Ore is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining and is therefore considered an ore. A complex ore is one containing more than one valuable mineral.
The Southeast Missouri Lead District, commonly called the Lead Belt, is a lead mining district in the southeastern part of Missouri.

Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes, particularly in the North and South Hamgyong Province and Chagang Province. 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, Canada, Egypt, and South Korea.
