Refining Using Aqua Regia Process

  • Best suited for gold with an initial purity of at least 600/1000. Initial purities below this value can reduce the production capacity as well as increase process times.
  • Recommended maximum silver content: 10-12%. The percentages above these values can reduce production capacity as well as increase process times.
  • The gold should be either melted into fine grains – using a melting furnace and a grain tank – or very thin strips.
  • Strips are ideal due to their large surface area and complete dissolution when emerged in the aqua regia solution.
  • Grains, due to their irregular shape and size, are more difficult to dissolve and often leave leftovers in the reactor. On the other hand, they are quicker to produce than strips.
