Oct 13, 2023 · Platinum is typically found in association with other minerals, such as sulfides of nickel, copper, and iron, in ore deposits known as platinum group element (PGE) deposits. Platinum ore deposits can form through various geological processes, including magmatic, hydrothermal, and placer deposits.

Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg /kg.

The catalytic properties of the six platinum group metals (PGM)– iridium, osmium, palladium, platinum, rhodium, and ruthenium – are outstanding. Platinum's wear and tarnish resistance characteristics are well suited for making fine jewelry.

Oct 30, 2020 · Native platinum is isostructural with all copper group elements (Au, Ag, Cu) and of course with other platinum group elements (Pd, Ir, Os, Rh) - but not with iron. The small amounts of iridium (Ir), osmium (Os) and rhodium (Rh) are common impurities in the native platinum, less common are gold (Au) , nickel (Ni) and copper (Cu) impurities.

Oct 10, 2023 · Platinum is coveted for its rarity, resilience and versatility. Its scarcity makes the noble metal exclusive and valuable, while its resistance to corrosion and ability to withstand extreme conditions make it ideal for various industries.

May 10, 2018 · Platinum can be found in alluvial placer deposits in flakes or in small grains. Positive identification often requires laboratory analysis. Most PGEs originate in magnetic ore deposits. These formed as a result of magma cooling and crystallizing into sulfide globules. Magma formed various intrusions into shallow parts of the earth's crust.

Jan 26, 2021 · Platinum group metals or elements commonly refer to ruthenium, rhodium, palladium, osmium, iridium, and platinum and will be referred to as PGEs in the present paper. These metals are present in a very wide range of platinum …

Oct 15, 2023 · Platinum minerals are commonly associated with nickel and copper ores, and the primary mineral source for platinum is often the mineral sperrylite (PtAs2). Sperrylite is a platinum arsenide mineral that is one of the few naturally occurring minerals containing platinum as its primary component.

This chapter describes platinum-group ores and minerals and discusses how they are made into flotation concentrates enriched in platinum-group metals, different ores and their respective compositions. These concentrates are later smelted and converted to a molten sulfide matte.

Ferroan platinum differs from Isoferroplatinum and Tetraferroplatinum by the symmetry of its unit cell. Described by Hausman in 1813 from Colombia. A rhodian Platinum with 4.6% Rh. Non-magnetic to distinctly magnetic when rich in iron. No information on health risks for this material has been entered into the database.
