The Environmental Profile Of Platinum Group Metals

The Environmental Profile Of Platinum Group Metals

The extraction and refining of pgms is a capital, energy and labour intensive process which, like all mining activities, has an impact on the environment. When assessing the impacts of pgm production it is, however, essential to examine the full life cycle of the metals in order to acknowledge several important offsetting factors.

Were committed to serving the resources and energy sectors. Its what we do. And its all we do. Its this attention from our people, some 54,100 of them, that allows us to deliver EPCM solutions across the value chain, for the entire project life cycle. We have helped move almost a billion tonnes of iron ore, from mine to port.
