Platinum group metals (PGMs) are often thought of as "exotic". Yet, according to the International Platinum Group Metals Association (IPA), one-quarter of all manufactured goods either contain a PGM or a PGM played a key role in its production. "That isn't surprising given that PGMs are the densest known metals.The versatile properties of this unique group of elements are valued in a ...

Platinum-group elements occur mainly in or near sulphide minerals in an ore deposit. They are typically dissolved in pentlandite [(Ni,Fe) 9 S 8], or present as distinct mineral grains, for example, as braggite [(Pt,Pd)S].The minerals containing platinum-group elements are often attached to or occluded by grains of pentlandite, pyrrhotite [Fe 8 S 9] and chalcopyrite [CuFeS 2].

Platinum group elements have become imperative to many modern industrial applications (automobiles, jewelry, pharmaceuticals, electronics, fuel cells, etc.) but are mined in only a few places.

Platinum-group element concentrates are made into a matte that is relatively low in iron and sulfur, and enriched in platinum-group elements by smelting and converting. Smelting removes most gangue minerals as molten slag. Converting removes most iron and sulfur by oxidation with air and oxygen. In combination, these two steps upgrade the feed ...

platinum group, six metals, in order of increasing atomic weight, ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), and platinum (Pt). The elements all possess a silvery white colour—except osmium, which is bluish white. The chemical behaviour of these metals is paradoxical in that they are highly resistant to attack by most chemical reagents yet, employed as catalysts ...

Platinum-group minerals may be found in carbonaceous chondrites (e.g., Fig. 1a,b), where they occur as refractory metal nuggets (RMN) that have traditionally been considered to be amongst the earliest condensates in the Solar System (Palme 2008).

The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).

Jewelry that contains at least 950 parts per thousand of platinum group metals, with at least 500 parts per thousand of the total pure platinum, may be marked as platinum as long as the numbers of each metal are disclosed. For instance, "600 Pt. 350 Ir." or 600 Plat. 350 Irid." for 600 parts pure platinum and 350 parts iridium "550Pt. 350Pd. 50Ir."

The mine, which contains platinum group metals (PGMs) and chrome concentrates, began first production in November 2009. The Tharisa Mine produced 143,600 ounces (oz) of contained PGMs (5PGE +Au) and 1.3 million tons (Mt) of chrome concentrates including 323,100t of specialty-grade concentrates in 2017.

Transition Metal

The platinum group metals (PGMs) are a family of six structurally and chemically similar elements that are most valued for their wide range of industrial, medical, and electronic applications. These versatile metals play a significant role in many of the products we use every day.

Pt is Copper structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pt is bonded to twelve equivalent Pt atoms to form a mixture of edge, face, and corner-sharing PtPt12 cuboctahedra. All Pt–Pt bond lengths are 2.81 Å.

Mg2+(l) + 2e- Mg(s) Oxidation takes places at the anode: Cl-(l) ½ Cl 2 + e-7. The molar mass of Cl 2 (g) is (2 × 35.45) g mol-1 = 70.9 g mol-1 so 1000 kg corresponds to 1000 × 10 g 3 = 14100 mol. 70.9 g mol The half cell for chlorine is Cl 2 (g) + 2e- 2Cl-(aq) so the number of moles of electrons required is (2 × 14100) mol = 28200 mol.

The chromitites of the Bushveld Complex in South Africa contain vast resources of platinum-group elements (PGE); however, except for the economic upper group (UG)-2 chromitite seam, information on the distribution of the PGE in the ores and on the mineralogical nature, assemblages, and proportions of platinum-group minerals (PGM) is essentially missing.

This is a chart of the most common charges for atoms of the chemical elements. You can use this chart to predict whether or not an atom can bond with another atom.The charge on an atom is related to its valence electrons or oxidation state.An atom of an element is most stable when its outer electron shell is completely filled or half-filled.

This paper offers the first-ever study of a local chromitite stringer (~ 2 cm wide) enriched in platinum-group elements (PGE) from the Kevitsa Ni-Cu-PGE deposit. Chromite forming this chromitite is rich in Cr2O3 (29.06 ̶ 37.17 wt%) and FeO (FeOtotal = 45.88 ̶ 56.06 wt%) and low in MgO (0.04 ̶ 0.91 wt%). The chromitite host an unusual set of mineral inclusions including: (1) platinum-group ...
