form (Adams, 2016). However, the rapid depletion of amenable gold ores has alert researchers to come up with effective techniques in extracting gold from the refractory/ complex ores. Complex ores are defined as the ores that are difficult to treat by using the conventional metallurgical unit operations largely due to their complex mineralogy.
Gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. It is not uncommon for prospectors, especially those who operate metal detectors, to find a rich gold bearing specimens of ore. Sometimes the best use of ...

Sulfide ores, and pyrites in particular, have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic ...
Jul 22, 2017· Gold recovery was proportional to arsenic extraction during the oxidative leach, with >90 pct Au extraction for arsenic extraction ≥ 89 pct. Silver extraction did not follow this trend and ranged from 47 to 62 pct. Cyanide consumption was 2.6 kg NaCN per metric ton of leach residue and 5.7 kg NaCN per metric ton for the untreated ore.
What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
Oct 15, 2016· As for dissolving the gold that is not what I want, I want to dissolve the pyrite to get the free gold out. The idea of cooking it for a while sounds interesting but I don't think 400 degrees would be adequate, but its worth a try because it's not a large enough quantities to spend a great deal of money on, maybe a penny weight of gold.

Jan 10, 2020· When the ore contains a small amount of sulfide and is mainly present in the form of pyrite, the particle size of the gold is coarse. We can use a simple gold extraction process for this type of ore. When the ore contains more sulfides, and the pyrite and gold ore are co-exist, pyrite can be extracted as a by-product.
