  • Dissolving Ore? - Gold Prospectors Association of America

    Oct 15, 2016· This is an alternate method to using AquaRegia. The problem with using acids like this with "gold ore" is that other metals are almost always present in the ore with the gold, so once you dissolve the gold into solution, other metals are also spoiling the mix, which makes removing the gold even harder to do. Sulfuric Acid will "not" dissolve gold.

  • Gold extraction - Wikipedia

    A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved gold-cyanide complexes in much the same way as activated carbon.
