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 allcyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

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 recoveryFurther Details
Sulfide Ore Processing Placer Gold Sulfide Ore Processing Home → Sulfide Ore Processing Processing Sulfide Ores Historically miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls However with the implementation of the Mercury Export Ban of 2008 and the high costsFurther Details
Sulfide minerals can provide important clues for smallscale 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 Bear in mind mineral indicatorsFurther Details
Gold In southern Africa two xray sorters are used to preconcentrate sulphide gold ore into two different grain size categories While the input material has an average gold content of less than 08 gt the sorted product achieves a concentration of more than 4 gt with an efficiency of approximately 90Further Details
Speed of extraction is another area that Conti says cannot be beaten ‘We have been testing sulphide ores and are able to do the entire process from sulphur reduction extraction and recovery to powdered gold in an hour and a half That same material would take 36 hours with cyanide which only gets an 83 extraction efficiencyFurther Details
This paper deals with the application of biotechnology to enhance gold extraction from refractory sulphide mineral ores Bioleaching tests were performed with inocula two levels old 7 and 14 daysFurther Details

Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult Treatment of the roasted ores was done by normal methods such as amalgamation or cyanide treatmentFurther Details
