PGM extraction and refinement is also a capital- and labor-intensive process. According to the International Platinum Group Metals Association (IPA), it can take as long as six months from initial mining activities to produce the final metal. PGM ore is mined typically underground but sometimes in open-cast pits. The process from extraction to

Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the
