Platinum-group minerals and gold in Arsenic-rich ore at

Platinum-group minerals (PGM) and native gold are reported in association with gersdorffite ± nickeline from the Thompson mine, Thompson Nickel Belt, Manitoba, Canada. Four PGM-gold-bearing ore types are distinguished on the basis of mineral assemblages and host rocks: I. Irarsite in massive Ni sulphide ore hosted by metapelite; II. Gold, sudburyite, testibiopalladite-antimonian michenerite

2021-10-31 Because chondrites are rich in metal and the metal is rich in nickel, all chondrites have bulk (whole-rock) concentrations of nickel of 1.0-1.8% (i.e., 10,000-18,000 ppm). That is 100-1000 times greater than practically any terrestrial (Earth) rock. An Earth rock with as much as 1.0-1.8% Ni would be a nickel ore.

Radomskaya materials (cRM) nickel concentrate Nc-1 No.1702-86 and concentration tailings XO-1 cRM No.1703-86 (Radomskii, Radomskaya, 2017). We analyzed averaged quartered samples of 14 ore columns (34 samples) and 18 samples of host and developed rock. The analysis of noble metal

Determination of the Platinum‐Group Elements and Gold

The platinum‐group elements (PGE) and gold have been determined in twenty international rock reference materials by inductively coupled plasma‐mass spectrometry (ICP‐MS) after pre‐concentration by a nickel sulfide fire assay. It was possible to achieve determination limits for a 50 g sample that ranged from 1 pg g ‐1 (Rh) to 23 pg g

ANAX DEFINES EXTENSIVE PLATINUM, NICKEL-COBALT

2021-7-27 separated in the lab and analysed for an extensive suite of elements including nickel, cobalt and platinum, as well as gold and ‘indicator’ elements. This method bypasses the “nugget” effect common in conventional soil and stream sediment analysis and is being used by gold explorers across the region, contributing to a region-wide study.

Platinum-Nickel-Chromium Deposits ScienceDirect

The Platinum Group of Elements (platinum, palladium, iridium, osmium, ruthenium, and rhodium) are rare, extremely scanty, noble, and precious transition metals that naturally coexist with nickel, chromium, copper, cobalt, gold, and silver. The metals occur by a unique mineralizing process, are spread closely in the Periodic Table, and are

Nickel sulphide fire assay for the collection of the

Fire assay is a classical method for the separation of the platinum group elements and gold (PGE + Au). In nickel sulphide fire assay nickel and sulphur are used for the preconcentration of PGE + Au. In the past the authors have successfully reduced the weight of the collectors used without affecting the recovery of the elements from silicate material and eliminated the reagent blank problem

MAGMATIC SULFIDE DEPOSITS (MODELS 1, 2b, 5a, 5b,

2004-4-5 Primary abundance variations of nickel, copper, and platinum group elements in magmatic-sulfide ore are controlled by the composition of the silicate magma and the mass ratio of silicate to sulfide liquid (Naldrett, 1989). In addition to sulfur, iron, nickel, copper, cobalt, and the platinum group elements (platinum, palladium, rhodium, ruthenium,

Comparison of Recoveries by Lead Fire Assay and Nickel

We compared the recovery of gold, palladium and platinum by two fire assaying procedures, using nickel sulfide and lead as collectors. The presence of appreciable amounts of sulfide minerals in the sample caused interferences in both procedures. An in-house reference sample, a reference sample of high-grade sulfide ore and samples of high sulfide content from the Recsk porphyry copper ore in

2019-9-27 Deposits in which the ore minerals have crystallized directly from a magma. Generally found in mafic or ultramafic igneous rocks, typically layered complexes. Three major deposit types: i) Nickel-Copper Deposits ii) Chromite Deposits iii) Platinum Group Elements Deposits Minor amounts of Cr and PGE are also recovered from eluvial or

Comparison of Recoveries by Lead Fire Assay and Nickel

It was found that for the sulfide ore samples, the recoveries of Au and Pd are sometimes lower by nickel sulfide fire assay than by lead fire assay. Recovery of Re by nickel sulfide fire assay was found to be low: the average recovery of five repeated analyses of the reference sample NIST SRM 330 was 9% with a relative standard deviation of 48%.
