  • Dealing With Cyanide-soluble Copper In The Gold Mining

    A significant portion of the known gold reserves in the world are contained in ores that also contain copper mineralization. Most copper minerals react quantitatively with cyanide, which is the lixiviant used universally in the gold industry to leach gold from its ores and concentrates. In practice, it is difficult to leach gold without simultaneaously leaching any cyanide soluble gold ore processing operation from ball mill tailings,gold ore processing operation from ball mill tailings As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
