Structure of the mineral industry

The Government, a private-sector company, and a Japanese company formed a joint venture to produce ferrosilicon and other alloys. Cement production also was under the control of the Government. The Department of Geology and Mines under the Ministry of Economic Affairs has two divisions: the Geological Survey of Bhutan and the Mining Division. The latter is responsible for the inspection and regulation of various
