Student at Kyonggi Technical High School in Seoul study water flow using a movable channel. The channel is part of $20,000 worth of equipment furnished to the school by the United Nations Korean Reconstruction Agency (UNKRA) for a new hydraulics laboratory dedicated on 14 October 1958. The laboratory, the only one in South Korea will afford training for civil engineering students specializing in irrigation, flood control, land reclamation and the like. Altogether UNKRA has provided this vocational high school with three one-story shop buildings, a three-story building in which the new hydraulic laboratory is located, at a total cost of $159,000 plus another $122,000 in equipment and supplies.

Old and new at Changhang Smelter. Old plant and new equipment are being dovetailed into a dramatic rehabilitation program at Changhang, Korea’s only smelter and ore refinery. The modernization of the smelter, which was undertaken by the United Nations Korean Reconstruction Agency (UNKRA) at a cost of over $1,550,000 in order to meet the increasing output of the metal mines and to assure for Korea more favorable foreign exchange for her metal exports, is now in full swing. Every effort is being made to utilize the existing resources of the smelter to supplement the new equipment that is being brought in.

A curious by-product of the foundry are slag bricks made form molten slag poured into moulds. The bricks (stacked behind) measure approximately eight by four by two inches and are used in all construction work on the foundry. They weigh about 9 pounds and are very durable. The production is 150,000 bricks per month dependent on the weather as they cannot be made under wet or snowy conditions. Bricks not needed for smelter construction work are sold for 70 hwan each.

Portable conveyors, part of the UNKRA imported equipment, screening and handling coal to stock piles. Later these belts will be used to handle the raw ores.

Large-scale production of quality-grade flake crystalline graphite with a carbon content ranging between 87 and 90 percent started in the Republic of Korea in January 1959 at this modern new mill. The mill was built jointly by the United Nations Korean Reconstruction Agency (UNKRA), The Republic of Korea Government and the Shiheung Crystalline Graphite Mining Company of Seoul, which is the end user. Raw ore for the mill is now being mined from surface deposits which covered the hill on the left. The buildings to the right of the picture belong to a small, out-moded mill which turned out a low-grade product.
