Retreatment of gold residues

 · Goldmining residues typically fall into one of three egories comprising slime (particle size of about 75% passing 74 μm), sand (about 10–20% passing 74 μm) and waste rock. Since the slime and sand has been previously processed, it typically has a low gold grade (< g/t) and will provide relatively low recovery efficiencies, in the ...

Best Practices for Tailings Dam Design

 · Background. Recent major tailings dam failures have led to an industrywide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly into ponds, lakes, rivers or natural topographic depressions, or stored in impoundments supported by earthen dams, without necessarily applying engineering principles (McLeod et al. 2015).
