Platinum ore used in this work was obtained from the feed to the primary mill (run of mine) at Anglo Platinum's Amandelbult mine. The ore has a density of 3.47 g/cm 3. The moisture content of the platinum ore was determined by drying a 500 g sample of the platinum ore at 50 °C in an oven, overnight and then the weight after drying was ...Ore processing. The ore obtained from the operations undergoes crushing and concentration at the processing plants located at the mines. Ore is stored in a 3,175t silo before being fed to a SAG mill. Oversize is passed to a ball mill while undersize is cycled to flash flotation circuits.

Milling Platinum Sterling (925) – A New Alloy. A billet of Platinum Sterling 925 (on the right in the picture) was milled out to .15 mm thickness (less than a playing card thick) with absolutely no annealing. This brand new alloy is called Platinum Sterling, and is mostly fine silver with a modifier of Platinum in it (4-6%).The platinum-palladium mineralization was associated with the sulfides which made up about 1 pct of the rock. Microscopic examination of screened fractions of crushed ore showed that most of the sulfides could be liberated at 200 mesh. The Bond Index value for grinding the ore to minus 200 mesh was 16 kW·h/ton. Specific gravity of the ore was 2.8.
