Chalcopyrite
Chalcopyrite is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green-tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides, aIOCG ore deposits containing economic quantities (highly profitable) of both copper and gold originate from the Precambrian. Larger deposits with >100 tons of resources occur near Paleoprotozoic and Archean cratons. These large deposits formed by mantle underplating impacts to metasomatized lithospheric mantle, and smaller deposits form by tectonic settings replication of this proceIron oxide copper gold ore deposits

Minerals with Iron Which Minerals Have the Most
In that time frame, it has been found that minerals with larger quantities of iron include pyrite, magnetite, chalcopyrite, hematite, goethite, limonite, greenalite, and siderite. The minerals with the highest iron content will be magnetite, hematite, goethite, and limonite. These minerals range in about 60% to 70%+ in iron content.Of North Korea’s identified mineral resources, deposits of coal, iron ore, magnesite, gold ore, zinc ore, copper ore, limestone, molybdenite, and graphite are larger than other mineral commodities. These mineral resources all have the potential for the development of large-scale mines. Table 1 shows North Korea’s mineral resources data.The Mining Industry of North Korea Nautilus
