Assaying Korea's Mineral Resources

The Republic of Korea has considerable mineral resources. There are rich deposits of gold, graphite and tungsten, as well as of coal; and there is enough lead, copper, bismuth and manganese to merit attention. There seems to be a reasonable prospect of developing mineral exports within a few years to the value of $40 million or $50 million a year. But the full extent of the country's mineral wealth has yet to be measured. The UN Korean Reconstruction Agency (UNKRA) has, therefore, built a mineral assay laboratory with the most modern equipment at Taejon, to test ore samples to assess the commercial value of the mines now in existence and make a proper evaluation, of the new finds.
As one of its jobs, the laboratory periodically analyzes the quality of coal produced in various Korean mines. This picture shows Korean expert Chang Won Pyo and Gerhard Lyckholm, UNKRA chemist-metallurgist from Sweden, measuring the heat content of a sample of coal with a ""Calorimeter"".
