| Since June of this year. The Korea Tungsten Mining Company has been constructing a metal processing complex at Yongdongpo, industrial province of the capital city of Korea. The principal facilities of this complex are Tungsten Processing plant, Tungsten Carbide plant and Bismuth refining plant. In addition to these plants, various processing facilities of Ferro Tungsten, Bismuth alloy, Bismuth Salts, Molybdenium. Tellurium and Selenium are considered as immediate expansion objective of the said complex. In Tungsten processing plant the company produced synthetic scheelite will be converted to the ammonium para-tungstate(A.P.T.) of which is obtainable from tungstic acid(H₂WO₄). This acid can be derived from Hydro-Chloric acid digestion of synthetic scheelite. Some portion of this A.P.T. will be turned into Tungsten Metal powder by hydrogen reduction method. In Tungsten Carbide plant, Tungsten Carbide tipper tools would be initial product and latter it would broader to Rock percussion drill bits and wire drowing dies. The Bismuth refining plant will produce high purity Bismuth Metal(99.99% Bi) from crude Bismuth concentrate(30% Bi). There are of course, some obstacle ahead of these projects. The most significant one is the marketability of its forthcoming products. Their present domestic demand are very much limitted due to the weaker machinery industry of Korea. Thus increase the weight of foreign market, particularly Far East Asian countries, onto the Fruitful operation of this complex. |
