摘要： Mining provides our society with many of minerals, metals, and gemstones for a wide variety of applications from mundane items through to expensive jewelry. But the mining operations generate waste and large empty shafts and stopes within the ground. It would beneficial to provide a lightweight material for backfill which can provide safer working conditions for miners as well as advantages in respect of weight reduction, reducing water consumption, rheology improvement and cost minimization. Equally, it would be beneficial for the lightweight backfill material to include mining tailings to reduce the impact external to the mine. However, the inclusion of mine tailings into a foam is counter-intuitive as mine tailings are generally characterized by a high proportion of small particles with sharp edges. However, embodiments of the invention provide just such a foam based mine backfill material.
