Ballarat Gold Mine – Processing Plant Expansion

Como Engineers was engaged by Victory Minerals to expand the processing capability at the Ballarat Gold Mine in Central Victoria. The expansion comprised three distinct scopes: an additional 1 MW ball mill, a 1 Mtpa CIL circuit, and a 2T Pressure Zadra elution circuit and regeneration kiln, together with tailings reclaim infrastructure.

Ball mill: An additional 1 MW ball mill was installed into the existing grinding circuit to deliver a more consistent grind size, improving recovery in the flotation circuit and enabling tailings reclaim for reprocessing, allowing the plant to operate at a higher utilisation level. Tailings reclaim infrastructure was installed to enable reprocessing.

CIL circuit: A 1 Mtpa CIL circuit and associated infrastructure were installed.

Pressure Zadra elution circuit: The scope included a 2T Pressure Zadra elution circuit and regeneration kiln.
