Increasing Gold Recovery in a Falcon Concentrator With Biopolymer Addition

Pionera L-800 improved gold recovery significantly in a gravity concentrator.

Data from a field study at Antam Pongkor mine shows increased gold and silver recovery in a falcon concentrator.

The CIL gold plant of Antam operates a gravity circuit fed from the ball mill discharge. Pionera L-800 was dosed at 400 gpt to the ball mill during a 3-month plant trial.

Key takeaways

  • Gold recovery in the falcon increased by 5% over an increased gold feed grade.
  • Medium particle sizes in the falcon feed decreased by over 10%.
  • Slurry viscosity in the feed ore also decreased, causing fewer screen blockages.
