2013-11-27 Granite porphyry intrudes the dolomite, and no basic igneous intrusive rocks are known in this region. The ore is oxidized and contains a bismuth-bearing variety of plumbojarosite. All metals at the Boss Mine are found in minute division. The gold is rough, black and spongy, the palladium-platinum appears as microscopic black grains.

PLATINUM AND PALLADIUM IN SOME

2010-8-17  Preliminary Bureau of Mines studies of mafic igneous rocks collected from the Rabbit Creek area, northwestern Alaska, indicated concentrations of platinum (412 to 1,406 ppb) and palladium (343 to 892 ppb) in five of eight samples analyzed. The samples represent boulders and cobbles of mafic/ultramafic rocks from this locality.

Palladium,. Add holdback carriers for Na, K, Cu, Co, Zn, and Mn to the slightly acid aqueous solution containing the Pd; heat nearly to boiling, and precipitate the Pd by the addition of S ml of 1 per cent solution of dimethylglyoxime in methanoi. Allow to stand a few minutes, centrifuge, and wash the palladium glyoxime twice with water.

What About Palladium? January 2020 by Chris Ralph. Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.

2020-5-29  High-grade gold, palladium, and platinum values ranging to 16.18 g/t 3E (13.80 g/t Au, 1.10 g/t Pd, and 1.28 g/t Pt) were returned in rock samples taken by Group Ten in 2019 at the Pine target, with a total of 13 samples returning from 2 to 30 g/t

Hydrothermal Solubility of Palladium

2019-11-25  The solubilities of palladium in the solutions at a constant pH of 6.5 increased with increasing NaCl concentrations at all test temperatures, particularly at lower temperatures. In solutions with high NaCl concentration (1 molal and 3 molal), the solubility of palladium decreased dramatically from 300 to 700C.

2020-8-11  Platinum and palladium are precious metals generally found in ultramafic rocks. The source of platinum and palladium deposits is ultramafic rocks which have enough sulfur to form a sulfide mineral while the magma is still liquid. This sulfide mineral (usually pentlandite, pyrite, chalcopyrite or pyrrhotite) gains platinum by mixing with the

Poisson's ratio values for rocks ScienceDirect

2007-1-1  For isotropic rocks, therefore, the value of Poisson's ratio is practically between 0 and 0.5. In fact, the range bounded by the values of 0.05 and 0.45 covers most rocks. Also, in some rock engineering applications with limited field data, a value between 0.2 and 0.3 is a common estimate for Poisson's ratio. 4.1.

2021-6-10  Platinum is considered a Noble Metal. It is an extremely stable element used in many areas of industry. The annual supply is, on average, 130 tons. It is the rarest of the precious metals, and its scarcity makes it an ideal commodity for investors to purchase. Volcanic heat produced well below the Earth’s crust acts as a blast furnace helping

The Bushveld Large Igneous Province

2011-1-28  Until the 1990’s, it was envisaged that the magmatic rocks of the Bushveld Large Igneous Province evolved over a long period of time, possibly exceeding 100 Ma. However, research in the last decade has shown that the Rooiberg Group volcanics, the Rashoop Granophyre Suite, the intrusive Layered Suite and Granite Suite were synchronous (Table 2).
