Mining environmental management primarily focuses on concerns over the impact of waste disposal on the surface, in the form of tailings and waste rock. Traditionally waste products have only been returned to the mining void in limited quantities and surface disposal technologies have been paramount. Mining systems need to be reengineered, based on a new paradigm that mining is a business whose success is fundamentally dependent upon waste management. Strategies are available to shift this paradigm and to minimize the surface impact of waste disposal. Firstly, mining methods need to be developed that are more selective. A more futuristic strategy may be the implementation of solution mining. Pre-concentration and even the full integration of mineral processing within the mine workings could be important in this strategy in the interim. Secondly, technologies enabling the return of waste securely to the void should be pursued. This paper considers the design of new mining methods that minimize waste output. It then reviews technologies for in situ pre-concentration. Finally it addresses the issues associated with the return of waste to mined voids. |
