IsaMill will be implemented at Pogo’s inline leach reactor (ILR) circuit, where it will finely grind the ILR residue from 240 microns to a product of 25 microns to improve gold recovery in the downstream leaching process.
Greg Rasmussen, Glencore Technology’s process and business development manager for the Americas, said IsaMill was developed to be much more energy efficient than alternative grinding technologies – thus providing improved sustainability outcomes for mining operations around the world.
“Our technology has been successfully used commercially in concentrator plants for over two decades,” he said.
To ensure accurate scale-up, the Pogo Mine utilised the IsaMill Signature Plot procedure, supported by a certified commercial laboratory. IsaMill Signature Plot tests are globally recognised in determining the required energy parameters for fine and ultrafine grinding of ores using the technology, Glencore Technology said.
