    Metal Reactivity and Extraction. The way in which a metal is extracted depends on its reactivity. The more reactive a metal is the harder it is to extract. The harder a metal is to extract, the more it costs to extract. For example electrolysis is more expensive than heating with carbon because of the cost of electricity. Therefore, the more reactive a metal
