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.
