Abstract — Sulfidic mine wastes are problematic since they contain reactive minerals rich in heavy metals, such as pyrite. These wastes can lead to serious environmental problems and high tailings management costs if not appropriately managed. There is a need for long-term approaches for transforming these wastes to move toward zero environmental footprint, such as ‘how can they create new economic value, minimize its environmental impacts and diminish liability from mining waste?’. One practical solution is to employ paste backfill technology which allows operators to store, backfill or recycle wastes as secondary resource, innovative and environmentally sound system. Paste backfilling technology for underground mine backfill and surface tailings disposal applications has recently gained a great popularity mainly due to increased tailings usages, reduced rehabilitation costs and environmental impacts, and enhanced ore extraction and security conditions. This paper aims at introducing the concepts of underground paste backfill and surface paste disposal for sustainable mining and backfilling operations.
