Minerals | Free Full-Text | Particle-Crushing ...

In solid backfilling coal mining (SBCM), the crushed gangue backfilling material (CGBM) is generally compacted circularly by a compaction machine in order to reduce its compressibility. In this cyclic compaction process, the particles are crushed, which has a significant effect on the deformation resistance of CGBM. However, the deformation resistance of CGBM is critical for controlling ...

The environmental impact of gold production

2019-7-25 · The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore). Electricity use was responsible for just over half of the GHG emissions. This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages.
