ORANO undertook a tailings deposition review for the JEB Pit Tailings Management Facility (TMF) at the McClean Lake uranium mill in northern Saskatchewan.  After initial screening, two tailings deposition alternatives were advanced to the detailed review stage.  The first option included Read more... about The Investigation of an Alternative Tailings Deposition System for Uranium Tailings

Tailings management at the Hope Bay Project in Nunavut, Canada, includes reliance on an innovative frozen core dam. This dam does not have a tailings beach against it, and has been designed as a water retaining dam with a 30-year design life. The dam foundation is subject to significant long- Read more... about Frozen Core Tailings Dam: Part 2, Long-Term Creep Deformation

Filter pressing is a viable and proven tailings management alternative. Building on the experience at successful dry-stack operations, operating at production rates of up to 30,000 tonnes per day, filter-pressed dry-stacking can be (and is being) considered as an economically feasible tailings Read more... about Filter-Pressed Dry Stacking: Design Considerations Based on Practical Experience

The reclamation of tailings deposits is dependent upon long-term consolidation, which determines both the final storage volume and ultimate deposit strength. Very soft materials like flocculated mature fine tailings undergo large deformations during consolidation. Describing this “large strain Read more... about Assessing Oil Sands Tailings Consolidation Parameters Relative to Long-term Reclamation

SRK Consulting's Cape Town office, together with its Vancouver office, has conducted preliminary groundwater modelling to assist a South American mining client in finding an environmentally sustainable solution for tailings-based brine management. Read more... about A Model Solution

Large volumes of wastes are produced by the mining activities and mine waste management is one of the most important environmental issues which directly affect the feasibility of the mine related to permitting. The slurries or waste materials left over after mineral is extracted from ore via Read more... about Evaluation of Turkish Mine Waste Management Policy with Respect to Marine Pollution
