Peter C. Lightfoot, in Nickel Sulfide Ores and Impact Melts, 2017. Platinum group elements and gold. PGE and Au data are often averaged and expressed as concentrations in 100% sulfide, and they are then plotted by normalizing the concentrations in 100% sulfide to the average concentrations in C1 chondrite (Naldrett, 1984c).

At Russias Norilsk and Canadas Sudbury deposits, the metal and other PGMs are extracted as by-products of nickel and copper. Extracting platinum from its ore is both capital and labor intensive. It can take up to 6 months and 7 to 12 tons of ore to produce 31.135g of pure platinum.

Aug 21, 2020 Platinum is always found alongside other PGMs. In South Africas Bushveld complex and a limited number of other ore bodies, PGMs occur in sufficient quantities so as to make it economical to exclusively extract these metals whereas, at Russias Norilsk and Canadas Sudbury deposits platinum and other PGMs are extracted as by-products of nickel and copper.

Feb 26, 2010 The proportion of waste tends to increase the more valuable the product metal, because high value products (such as gold or platinum) can justify the cost of extracting and processing low-grade ores. In many cases, the nature of the materials in a natural deposit, metal ore on the one hand and gangue on the other, may be so different in ...

Magmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without ( ) platinum-group elements (PGE), account for approximately 60 percent of the worlds nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions.

Platinum is even worse than gold. Copper is surprisingly bad environmentallypartly because its increasingly scarce (every pound of copper these days requires 100 1,000 pounds of ore), and partly because its surprisingly toxic in rivers and lakes.
