ore

An ore is a natural combination of minerals from which metals can be extracted at a profit. Originally the term ore was applied only to metallic minerals, but the term now includes nonmetallic substances that have been deposited in rock after its formation. All metals come from ore deposits found in the Earth's crust.

In addition, gases and liquids are excluded by a strict interpretation of the above definition of a mineral. Ice, the solid state of water (H 2 O), is considered a mineral, but liquid water is not; liquid mercury, though sometimes found in mercury ore deposits, is not classified as a mineral either.

Mercury: Facts

Introduction Mercury's surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C). Despite its proximity to the Sun, Mercury is not the hottest […]

5. Where do the world's supplies of mercury come from?

Despite a decline in global mercury consumption (global demand is less than half of 1980 levels), supply from competing sources and low prices, production of mercury from mining is still occurring in a number of countries. Spain, China, Kyrgyzstan and Algeria have dominated this activity in recent years, and several of the mines are state-owned.
