Unexpected piezometer trends in a tailings dam triggered an investigation that uncovered an overlooked variable in dissipation testing – the type of saturation fluid.
A new study has shown that bioleaching can strip more than 90% of sulphur and iron from coal waste, neutralising its acid-generating potential and creating a saleable by-product.
Seiche waves might be rare in mining, but new research shows they could pack enough force to overtop in-pit tailings storage facilities with serious consequences for operations, infrastructure, and safety.
A waste stream from iron ore processing is proving it can outperform conventional materials in building mine haul roads and deliver major environmental gains.
