Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ore in a very specific way.
Pure platinum is a lustrous, ductile, and malleable, silverwhite metal. Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. The metal has excellent resistance to corrosion, is stable at .
Silver, gold, and platinum are metals with the least reactivity. They are found in nature. The metals with high reactive series in the above table also indicates that reverse reaction is a bit tough process. Reactions are mostly Exothermic in case of highly reactive metals. The reaction takes place fast in highly reactive metals.
The chief are of silver is argentite and silver is extracted by hydrometallurgy process. The silver are is dissolved in cyanide solution to form soluble argento cyanide complex from which metal is obtained by reduction with more electropositive. The different steps involved in extraction of silver are: a. Ore – .
These revision notes on the methods of extracting metals and relating the extraction method to the chemical reactivity of the metal should prove useful for the new AQA, Edexcel and OCR GCSE (9–1) chemistry science courses. Metal extraction index. 1. Introduction to Metal Extraction (this page) 2. Extraction of Iron and Steel Making. 3.
Mar 03, 2009· Extraction of metals Only some unreactive metals such as silver, gold and platinum can occur freely in nature. Most metals react with other elements to form o. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
Knowing future precious metals prices can be difficult to project in stable times. Perhaps more so now, because the old world order is changing. But we believe gold and silver will do well in 2019. Oil has had a rapid and significant drop, that thus far has not been halted by production cuts.

Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other nonmetals present in nature. Such metals may remain in elemental or native (free) state in nature. Such metals are called "noble metals" as they show the least chemical reactivity. For example gold, silver, mercury and platinum occur in free state.
Metals found at the bottom of reactivity series are least reactive and they are often found in nature in freestate; such as gold, silver, copper, etc. Copper and silver are also found in .
Extraction of Platinum. 1) Platinum is rarely found on its own, but in combination with other base precious metals. 2) The extraction process of platinum is quite complex, which includes milling the ore and smelting it at high temperatures. This removes base metals notably the concentrate PGM (platinum Group Metals) – gold, platinum ...
Native metal. Only gold, silver, copper and the platinum metals occur in nature in larger . the less reactive metals such as gold and platinum are found as native metals. . since the process of extracting metals from their ores, smelting, is thought to .. of the ironnickel alloys: taenite (high nickel content) and kamacite (low nickel content).

Editor''s Note: The article was updated to a reflect weaker prices in delayed reaction to the latest CPI data. Gold prices are down on the day but holding on to gains above 1,500 an ounce as inflation pressures were weaker than expected last montThursday, the Labor Department said its Consumer Price Index was unchanged in September, after a % rise in August.
Extraction of Silver by cyanide process and its uses. Silver also occurs both in combined state as well as in free state. The important ores of silver are: Argentite (Ag 2 S), Copper silver glance, Horn silver, Ruby silver. The silver ores are found along with gold ores in some parts of India.
Dan Kappes is the President of Kappes, Cassiday Associates, a 50person firm based in Reno, Nevada, with offices in Perth, Western Australia and Lima, Peru. Kappes, Cassiday Associates specializes in providing technology and management services for the processing of gold and silver ores.
Silver plays a certain role in mythology and has found various usage as a metaphor and in folklore. The Greek poet Hesiod''s Works and Days (lines 109–201) lists different ages of man named after metals like gold, silver, bronze and iron to account for successive ages of humanity.
In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores
2 days ago· So far, the dollar price of gold has risen by 42%, while the silver price has risen just 26%. This is consistent with an early phase of a continuing bull market for precious metals and suggests that an acceleration in silver''s rising price will occur on gold''s next bullish move. Platinum
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
Metals with low reactivity can be found as elements silver, gold and platinum. Metals up to and including zinc are extracted by heating with carbon (zinc, iron, tin, lead and copper) . Metals above zinc in the reactivity series (high reactivity) are extracted from their compounds by electrolysis of the molten compound (melted compound).
Jan 17, 2016· Only gold, silver, copper and the platinum metals occur in nature in larger . the less reactive metals such as gold and platinum are found as native metals. . since the process of extracting metals from their ores, smelting, is thought to .. of the ironnickel alloys: taenite (high nickel content) and kamacite (low nickel content).
Gold, Silver, Platinum, Palladium and Titanium are precious metals, meaning they are rare metallic chemical elements of high economic value, shiny, hard, strong with high melting points. They form alloys (mixtures) with other metals and this makes them ideal for jewellery.
Precious metals can be found in ore deposits along with sulfur, and are known as sulfides. Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated ...
