Ore deposits are metallic minerals in sufficient volume and concentration to be extracted economically. They are generally formed through one of three geological processes. Magmatic ore deposits are concentrated within a body of igneous rock. Elements that were once widely dispersed in low concentrations in the magma become concentrated as they crystallize....
