Mining in South Korea
Principal minerals include coal, gold, silver, tungsten, talc, and iron ore. With limited natural resources, the nation is developing overseas mining interests to meet its needs.
Mining in North Korea
About 80 to 90 percent of the Korean peninsula’s important mineral deposits, especially coal, iron ore, lead, zinc, tungsten, and fluorite, is found in North Korean territory. The main coal mines are located north of Pyongyang, more than half of the nation’s electricity output is generated by coal-powered plants. Iron ore is a major export item, followed by steel, lead, zinc, and cement.
Iron ore processing process
First, ore crushing and grinding: concentrator generally coarse broke, broken in three sections of broken and fine crushing of iron ore crushing process. Rough broken 1.2m or 1.5m multi-cycle crusher, in breaking with 2.1m or 2.2m Standard cone crusher, fine break by 2.1m or 2.2m short head type cone crusher. Through the thick broken ore, the block is no more than 1m, and then through the medium and fine crushing and screening into the small particle size of ore 12mm to send the final product in the grinding slot.
Iron ore crusher machine
The most commonly used iron ore crushers are jaw crusher, impact crusher, cone crusher and mobile crusher. Jaw crusher is used in primary crushing station. Impact crusher is generally used as fine iron ore crusher after jaw crusher, and can crush iron ores into smaller size to separate ores from stones and sands. Cone crusher is the most common fine iron ore crusher machine. Mobile crusher is the most convenient iron ore crusher machine used in the iron ore beneficiation plant. It is the crushing unit including crushing, screening machine and belt conveyor.
Iron sand and Limonite ore
Limonite is a minor ore of iron. It is also used as a stain in the paint industry. The widespread and common hydrated iron oxide mineral limonite, Fe(OH)ánHMO, is a minor ore of iron and a source of ocher and umber pigments.
Iron sand is a type of sand with heavy concentrations of the metal iron. It is typically dark grey or blackish in colours. It comprises mainly magnetite, Fe3O4, and as such is attracted to magnets.
