Tailings ponds are one of the three major production facilities in metal mines. The volume tailings increases year by year, but storage capacity existing is limited. Therefore, dams must become more fine-grained and larger. potential hazard they represent should not be underestimated. This paper reveals causes regional distribution patterns 342 dam failures globally from 1915 to 2021 through st...

Historically, tailings facilities have been designed primarily with consideration of the mine’s active life. This is problematic, as lifespan a dam may far exceed life mine. Over time, it expected that these structures will transform into mine waste structure and then eventually landform. In Alberta, Canada, owners can submit decommissioning, closure, abandonment (DCA) plan completion reports t...

The acid-forming potential of lead/zinc (Pb/Zn) mine tailings at Lechang City of Guangdong Province was studied using both net acid generation (NAG) and acid-base accounting (ABA) methods. The pyritic and total sulfur contents of the tailings were 12.6% and 18.7%, respectively. The mean acid neutralization capacity (ANC) was 63.5 kg H2SO4/t while three oxidized tailings samples had an ANC less ...

The ceramic materials industry has vast potential for use of waste from industrial processes, such as iron mining tailings. aim this study was to test technological tailings samples the dam rupture Samarco S.A. Company in 2015 produce structural ceramics. Sedimentation and flotation processes were used improve their characteristics, analyzing chemical mineralogical composition granulometry. We ...

The failure of a tailing dam occurs due to damage to the particles’ micro-structure. Understanding the deformation characteristics of the particle’ micro-structure is important for understanding the mechanics of instability in tailing dams. In our study, a series of experiments was conducted using a testing apparatus for micro-mechanics and the deformation of tailings from the Huangcaoping tail...

Tailings dam disasters are reported almost every year and triggered by mechanisms, such as overtopping, piping, others. The failures due to inadequate management cannot be neglected well. These dams constructed mostly in a step-by-step construction method that leads continuously changing state of vertical loads during may lead particle breakage changes strength. Therefore, layer tailings today ...

This study compares coal mine tailings management strategies using life cycle assessment (LCA) and land-use area metrics methods. Hybrid methods (the Australian indicator set and the ReCiPe method) were used to assess the environmental impacts of tailings management strategies. Several strategies were considered: belt filter press (OPT 1), tailings paste (OPT 2), thickened tailings (OPT 3), and...
