In the gold leach process, calcium in the solution may be the result of calcium ions already present in the water or from the addition of lime for pH adjustment. Carbonate can be contributed by freshwater addition or by adsorption from the air.
Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation. Calcium phosphate (also known as hydroxyapatite) is the mineral component of bones and teeth and is a particularly good example of how organisms fabricate 'living' composite materials.
