The amount of copper believed to be accessible for mining is 1.6 billion tons. In addition, it is estimated that 700 million tons of copper is available in deep-sea nodules. Mineral-rich nodules of magnesium, copper and other metals are known to form as a product of deep-sea volcanic activity.

2.2.3 Moles. A mole of an element (or of a compound) is defined as containing 6.022 × 10 23 atoms (or molecules). The number, 6.022 × 10 23, is known as Avogadro's number. So, one mole of carbon is equivalent to 6.022 × 10 23 carbon atoms. The scale used to measure atomic mass has changed slightly over time.

In essence, not all minerals are ores, but all ores contain minerals. Ores are classified based on their metal content and the feasibility of extracting that metal. This means that the economic value of the metal and the cost of extraction are key determinants in defining an ore. 8. For instance, aluminum is extracted from the mineral bauxite.
