Guides For High-sulfide Gold Processing cnlitereagent
2020-3-17 High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for high-sulfide gold ores.

Gold Recovery And How To Choose The Right Process
Sulfide-associated gold is often very fine in nature and difficult to separate from the sulfides. So how is this done in an economical and effective way? In many cases, portions of sulfide-associated gold can be considered free-milling and can be recovered using the gravity recovery process described above.

Process to Recover Gold from Sulfide Ores GOLD
2016-5-27 I'm hoping our HEPP process can either eliminate or significantly reduce the roasting step (12-18 hours at 600-700 degrees C), which is currently required for the recovery of precious metals from sulfide laden ores. If so, our process consumes a fraction (4 cents per ton) of the energy of roasting. Quote.
