Show PLATINUM IX 1010 Preliminary estimates based on practically complete returns made to the United States Geological Survey, Department of the Interior, by domestic do-mestic refiners of platinum indicate that in 1016 approximately 488 ounces of domestic crude platinum (about 74 per cent metal) were refined, re-fined, producing 172 ounces platinum, plati-num, 84' ounces of iridium, and 113 ounces of iridosmine, and that 10,118 ounces of South American crude platinum, about 88 per cent pure, were refined. The platinum metals produced by refining cru.de placer platinum, of both foreign and domestic origin, amounted to 8,943 ounces platinum, 235 ounces iridium, 199 ounces Iridosmine, Ir-idosmine, and iS ounces palladium. Refiners of copper matte and gold bullion report a production from foreign for-eign and domestic material of 2,556 ounces platinum, 100 ounces Iridium, and 2,746 ounces palladium. About half of this output was produced from domestic materials. The total production of new platinum plati-num metals in 1916 was about 11,-500 11,-500 ounces of platinum, 335 ounces iridium, 200 ounces iridosmine, and 2,765 ounces palladium. The scrap platinum metals sold in the United States in 1916 amounted amount-ed to approximately 49.400 ounces of platinum, 980 ounces iridium, and 2,000 ounces palladium. |
