Millions of tonnes of iron ore from scores of small mines...are going into building China's gleaming, steel and glass office towers and stadiums for the 2008 Olympic Games...The unlicensed mining business is a shadowy world...In mid-March, the office of the Hospet tehsildar (revenue official) had finally cracked down on illegal mines, serving notices to 122 farmers for leasing their lands without permission. "Strict action will be taken," deputy tehsildar Venkangowda Patil said. The threatened punitive action follows pressure from the handful of big mining companies, and Indian steelmakers who have been shamed by reports of child labour in the iron ore mines in the Hospet-Bellary-Sandur belt...Among the big exporters here are the state-owned National Mining Development Corporation, V.S. Lad and Sons and Kariganur Mining Mineral Industry.
