Native Elements and Minerals List ThoughtCo

Ancient man was familiar with several pure elements, mainly metals. Several of the noble metals, such as gold and platinum, exist free in nature. The gold group and platinum group, for example, are all elements that exist in the native state. The rare earth metals are among elements that do not exist in native

Platinum University of Denver

Native platinum is found here, as well as the very rare mineral Sperrylite, PtAs 2, the only platinum mineral. The platinum is accompanied by nickel and copper, as might be expected. Platinum also is often accompanied by iron, silver and gold, and is always found with the other members of its family.

Abundances of platinum group elements in native sulfur

Some porphyry Cu-Au deposits, which are enriched in Pd, are potentially an economic source of Pd. Magmatic volatile phases are thought to transport the platinum group elements (PGEs) from the porphyry source magma to the point of deposition. However, the compatibilities of the PGEs in magmatic volatile phases are poorly constrained. We report PGE and Re contents in native sulfur condensates

Occurrence of Metals | Introduction to Chemistry

Two groups of metals can also be found in nature: the gold group and the platinum group. The gold group consists of gold, copper, lead, aluminium, mercury, and silver. The platinum group consists of platinum, iridium, osmium, palladium, rhodium, and ruthenium. Native metal. Native gold partially embedded in quartz gangue.

Native metal Wikipedia

The platinum group consists of platinum, iridium, osmium, palladium, rhodium, and ruthenium. Amongst the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, and silver-mercury and gold-mercury amalgam. Only gold, silver, copper and the platinum metals occur in nature in large amounts.

Platinum group elements In native gold, By John B

Occurrences of platinum group elements were identified in 100 native gold samples (table 2) and in 234 heavy-mineral concentrates (table 3) from 213 localities (plate 1) from many of the larger placer mining districts of central and northern Alaska. Platinum, palladium, rhodium, ruthenium, osmium,

The Mineral Gallery Native Elements Class

The Elements (which include over one hundred known minerals) are a diverse class when taken as a whole. Most of this diversity, however, is due to the diversity of the Non-metals Subclass.. The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond. The greatest difference in the metals is color.

Rare Earth Metals From Asteroids | Astronomy Source

Platinum group metals. Platinum group metals do not occur naturally in the Earth’s crust, but are present due to earlier meteorite impacts. A meteorite is simply a piece of asteroid which has fallen to Earth, so the study of meteorites gives geologists a good idea of the most suitable types of asteroid to choose as candidates for mining.
