An engineering firm is designing extraction facilities for four different metallic elements discovered in a newly surveyed mineral deposit: gold, calcium, iron, and tin.
The choice of industrial extraction process depends fundamentally on the relative chemical reactivity of the metal.
Using the reactivity series in Figure 1, state and explain the method chosen to extract each of these four metals.
