Information about extraction of metals of low reactivity

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

Aug 01, 2017· Metals like copper, mercury, silver and gold are less reactive. Metals at the bottom of the reactivity series can be obtained by heating their compounds. For example, when cinnabar (HgS) is heated in a furnace, it is reduced to metallic mercury. Metals in the middle of the series like zinc, iron, nickel, tin, lead, etc., are reduced by a

Reactivity Series of Metals Get the Chart, Significance

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.

Reactivity series Wikipedia

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, single displacement reactions and the extraction of metals from their ores
