Other minerals found with platinum in alluvial are iridium and osmiridium. The Ural deposits contain on the average 5 dwt. of platinum per ton, but much richer deposits are The most -productive of the Ural are those occurring along the Iss and rivers, and these are said to about 80 per cent, of the Russian

In western Colombia, South platinum-bearing gravels occur in the Choco district ; and platinum is found to a small extent in the gravels of the Barbacoas district south. Platinum is found in at Fifield, in New South Wales; in the gravels and beach-sands of California and in the United States; in the placers of Bay at Seward peninsula, Alaska; and in of the Tulameen and Similkameen rivers in Columbia.

Palladium occasionally occurs with gold. In Brazil, palladium gold in a limestone to the contact of an igneous rock.

In platinum and palladium are obtained the mattes obtained by smelting the ore of Sudbury, in Ontario. The high-grade contain from 0.2 to 0.5 oz. of platinum per ton. The platinum occurs in the copper-nickel ore as sperrylite, embedded in Platinum-bearing nickeliferous pyrrhotites are to occur elsewhere, as in the Bushveld of the Insizwa Range of Cape in South Africa.

Considerable amounts of platinum are from the Sudbury mattes, but the deposits yield an even amount. Palladium can be found as a metal alloyed with and other platinum-group metals in deposits of the Ural Mountains, Ethiopia, North and South Platinum is reported to occur in the of Honda, Malaga province, where there is an abundant of serpentinized peridotites.

The platinum is associated with and is concentrated in the basal layer of the gravels. Platinum is associated gold and osmiridium in the island of

In the US, sperrylite, the same mineral in the superficial zone of some of the mines, has also been in the Rambler mine in Wyoming it occurs in copper ores, chalcopyrite and covellite. Here it is of igneous origin and forms a in a dioritic rock. Much is also present in the Rambler Platinum and palladium are found gold in ores of the Boss in the Yellow Pine district, County, near Moapa, in Nevada.

The ore minerals here are associated quartz that replaces along vertical fractures. porphyry intrudes the dolomite, and no igneous intrusive rocks are in this region. The ore is oxidized and a bismuth-bearing variety of plumbojarosite. All at the Boss Mine are found in division.

The gold is rough, and spongy, the palladium-platinum appears as black grains. The platinum were probably contained in the sulphides and most likely been concentrated by solutions in they were present in suspension. Neither the Rambler nor the mines have been sources of platinum.

At many copper mines the western US, platinum and palladium are in the electrolytic refining of copper by processing the mud that forms in where blister copper is The most important source of group metals in the US has been at Bay in Alaska. These placer produced about 545,000 ounces by dredging between and 1975.
