Gold Refining Plant
Gold Refining Plant
This gold refining plant is able to treat from 300 gram. up to 10 kg. of starting gold alloy. You are able to produce 99.99% pure gold (Au) in a single step within a production cycle that can last from 5 to 8 hours, from the preparation of the grains, to obtaining the pure ingot. The treatment takes place by dissolving the staring metal alloy through the use of the so-called “Aqua Regia” solution, an opportunely calibrated mixture of hydrochloric acid (HCl) and nitric acid (HNO3).
- Alloy Batch Charge 1 Kg to 100 Kg.
- Working Cycle Time In – 24 Hr 3 Batches
- Purity Can Be Obtained – Form 999.5 to 999.8-9/1000
- Electric Power Supply – 3Ph & 1Ph, Working Area – 10 ft. x 10 ft.
Machine advantages
- Very compact plant
- Easy handling
- Low operation costs
- No fumes
- No gold losses
- Automatic acid loading
- Very low maintenance system
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.
