True when we look at mining solely as a raw material exporter. However, the social multiplier of mining is very significant for South Africa with a reported dependency ratio of about 10:1 (The downstream value addition from mining). In addition to the direct contribution, mining also has an indirect multiplier effect on the gross domestic product, giving rise to a “real” contribution to South Africa’s GDP of between 15-20%.
e.g. mining sector buys services from manufacturing, automotive, consulting, financial , electricity and water inputs. Also mining fuels the country's economy in terms of primary energy needs. It is estimated that for every direct mining job, two jobs are created. This is likely to be true of you consider the growth in Brazil, Chile, Australia attributed to resource sector.
We are not as dirty as people like to think....
