An ore is a rock in which a valube or useful metal occurs. The more demand a certain rock has the more value it has thus it will be more valuble to be mined. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal.

Abstract. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment. Copper mining produces extensive mine wastes and tailings and Cu smelting emits approximately Mg of S per Mg...
Effects of Gold Mining on the Environment. Although its price fluctuates, gold regularly sells for more than 1,000 per ounce. Gold nuggets are popular among collectors but are rare; most gold is found as small particles buried in gold ore. Mining just an ounce of gold from ore can result in 20 tons of solid waste and significant mercury and cyanide contamination, according to Earthworks.
