Sulphide Mineral Indicators For Gold BC Gold Adventures

Mar 25, 2019 Sulphide Mineral Indicators For Gold Sulfide minerals can provide important clues for small-scale gold miners and prospectors in locating both placer and lode deposits. This is especially true when it comes to lode or vein gold. The following are some of the main sulfide mineral indicators you should keep an eye out for when prospecting.

Recovery of Gold in Pyritic Sulfide Ores Mine Engineer.Com

Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This generally involves frother, several collectors (promoters) and possibly some modifying or depressing agents as well.

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
