Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy.

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

When processing copper through heap leaching, vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called "overburden." In areas where there are high concentrations of radionuclides in the rock, overburden may have some enhanced radioactivity, but not enough to mine and process.
