Practical Considerations in the Hydro Re-Mining of Gold Tailings
Tailings reclamation by hydraulic re-mining involves recycling water from the treatment complex or process plant to booster pump stations from where it is delivered at high pressure directly to the monitor guns at the reclamation sites. These guns direct high-pressure water jets at the tailings to break it up and re-create a pulp.

Tailings management - Naue
As mine sites increase in size, the engineering needed to properly contain the volume of tailings has intensifi ed. This scaling up of containment frequently requires not just lining systems but reinforcement and sealing systems for perimeter berms on tailings pond. Weaker, earthen-only berms are at risk of saturation, erosion, and failure.

Background. Recent major tailings dam failures have led to an industry-wide 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).
