Mining in North Korea
Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes (second largest in the world), particularly in the Hamgyeong-do and Jagang-do provinces. However, often these cannot be mined due to the acute shortage of electricity in the country, as well as the lack of proper tools to mine these materials and an antiquated industrial base. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Mining joint ventures with other countries include China, Egypt, and South Korea. China is North Korea's leading trade partner for minerals (twenty mining projects reported), followed by South Korea and Brazil.
North Korea has reserves of more than 200 mineral types distributed over 80% of its territory with ten reserves recording large deposits of magnetite, tungsten ore, graphite, gold ore, and molybdenum. Among the largest resources with more than 2 million tons of estimated reserve are: Zinc which tops the list with 21.1 million tons of estimated resource; followed by non-metallic resource of 21 million tons of limestone and magnesite 6 million tons; and other mineral sources such as iron 5 million tons, anthracite 4.5 million tons, copper 2.9 million tons, barite 2.1 million tons, gold and graphite also 2 million tons each.
The Mineral Industry in the country is structured under three broad sectors namely, coal mining, ferrous and nonferrous metals mining, and processing sector and industrial minerals mining and processing sector. All these sectors are owned by the central government and it is also reported that the mineral industry supports the country’s military budget.
North Korea is thought to have tremendous potential rare metal resources, which have been valued in excess of US$6 trillion by the South Korean national mining company. There is much investment from Chinese mining companies, with an estimated $500 million investment in the last 11 years. 41% of all Chinese companies trading in North Korea are involved in mining.
The Korea General Zinc Industry Group is a North Korean mining and industrial group headquartered in Pyongyang. The organization produces zinc, lead, base bullion, lead concentrates, zinc concentrates, cadmium, arsenic, zinc residues and copper concentrate for export and domestic use.
The Geomdeok Mine, located in Geumgol-dong, Dancheon-si, Hamgyeongnam-do, has been in operation since 1932 and is the largest zinc mine in East Asia. It has seven mine blocks extracted through 10 mines. It has annual capacity to handle 10 million tons of zinc ore. Are recovered. Conventional flotation methods are adopted to extract lead and zinc concentrates. Other products from the mine are sphalerite, chalcopyrite, and galena.
In gold alone the nation is estimated to hold around 2,000 metric tonnes of reserves, with a current value of around $100 billion. Other available resources include iron, with 5 billion tonnes of 50% iron-content ore in reserve, nickel, with 36,000 tonnes of the pure metal, and zinc metal, with around 21,100,000 tonnes.
The Daebong Mine, located on the border of Gapsan and Woonheung in Yanggang Province, produced more than 150 kilograms (kg) (4,823 troy ounces) of gold annually. Further improvements are proposed in this mine with Chinese investment under a package of offer of mineral rights in exchange for capital investment in the mine.
The Sangnong Mine, in the Dancheon district of Hamgyeongnam-do has been in operation since 1956 and is an underground mine. The mine also extracts pyrite, chalcopyrite, magnesite, native gold, and native silver. In 2008, the annual production was reported as 290,000 tons of concentrate at a grade of 30g/t. To process the low-grade concentrate of the Sangnong Mine, the Dongdae Custom Mill Plant (located in Dancheon city) has been established. This plant has processed twenty million tons of tailings and the waste piled up in the yard of the plant has still a gold pf grade of 1.44g/t.
The Holdong Mine in the Holdong labor district in Yeonsan-gun, Hwanghaebuk-doce has been in operation since 1893. Gold and other ores are found in a strike of 1,200 metres (3,900 ft) strip. The plant has capacity for annual handling of 2 tonnes of gold, 2.5 tonnes of silver, and 80,000 tonnes of copper concentrate. In 1991, the mine recorded a production of 0.85 tonnes of gold, 1.674 tonnes of silver, and 893 tonnes of copper concentrate.
The DPRK is estimated to hold a total amount of 2.1 million metric tonnes of copper metal. The Korea Mining Development Trading Corp. (KOMID) was involved in a joint-development project with a Chinese firm in the development of a copper mine in Hyesan. However, KOMID was blacklisted by the United Nations in 2009 subsequent to North Korea's April 5 rocket launch. This resulted in a halting of facility construction at Hyesan. The Hyesan copper mine, located Yanggang Province would be operated by the Hyesan-China Joint Venture Mineral Co.
The Hyesan Mine, located in Masan-dong, Hyesan-si, and Ryanggang-do, has been in operation since 1970 and is the largest copper mine in the country. It was flooded and hence closed from 1994 to 2009 and has been partially reopened, after bailing out water, since 2010. Other products from the mine are chalcocite, chalcopyrite, galena, and sphalerite. The plant has a capacity to handle 1,200,000 tons of copper ore annually. According to a 1993 report, the mine produced about 90,000 tons of concentrate of 16% grade of copper.
Iron ore mining
Musan Mine, located at Musan-gun, in the Changryeol labor districts and Hamgyeongbuk-do, is being operated by Mitsubishi Mining Company of Japan since 1935. The ore is found a strike stip of 1200 m and is operated through nine blocks and extraction is by open pit method. Its iron ore handling capacity is 10 million tons per year. The annual production is reported to be 2 million tons of iron concentrate of 65% grade. After processing at the Gimchaek Steel Mill, iron is exported to China.
The Oryong Mine, located in Ryongcheon-ri, Hyeryeong City, in Hamgyeongbuk-do, has been in operation since 2007. Iron ore is embedded in granite formations as magnetite, hematite, and ilmenite in the Musan group and Liwon-am group of rocks, and the ore extracted in directly transported to China without milling. The ore exported in 2007 was of the order of 3,000 tons.
Jeongchon Mine is a graphite mine located in Jeongchon-gun, Hamgyeongnam-do and the ore is found in strike length of 700m. Mining operation was started here in 2006. It is an inter-Korean project with South Korea getting a share of 50% of the extracted graphite.
Magnesite in the Tanchon area, a very large resource, has been under extraction since 1980 from the Taehung Youth Hero Mine and the Yongyang Mine, and the former mine is reported to be operating to its full capacity.
Daeheung Mine, located in Daeheung-dong, Dancheon-si, and Hamgyeongnamdo comprising four mine blocks has been in operation since 1982. It is reported to be the largest magnesite mine in the world. Magnesite ore is found in a strike of 1600 m and has been extracted since 1982. Both open pit and underground mining are done in these mine blocks and there is a total capacity to extract magnesite ore of 600,000 tons per year. In 2006 the production reported was 230,000 tons of magnesite of grade of up to 46.5 percent of MgO.
Nonferrous metal mining
In 2005, it was reported that Kimduk Combined Mining Enterprise was the country's largest nonferrous metal mine.
In addition to its metal resources, North Korea is also abundant in coal and limestone (with 100 billion metric tonnes), valued to be worth some US$9.7 trillion. In particular the purest form of coal, anthracite, is especially abundant, with over 4.5 billion tonnes in reserve.
Jikdong coal mine is an anthracite coal mine located in Jikdong, Suncheon-si, Pyongannam-do where underground mining operation started in 1997. It has capacity to handle 1 million tons of coal per year. The coal is transported by trucks directly to run the Dongpyeongyang Thermal power plant.
Gogeonwon Mine is also an anthracite coal mine located in the Gogeonwon labor district, Kyeongwongun, Hamgyeongbuk-do and has been in operation as underground mine since 1920. It has a capacity of 1 million tons and the coal mined is sent by trucks to run the Cheongjin Thermal Power Plant and the Seongjin Steel Company.
