2007-2-10  The mining and production of gold is indeed an ancient human tradition and presently occurs all over the world. The history of gold mining is commonly associated with social, political, economic and environmental impacts, some of which can lead to significant negative costs. In recognition of the potential and actual impacts of gold mining, the industry has in recent years been moving towards a more sustainable framework, primarily through the ‘Minerals Mining and Sustainable Development’ report presented by the global mining industry framework at the Johannesburg Earth Summit in 2002. Over the past decade there has also been a rapid increase in the publication of sustainability reports by mining companies, in which they report their social, economic and environmental performance. The prediction of future sustainability issues associated with gold mining, however, must be cognisant of historical production trends as well as the relationships between key aspects such as energy, water and cyanide consumption and greenhouse emissions, herein termed “resource intensity”. This paper compiles the available data on gold mining
