Emerging Technologies in Mine Waste Management

The management of mine wastes generated by both active and inactive mining is an ever more challenging issue. The cost to manage and treat mine wastes, including tailings, waste rock, treatment sludge and slag, is estimated at over $50B in Canada and the United States alone. Cost-effective technologies are required to meet both short and long term challenges and increasing environmental standards. This paper will provide an overview of novel and conventional technologies to manage mine waste particularly in the areas of waste stabilization, treatment and disposal technologies.
