  • Gold extraction

    A refractory ore generally contains sulfide minerals, , 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 present in gold ore may adsorb dissolved gold-cyanide complexes in much the same way as activated carbon

  • Mining

    Mining is the extraction of valuable or other geological materials from the Earth, usually from an body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner.
