dc.descriptionPlatinum (in reality the entire platinum group of elements) has been and continues to be the subject of much discussion among miners in Arizona. Do the metals exist in Arizona? Are they in mineable quantities, if they do exist? Are they now produced? What is the significance of the reports of theft of platinum from Inspiration Copper Company? The platinum group of metals comprises platinum, palladium, rhodium, iridium, osmium, and ruthenium, of which platinum is the most important. Of these metals, osmium is generally alloyed with iridium. The platinum group metals occur chiefly as natural alloys of various proportions and to a much lesser extent as sulfides and arsenides. All of these metals are rare and expensive. They possess individual properties that make them uniquely attractive for certain uses in highly developed technology and for use in jewelry and for decorative purposes. Platinum and palladium are the most abundant and most widely used of the group; the other four metals are mainly used as alloy modifiers with platinum or palladium. The high melting points, corrosion resistance, and catalytic properties of these metals have many industrial applications. There has been minor past production of the platinum group metals from California and Alaska, but present domestic production, mostly as a by-product in the refining of copper, is insignificant when compared with domestic consumption.
