Palladium, iridium, and gold in the ores and host rocks of

Both palladium and platinum are distinctly lower than in average ore from the Merensky Reef. Palladium ranges from 5,000 ppb in high-grade massive ores with 20 weight percent nickel to 0.2 ppb in unmineralized ultramafic rocks; iridium varies from 1,000 to 3 ppb in the same rocks. Palladium and iridium correlate strongly with the nickel sulfide

Palladium and iridium in the evaluation of nickel gossans

Palladium and iridium show a strong positive correlation with nickel in Western Australian nickel sulfide deposits, and their inertness during weathering, combined with depletion of the more mobile components, usually results in retention or enhancement of the primary values in gossans and other oxidized derivatives.Precious-metal enrichment from background levels occurs in some lateritized

Palladium vs. Gold: Which Is Better? Goldco

Nov 15, 2019· Palladium belongs to what is known as the platinum group of metals: platinum, palladium, rhodium, ruthenium, iridium, and osmium. Palladium was only discovered in 1803, and it is a relatively rare silver-colored metal that is about 15% denser than silver. Palladium ore deposits are very rare, with only a handful of mines around the world

Bushveld Igneous Complex Wikipedia

The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs.
