摘要

Mining environmental management tends to focus on concerns over the impact of waste disposal on surface, primarily in the form of tailings and waste rock structures. This relates to the fact that 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, i.e. leave waste in place. The eventual, more futuristic outcome of this strategy may well be the implementation of in situ or solution mining. The adoption of 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 should be further pursued that enable the return of waste securely to the void. This paper considers the design of new mining methods that minimize waste output. It then reviews technologies for in situ pre-concentration and mineral processing. Suitable processing technologies with a small footprint, that require limited infrastructure and can be used for coarse particle processing are considered. Finally it addresses the issues associated with the return of waste to mined voids.
