  • Process to Recover Gold from Sulfide Ores GOLD

    I'm hoping our HEPP process can either eliminate or significantly reduce the roasting step (1218 hours at 600700 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.

  • Recovery of Gold in Pyritic Sulfide Ores mineengineer

    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% recovery.

  • Sulfides Gold Recovery Methods ICMJ's Mining Journal

    We have had great sucess recovering gold from sulfides with out thiourea based solution. Our recovery rate is usually 94 to 96%. The key to recovery with sulfides is the grind size of the ore while leaching to make sure that your leach solution can make Co tact with the precious metal.

  • How to Extract Precious Metals From Sulfides Sciencing

    Separating Metals from Sulfur. Employ bioleaching for base metals, such as zinc, copper and nickel, or mineral bioxoidation to enhance extraction of gold and silver. Both methods rely on bacterium, such as hiobacillus ferrooxidans, to recover precious metals. For example, stack ore in piles 200 feet deep.
