Antam Pongkor mine, Indonesia – Increase gold recovery and throughput in a CIL gold process with Pionera BioPolymer.

Abstract: In an effort to reduce the impact of declining head grade, a biopolymer was evaluated as an additive in the gold leaching operation at Antam Pongkor in Indonesia. Laboratory testing revealed that biopolymer usage lead to an increased gold recovery without apparent negative impact on the other parts of the process. Further plant trials revealed both a recovery increase around 1.3% and a throughput increase by 9% in the presence of Pionera L-800.
