How to Recover Free Gold in a 10TPD Container Gold Leaching Plant?
If you are planning to set up a 10 tons per day (10TPD) containerized gold leaching plant, a common question is: how to efficiently recover free gold from raw ore before leaching? This is especially important when your ore contains coarse free gold particles that may not dissolve easily in the leaching process.
Case Study: Burkina Faso Client’s Question
Recently, a customer from Burkina Faso showed great interest in our 10TPD container gold CIP plant. He appreciated its easy installation and operation. However, he was concerned about maximizing gold recovery, especially for free gold particles present in his high-grade raw ore.
Why Recover Free Gold First?
Free gold refers to gold particles that are not bound to other minerals and can be physically separated before chemical leaching. If not recovered, large gold particles may fail to dissolve in the leaching process, resulting in gold loss.
Recommended Solution: Mercury Plate
In our plant design, we install a mercury plate at the output of the ball mill, supported by a steel frame (see the picture below). The ore pulp passes over the mercury plate, allowing free gold to be captured before entering the leaching tanks. This simple step can significantly increase the overall gold recovery rate.
Alternative Methods: Centrifugal Concentrator and Shaking Table
Other methods to recover free gold include using a centrifugal concentrator or a shaking table. However, installing these machines can make the system more complex and less user-friendly, especially for small-scale or pilot operations. For our 10TPD container leaching plant, simplicity and quick start-up are key advantages, so the mercury plate remains the most practical solution.
Conclusion
Our 10TPD container gold leaching plant is ideal as a pilot plant, helping you understand your raw ore and optimize gold recovery. By recovering free gold first—using a mercury plate—you can maximize your returns and ensure easy operation.
