1. A new $42 million tailings paste plant commissioned in mid-2011, which has had a significant positive impact on the tailings stream. The plant process removes significant portions of the coarser content of the tailings mixture; cement is then added to these coarser solids and the mixture is used to fill the voids in the

Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, …

In addition to the metals recovery from the tailings, also the mineral fraction in the tailings can be valuable. With reprocessing, the mine tailings can be modified to be utilized in high-value products. E.g. the recent article by Wong-Pinto et al. (2021) reports biosynthesis of copper nanoparticles from copper tailings. In addition, the ...

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 …

Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water. Thickened tailings can be mixed with cement and used in construction or as backfill in underground mines.

tailings facilities and their consequence of failure. While not exhaustive, it illustrates the enormous volume of tailings that need to be safely managed. In 2001 Davies reviewed tailings facility failures up to that time and observed that all were predictable in hindsight and could have been prevented during the design and/or operational phase.
