Ore study of economic geology, or ore genesis. The classifications below are typical. The basic extraction of ore deposits follows these steps: Ores (metals) are traded internationally and comprise a sizeable portion of international trade in raw materials both in value and volume. This is because the worldwide distribution of ores is unequal and dislocated from locations of peak demand and from smelting infrastructure. Most base metals (copper, lead, zinc, nickel) are traded internationally on the London Metal Exchange, with smaller stockpiles and metals exchanges monitored by the COMEX and NYMEX exchanges in the United States and the Shanghai Futures Exchange
Ore Mountains animals that have been found at higher altitudes of the Ore mountains are otherwise only known from more distant places in the Sudeten mountains or the Alps. After conditions improved, once displaced species such as Eagle owls and Black storks have returned in the early 21st century. The German part of the Ore Mountains is one of the major business locations in Saxony. The region has a high density of industrial operations. Since 2000, the number of industrial workers has risen against the Germany-wide trend by about 20 percent. Typical of the Ore Mountains are mainly small, often owner-managed, businesses.
