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.
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.
The feed sources supplying the BTRP include the Harper South and Harper North complexes, contributing approximately 70,000t per month to the BTRP. Furthermore, the Vantage TSF and screened low-grade stockpile material add an additional 20,000t per month.
Mining of the Harper North, Harper South and Vantage dams progressed in accordance with the plan. It is envisaged that the Royal Sheba project will form part of the BTRP feed sources when this project is commissioned, and enabled through the construction of a run-ofmine (RoM) crusher circuit. This will allow the BTRP plant to treat approximately 35,000tpm of RoM material from the Royal Sheba project, thereby extending the life of the operation and ensuring its sustained output in future.
