Abstract:
A thickened tailings storage solution was implemented at Hillendale Mine to manage ultra-fine clay tailings over a relatively short mine life project, in an environmentally sensitive setting. Constant performance monitoring and adapting to achieve the final mine plan requirement was key to the success of fine tailings management. The closure plan for the tailings storage facility (TSF) allows for natural drainage of rainwater and sustainable agriculture. The up to 18 m thick fines deposit is currently being capped with a layer of sand. This allows unhindered access for agriculture, with sugar cane planting progressing. The paper highlights lessons learned and successes achieved over the project duration.
