Refining – THE DANCOR PROCESS™

"The epitome of superior technology and design is not when anything else can be added, but rather, when nothing else can be taken away.”
Dancor Spies (Innovation Hub CSIR South Africa, Feb 2008)

The merits and intrinsic worth of THE DANCOR PROCESS™ have weathered the intense scrutiny of Gold Fields, Rand Refinery, as well as Metal Process Laboratories. All aspects including the composition of the effluent stream have been analyzed, verified, and confirmed.

Not only is THE DANCOR PROCESS™ the most cost effective and commercial viable option, but is, taking into account all attained results, a paradigm shift from the conventional.

  • Cost effective – Less than US$ 5.00 per kilogram refining cost excluding CAPEX.
  • Increased yield – additional ore to final product efficiency saving up to 25% when the use of mercury is discarded.
  • NO production or “in process” loss whilst being operated within a “closed” hands free arrangement with the physical handling of gold reduced to the absolute minimum.
  • NO dormant or latent plant inventory. What goes in comes out.
  • Bulk efficient – Modular Plant capacity from 10 kg to 1000 kgper shift/ day.
  • Completely and totally environmentally friendly;
    • NO hazardous or toxic waste,
    • NO toxic fumes, gas or greenhouse gasses emitted,
    • NO water, air, noise or environment pollution,
    • NO cyanides,
    • NO mercury,
    • NO solvents,
    • NO chlorine gas and,
    • NO metallic chemicals used.
  • Extremely tolerant process with consistent output quality.
  • Reduced production time cycle.
  • Reduced plant inventory.
  • A wide variety of feed metals from as little gold content as 100.0 (10%) fineness can be accommodated. Perfectly suited as a method to refine gold to a purity of 99.99% (999.9) fine and higher:
    • Cathode Sludge (Wet or dry);
    • Granular or Atomized Bullion;
    • Zinc precipitation filtrates;
    • Doré Bullion;
    • Alluvial Tailings;
    • Recycled jewellers waste.
  • Process and results verified by;
    • Rand Refinery Ltd, South Africa (The leading gold refinery in the world).
    • Gold Fields Ltd, South Africa (The fourth biggest gold mining company in the world).
    • Metal Process Laboratories (Pty) Ltd, South Africa (The leading independent provider of analytical services in Africa).
