Designing for Optimized Tailings Storage Economics

The impacts of the economic storage or disposal of mill tailing wastes are becoming more important to the mining industry as environmental regulations become more demanding. Mill tailings have long been considered the stepchild of the extraction process and have not, until recent years, been treated as a separate entity of the mining and milling process with distinct and complex physical and chemical characteristics. As a waste product, the economic value of mill tailing is usually very small whilst economic and the environmental liabilities can significant. be Disposal of tailing is commonly identified as the single most important source of environmental impact for many mining projects.
