The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained .
ore formation is a common and intrinsic part of crustal evolution, large and super large ore deposits require the coincidence of particularly favourable combinations of processes and source parameters. This brief review outlines the key primary geochemical expressions of the main metalliferous ore deposit types found in Australia. To a large

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.
Leaching (Gold Dissolution) Once Vat is loaded with ore, is flooded with a leaching solution of a desired cyanide concentration (usually 600 to 1000 ppm) and pH between 10 to 11 at ambient operating conditions through the filter section of the floor or added to the top of the ore charge. Picture 3: Left is the loading of tails read for leaching process, while right hand side is the .
Doré bars are unrefined gold bullion bars containing anywhere from 60 to 95 percent gold. We finally send the bars to a refinery for further processing into pure gold. Alternative Ore Processing. We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements.

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
