Copper ore is processed by froth flotation to raise the amount of
copper from typically 3% percent in the ore to 30% in a dry powdered concentrate. The concentrate
is later converted to essentially 100% copper metal in a smelting furnace or using electrolytic processes.
As a guide for modelling these steps with Trainz industries, assume that 100kg of copper ore will produce
10kg of copper concentrate, which in turn will yield 3kg of copper metal.
