Laboratory of precious metals

The laboratory of precious metals, represents an external section of the hydrometallurgy laboratory. It is used for the extraction and purification of precious metals (gold and silver) from:

  • Mineral complexes low grade, as is and bio-treated
  •  Scraps and wastes coming from industrial activity, (crafts jewelry, electrical and electronic equipment, mining, etc.)
  •  Tailings of chemical and physical treatments
    Conventional hydrometallurgical (cyanidation) and/or innovative processes, of low-cost and at low environmental impact, such as the thiosulphate process, are applied
