  • Sulphide Gold Ore Treatment by Leaching and Flotation

    Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

  • Guides For High-sulfide Gold Processing

    High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

  • A review of major non-sulfide zinc deposits in Iran

    01/01/2018· The association of carbonate-hosted non-sulfide zones with underlying massive sulfides in combination with the characteristics of the non-sulfide ore suggests that most of the known non-sulfide mineralized zones in Iran are the result of supergene, direct replacement process of CH and SEDEX deposits. Zinc and Pb non-sulfides can also be used as indirect indicator minerals for exploration of

  • Gold extraction Wikipedia

    Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved gold-cyanide complexes in much the same way as activated carbon. This so-called "preg-robbing" carbon is washed away because it is significantly finer than the carbon recovery screens typically

    04/09/2015· It all depends on your sulfide product what you have to leach. Leaching works poorly on coarser gold it just takes forever to dissolve. Some types of sulfides react badly with leach systems, destroying the leach chemicals. If you have significant silver in your ore, many non-cyanide leach systems dont recover silver. It will be left behind

  • The Mining Process Newmont Corporation About Us

    Refractory ore resists normal processing methods as the high sulfide minerals trap gold particles, making it difficult for the cyanide to reach the gold and leach it. Heating. To leach gold from refractory ore, it must be subjected to high temperature, high pressure and/or oxygen. Newmont treats refractory ore in two ways: by using an autoclave or a roaster. An autoclave is used before

    Abstract: Naturally, refractory gold is enclosed by sulfide minerals such as pyrite and arsenopyrite and a higher content of organic carbon, which results in difficulty in the recovery of gold. In this study, the flotation gold concentrate before and after pressure oxidation (POX) was analyzed. The analysis of the Eh-pH diagram revealed that pyrite/arsenopyrite would be dissolved in higher
