pyrite is often called "Fool's Gold", but after reading this article you will understand how to avoid being a fool....

Ore deposits formed by oxidation and supergene enrichment
Ore Deposits Formed by Oxidation and Supergene Enrichment · When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. · The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. · An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or ....

Rcovery of gold in pyritic ores
Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This generally involves frother, several collectors (promoters) and possibly some modifying or depressing agents as well....
Cyanidation of gold ores containing copper, silver, lead ...
Jul 01, 2010· In such refractory gold ores, gold particles may sometimes be occluded or included in the sulfide minerals and pretreatment is necessary to decompose the mineral structure to liberate gold for subsequent recovery. These ores are usually pretreated by some oxidizing process after which gold and silver can be recovered by standard cyanidation ......

Gold Occurences | Natural Resources
Gold Occurences; Gold Occurences. compiled by R. James Weick, 1994. Gold, the noblest of metals, has been used by man for more than 5000 years. Its extreme softness or malleability, and resistance to tarnish (oxidation), led to its earliest uses in art and currency. Gold is the metal of choice for jewellery, and is often used in dentistry....
