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.
Unexpected piezometer trends in a tailings dam triggered an investigation that uncovered an overlooked variable in dissipation testing – the type of saturation fluid.
It’s not every day you hear about two massive shafts being sunk side by side in Australian coal country, each with its own design, equipment, and risks.
