  • Epithermal Gold for Explorationists AIG Journal

    Gold grades tend to be higher than in quartz-sulphide gold + copper and poylmetallic gold-silver vein systems, no doubt due to the more efficient mechanism of metal deposition provided by mixing the ore fluid with bicarbonate waters (Corbett and Leach, 1998). Localised high to bonanza gold grades within carbonate-base metal gold deposits are attributed to a number of factors including:

    Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, 2010. 17.10 Flotation of Arsenical Gold Ores. There are two major groups of arsenical gold ores of economical value. These are the massive base metal sulphides with arsenical gold (i.e. the lead–zinc Olympias deposit, Greece) and arsenical gold ores without the presence of base metals.

  • Photos of gold ores, quartz, telluride gold ore and gold

    Common gangue minerals in gold ores include quartz, fluorite, calcite and pyrite, but this specimen of oxidized ore also contains a considerable amount of gold in addition to the silver. It shows few sulfide minerals because it is well oxidized. Gold does not commonly combine with other elements, but there are exceptions. These are the telluride minerals such as Calaverite. This very rich

    Gold occurred in quartz–sulphide reefs within Umberatana Group quartzite and schist over a distance of ~3 km. Sulphide minerals included pyrite, arsenopyrite, galena and chalcopyrite. The major mines were Bird-in-Hand, New Era and Eureka. The goldfield was found by the discovery of alluvial gold which continued to be a minor producer in the area.

  • Epithermal Gold Deposits Geology for Investors

    17/10/2019· Epithermal gold deposits are among the richest gold deposits in the world with some bonanza grade ore shoots containing more than 1000 g/t gold, or in other words, a kilogram of gold for every tonne of rock mined. Unfortunately, the tonnage of ore in epithermal veins is typically small compared with other types of lower grade gold deposits. Gold mineralisation within epithermal veins

  • Rcovery of gold in pyritic ores Mine Engineer.Com

    Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently

  • Low-Sulfide Quartz Gold Model

    Ore Shoots Control and Distribution of Gold Mineralization Kerrich and Feng (1992) make the point that quartz and quartz-carbonate veins are common in metamorphic belts. The majority of these veins are from a centimeter to a meter thick and are formed locally. In contrast, the giant quartz vein systems, tens of kilometers in length and up to 3 kilometers in depth, are hosted in brittle-ductile
