Flowsheets used in the flotation of porphyry copper ores are relatively simple compared with the flowsheets used in the flotation of massive sulfide ores. The most typical flowsheet is shown in Figure 12.10. There is some deviation in the flowsheet shown in Figure 12–11, used by El Salvador (Chile), which utilizes cascade flotation of the

Sulphide Gold Ore Treatment by Leaching and Flotation Process

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.
