  • Tailings

Summary:

The BTRP section retreats previously processed gold ore in the form of slime material. The slimes emanate from historical mining activities on the same orebodies that are currently being mined underground from the existing Barberton Mines underground operations.

The material is confined to the deposition site of historical tailings and approximately 1m beneath the historical footprint. The ore consists of oxidised tailings containing pyrite and arsenopyrite associated gold, which was not recovered in the initial treatment process.

Mining Methods

  • Hydraulic mining

Summary:

Barberton Tailings Retreatment Plant (BTRP) is a surface re-mining site with road access from all surface material sources to the plant. Ore is either pumped (hydraulic re-mining and Fairview plant tailings) or trucked (load-and-haul) to the BTRP plant.

Summary:

At Barberton Tailings Retreatment Plant (BTRP) ore is milled in a regrind mill and processed through a CIL, a carbon regeneration and elution (and electro-winning) section. The BTRP also has its own smelt house. The BTRP has a capacity of approximately 100ktpm.
