Hard rock mine tailings (e.g., copper and gold mine tailings in this study) typically classify as low plasticity silt and contain 33% to 100% fine-grained particles,which are similar characteristics to materials typically used in WBCs. Covers simulated with coal and oil sand tailings had low percolation rates due to higher clay contents (clay

Recycling of Historical Mining Waste, a new New

Tailings of the Kilembe copper mine, Uganda, containing 80% pyrite, resulted in important acid mine drainage. To cope with this, tailings were fed to a tank bioleaching process, resulting in a full conversion of sulphides, hereby removing the source of acid mine drainage. At the same time, 1.38% of Co was recovered from the materials.

A critical review on environmental implications,

2019-11-15  Mine tailings, generated from the extraction, processing, and utilization of mineral resources, have resulted in serious acid mine drainage (AMD) pollution. Recently, scholars are paying more attention to two alternative strategies for resource recovery and ecological reclamation of mine tailings that help to improve the current tailing management, and meanwhile reduce the negative

How Is Mining Waste Recycled? Ecocycle Australia

Recycling The Smaller Stuff. Tailings are the finely ground rock left over after mineral processing and they are mostly stored as a watery mix in tailing dams. Despite big improvements in the construction of tailings dams, they can fail, often with disastrous consequences. Some mines reduce this risk by ‘thickening’ the tailings.
