The major import minerals of South Korea are copper ore, lead-zinc ore, iron ore, manganese ore and molybdenum ore. Oversea resources development of South Korea have 92 projects in 14 nations of Asia, 29 projects in 10 nations of America and Europe, and 14 projects in 9 nations of Middle Asia and Africa. But, most projects of them are found in Australia, China, Mongolia and Indonesia. The most projects of the Australia, China and Indonesia are interested in coal and a little projects of them have manganese, iron, lead-zinc, nickel, copper, gold, molybdenum, rare earth elements and uranium. The most projects of the Mongolia are interested in gold and rare earth elements. Representative ore deposits models of metal resources are Orogenic lode deposits, Volcanogenic massive sulphide deposits, Porphyry deposits, Sedimentary exhalative deposits, Mississippi valley type deposits, Iron oxide copper-gold deposits and Magmatic nickel-copper-platinum group element deposits based on global distribution, reverses and grades of their deposits models. If oversea mineral resources will be examined the mineral reserves, mineral mine production and ore deposits models of nations and then survey and investigate of mineral resources, we may be maintained ore body of high grade at survey area and decrease the investment risk.

한국의 금속광산은 일제시대에 금광산을 중심으로 본격적으로 개발되어 1943년 산금령시에 1,522개 광산이 가행되었다. 최근까지 1990개 광산이 개발된 것으로 알려지고 있으며 2002년 말 현재 7개 광산만이 가행되었다. 1960년대까지 국내 광산은 금, 은 동, 연아연, 철, 중석 등을 중심으로 활발히 가행되어 주요 외화 획득원으로 중요한 위치를 차지하였다. 그 이후 산업발전에 따라 수요는 증가세를 보인 반면 가행광산과 생산량은 매년 감소하여 최근 금속광물자원 자급도는 0.21%로 미미한 수준이며 수요의 대부분을 해외에 의존하고 있다.

This article aims to summarize the scrap recycling status of gold, silver, platinum and palladium from foreign countries by courntires and industries in order to utilize the data for securing the raw materials of the domestic urbanmining industry. The amount of gold from scrap has shown a tendency to decrease in countries other than China, which is attributed to the large imports of scrap containing gold in China. The industry demand for gold is the highest in electronic products, but demand is decreasing. The amount of scrap recycling in silver has declined in other regions compared to those in Europe, indicating that the world's overall scrap recycling volume has declined. Production and demand from scrap of platinum and palladium are mostly for catalysts and have been steadily increasing until now. However, it is expected that the amount of waste catalysts in automobiles will decrease with the increase of electric vehicle use.

This paper investigates how oil price changes have an impact on the Korean manufacturing production activities. For this investigation, we use a structural VAR motel to estimate impulse response functions of industrial production, producer price and export price to an oil price increase over manufacturing industries. It finds that in most manufacturing industries, an oil price increase leads to decreases in industrial productions and domestic prices except energy intensive industries, but to increases in industrial export prices except non-metallic (26), computers and offic machinery (30), electronic components, radio, television and communication (32) industries. This result explains that an oil price increase makes negative impacts on the manufacturing production activities not only through demand slowdown in the domestic markets but also through supply contraction in the export markets.

지난 2월 산업자원부에서 발표한 ''''2004년 항공우주산업 육성계획''''에 의하면 대외 의존적인 국내 항공우주산업의 자립 기반을 구축하고 수입유발적인 항공우주산업의 고부가가치 창출과 무역수지 개선을 위하여 510억원 규모의 자금을 국내 항공우주 산업계에 지원하게 된다. 이 중에서도 항공우주 핵심 부품·소재 기술개발에 120억원 규모의 지원금을 배정함으로써 이 분야에 대한 육성이 앞장서고 있다. 또 국방부는 KMH나 E-X 사업에서 총 계약금의 30%를 국내참여분으로, 해외참여분 70%의 30%를 절충교역분으로 규정함으로써 국내업체의 참여를 보장하고 핵심 기술 및 부품의 국산화 개발을 적극적으로 추진하고 있다. 이와 같은 추세를 볼 때 항공우주분야에서 접목시킬 수 있는 기술기반을 가진 업체들의 발굴이 절실하다. 이러한 맥락에서 (주)AKA가 알루미늄·티타늄 계열의 성형기술을 항공우주 및 방위산업에 접목시키고 있는 기술적인 노력은 새롭게 평가받을 만하다.

Gallium is an important material and is used by industry of oxide semi-conductor and LED chip. However, the most of the gallium-containing waste resources became outflow abroad and the most of which is imported from oversea by following technical problem and low circulation rate. In this research, the recovery of high purity Gallium metal from Gallium scrap, which containing about 30% of Gallium, was investigated by using hydro-metallurgical process. As pretreatment, the Gallium scrap was pulverized and leached by strong acid such as hydro chloric acid. At the leached solution, Indium was separated as an Indium sponge by substitution reaction and then Gallium and Zinc hydroxide separated and filtrated using strong alkaline solution such as sodium hydroxide by precipitation method. Also, Gallium metal and Zinc metal was recovered by electrowinning method. To make an electrolytic solution, Gallium and Zinc hydroxide was leached by strong alkaline solution. Finally, High purity Gallium metal was recovered by vacuum refining process to remove the Zinc impurity.

The status of waste generation and recycling in 32 countries in the European Union (EU), Japan, and the United States was investigated and summarized to encourage overseas market expansion for domestic urban mining industries. Among the 32 EU countries, Germany has the highest amount of material consumption and generates the largest quantity of waste. Minerals such as mine and soil wastes constitute the largest type of waste in the EU. With respect to waste treatment techniques, landfill and recycling are applied to 39% and 38% of the waste, respectively, implying the necessity to promote recycling. Japan's total waste generation declined recently to less than 400 million tons. The largest amount of waste is generated by the manufacturing industries. The proportion of total recycled waste is estimated to be slightly over 50%, but the proportions are greater than 90% for metal scrap and 60% for waste plastics. The amount of waste produced in the United States recently exceeded 265 million tons; 52.1% of the waste is landfilled, while only 25.1% is recycled. Therefore, the recycling industry has to be developed further.

When greenhouse gas mitigation policies are implemented, energy intensive manufacturing industries are influenced much due to an increase in cost. However, industries that have price setting power are damaged less by the policies. Therefore, this paper analyzes vulnerability of energy intensive manufacturing industries to the policies by measuring price setting power of the industries. We analyzed price setting power model through ECM, employing the import prices and wages as independent variables. The industries that their prices react to import prices are price takers, which their prices are determined by rival's ones. On the other hand, the industry that their prices react to wages that mean domestic cost are price setters, and they will be less vulnerable to the policies. In addition, fluctuation of energy prices would be reflected in import prices because it influences other countries than my one. Thus, we employed energy prices as control variable to measure the net effects of import prices. As empirical results, petroleum products, chemical products, non-metallic mineral products, textiles, and motor vehicles sector have price setting power, so the industries have competitiveness on greenhouse gas mitigation policies.
