Selecting Suitable Environmental and Economic Indicators for Flotation Performance
The environmental and economic sustainability of froth flotation is dependent on effective management,which in turn improves the performance of a concentrator. In economic terms this means improved recovery of valuable minerals,in environmental terms this means effective management of acid generating tailings. Three indicators were selected to measure the performance of an integrated flotation system. The system consists of two stages of flotation;valuable mineral flotation followed by environmental desulfurisation by froth flotation.The suitable indicators were selected based on their fulfilment of four attributes. An attribute is a desired aspect of an indicator. The four attributes were: comprehensive,relevant,sensitive and quantitative.Two environmental indicators and one economic indicator were selected. They represent revenue generation from valuable minerals and environmental cost of management.The suitability of the selected indicators was shown using illustrative scenarios.
