      “Ore” is a fine white clay like sand created by the weathering of a Granodiorite body. Weathering takes place to depths of 75 to feet; little overburden, shallow pits. Ore is excavated without drilling or blasting using contract miners utilizing 3 yd3 excavator and 30 ton trucks. Short haul to process facility minute cycle. Palladium was added to the Platinum group in It was used extensively in jewelry as early as and grew in popularity when Platinum was declared a strategic metal for military use in World War II. Palladium is a naturally white and lustrous metal. It weighs less approximately 42% less than Platinum. Investors Take a Shine to Platinum, Palladium. May by Associated Press. Move over gold and make way for platinum and palladium. Investors are taking a shine to these lesser-known precious metals as their prices rise.

Stillwater Mining Palladium 1 Troy oz bullion round in hard plastic case with serial numbered assay card. North American Palladium Ltd. is a former Canadian mining company that operated between and and that since operated the Lac des Iles mine in the Lac des Îles igneous complex of the Thunder Bay District of company primarily mined and explored for palladium but also for gold.

Platinum, silver, nickel, and copper are mined as arters: Toronto, Ontario. The Mimosa ore is characterised by an unusually large amount of talc, which often causes problems during the flotation of the PGM minerals due to the fact that talc consumes high amount of reagents. Therefore the purpose of the second part of this thesis was to investigate the possibility of removing talc prior to the flotation process.
