Why are copper mines so big?

Copper mines are usually large because copper deposits tend to be spread out over a wide area. To make mining economically viable, large-scale operations are needed to extract enough copper ore. Additionally, the size of the mine allows for more efficient extraction and processing of the copper ore.

How does the scale that forms copper is heated differ from the copper?

The scale that forms on heated copper is typically a layer of copper oxide, which is a compound of copper and oxygen. This scale is a darker color than the original copper metal. The scale is also more brittle and can flake off easily compared to the ductile and malleable nature of the copper metal itself. Additionally, the scale may provide some protection against further oxidation of the underlying copper metal.
