Platinum was first mined commercially in South Africa.
But it is found in various amounts in gold ores, so that yellow gold in ancient Egypt contains platinum, and white gold in pre-Columbian Ecuador had significant platinum content. It was from South America that Antonio de Ulloa identified platinum as a separate metal, although alloys were studied by William Brownrigg and Charles Wood as early as 1741. A malleable form of the metal was prepared by Carl von Sickingen in 1772.
What else can I help you with?
Is platinum found in nature?
Yes, platinum is found in nature usually in the form of ore deposits along with other precious metals. These deposits are primarily located in South Africa, Russia, and North America. Platinum is also commonly found in some meteorites.
Is platinum usually found in a compound or a pure?
Platinum is typically found in nature as a pure metal, rather than in a compound form. It is often mixed with other metals like palladium, rhodium, and iridium in the form of an ore called "platinum group metals."
Where is rhodium found and in what compound?
Rhodium is primarily found in platinum group metal ores, such as pentlandite and pyroxenite. It is commonly mined in South Africa, Russia, and Canada. In nature, rhodium is often found alloyed with other platinum group metals like platinum and palladium.
What is the rarest metal in the earth's crust?
The rarest metal in the Earth's crust is believed to be rhodium. It is a platinum group metal that is scarce in nature and often found in association with other platinum group metals. Rhodium is primarily sourced as a byproduct of platinum and palladium mining.
Which metals occurs in a free state?
Only a few metals are found in the free state, generally metals react to form for example oxides, sulfides which then may further react. Some found free are gold silver copper and platinum. All of these are relatively unreactive
Is the element platinum found free or is it chemically combined in nature?
Platinum usually exists uncombined in nature or alloyed with iridium.
Is platinum found in nature?
Yes, platinum is found in nature usually in the form of ore deposits along with other precious metals. These deposits are primarily located in South Africa, Russia, and North America. Platinum is also commonly found in some meteorites.
Is the type of magnetic mineral found in nature called platinum true or false?
No type of magnetic mineral found in nature is properly called "platinum" by a chemist, because platinum is a chemical element and is not magnetic! The most common magnetic mineral found in nature is called "magnetite". It contains both iron (II) and iron (III) oxides in nearly constant proportions.
Is platinum usually found in a compound or a pure?
Platinum is typically found in nature as a pure metal, rather than in a compound form. It is often mixed with other metals like palladium, rhodium, and iridium in the form of an ore called "platinum group metals."
Is platinum an element mixture or compound?
Platinum is an element, not a mixture or compound. It is a rare and valuable metal that is found in its pure form in nature and consists of only platinum atoms.
Is technetium found in pure form?
No. Almost all technetium is man made. In nature it is found only in trace amounts mixed in uranium or platinum ores.
What 3 expensive metals can be found in native form in nature?
In order of greatest value to least: Rhodium, Rhenium, Platinum, Gold, Electrum, Silver
What form is platinum?
Platinum exist in the nature as pure platinum, in alloys or as compounds (sulfides, arsenides).
Where is rhodium found and in what compound?
Rhodium is primarily found in platinum group metal ores, such as pentlandite and pyroxenite. It is commonly mined in South Africa, Russia, and Canada. In nature, rhodium is often found alloyed with other platinum group metals like platinum and palladium.
Is platinum a type of magnetic mineral found in nature?
yes look in a sciece book in the periodic chapter and you'll see hopefully
What two unreactive metals are found native?
Gold and platinum are two unreactive metals that are found in their native state, meaning they are found in nature in their pure form without the need for further processing.
What is original form?
Platinum exist in the nature as pure platinum, in alloys or as compounds (sulfides, arsenides).
