The key metric is ore grade: the proportion of a rock that contains the element(s) that are the target of extraction. For copper, the ore grade is typically about 0.5%, for example. So, to obtain a tonne of the element, roughly 200 tonnes of ore must be extracted, apart from any waste rock and overburden.

Nickel is a hard silver-white metal with a high melting point and can withstand very low temperatures. Nickel is rarely found in the earth in its pure form; it mixes well with other metals to make many useful alloys. Nickel is malleable and ductile (can be beaten and drawn out into a wire) and is rust-resistant.
