Project at a Glance
  • Gold is produced at some mines as part of the process of mining and refining other metals, such as copper. At those operations, gold is refined to an acceptable purity as part of the copper production process. At most gold mines, the gold "dore" is sent to a refinery for further processing
  • Under rules established by the London Bullion Market Association, LBMA, these bars — the gold standard of the gold world — must be at least 99.5 percent pure gold, weigh between 350 and 430 ounces (most weigh about 400 ounces), and be stamped with a unique serial number, the fineness, and the seal of the refiner.
  • Modern refineries use chemical or electrolytic processes to separate pure gold from other substances. In the Miller Process, chlorine gas is bubbled into the molten gold. The impurities within the gold separate from it and form chlorides, which concentrate on the surface of the molten metal. It is then relatively easy to pour off the purified gold, which is about 99.5% pure.
  • Gold of even greater purity (99.99%) is created by more complex and expensive electrochemical Wohlwill Process. In this, an electric current is passed through an electrolyte solution of hydrochloric acid and gold chloride. Gold of 99.5% purity is used as the anode and 99.99% pure gold plates out onto the cathode.
  • Refined gold is subject to 10-percent import duty in India as opposed to eight percent on gold doré, which at current prices equates to a differential of $25 per ounce – much higher than the approximate $1-2 cost of refining & hence the profitability of this Project
