Increased Recovery in Gold Leaching

Pionera biopolymers show gold recovery increase in CIL and CIP processing plants.

In laboratory bottle roll tests and plant trials, the addition of Pionera biopolymers showed a significant increase in gold and silver recoveries. Some examples are shown in the figure below.

Additional data from a 2-month plant trial can be found in the Case study Antam Pongkor.

The recovery gains are related to product dosage, and a benefit calculation can define the best dosage to be applied. A calculation example is given in Pionera L-625 for Gold CIP throughput increase.
