Rock samples from about 280 podiform chromite deposits in California and Oregon were analyzed for Pt, Pd, Rh, and Ir by fire assay-atomic absorption and spectrographic techniques to estimate by-product platinum-group element potential of chromite mining. These deposits include ophiolites from the Sierra Nevada, Klamath Mountains, Coast Ranges, and the Canyon …

Platinum Group Elements and Their Isotopes in the Ocean. G.E. Ravizza, in Encyclopedia of Ocean Sciences, 2001 Summary. The PGEs are among the least abundant elements in sea water. The low concentrations of these metals in sea water reflect their generally low concentration in earth surface material rather than uniformly low solubility.

Platinum (Pt) is a rare and valuable metal that is widely used in various industrial applications due to its unique properties. Platinum ore refers to the naturally occurring rocks or minerals that contain significant concentrations of platinum, usually in the form of platinum group minerals (PGMs) and associated minerals. Platinum ore is typically found in specific …

Geology and Mining. There are large deposits of platinum group elements in the Merensky and Upper Group 2 reefs in South Africa ("South Africa"). These deposits were formed from silicate magma intrusions. Immiscible sulfide liquid saturates the magma and attracts PGEs along with copper and nickel (Zientek, 2012).

Significant differences in the proportions of platinum-group elements within a particular layer are only evident on a regional scale.The platinum-group minerals of the middle group of chromitite layers in the Marikana area of the western Bushveld are mainly sulfides and arsenides. Laurite is the most common platinum-group mineral and is mostly ...
