Extraction of low reactivity silver platinum and gold
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. Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals 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.

Kappes, Cassiday & Associates specializes in providing technology and management services for the processing of gold and silver ores. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in free-state; such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores. 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.

Extraction of Low Reactivity Metals 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 chemical reducing . Collect information about extraction of metals of low reactivity silver, platinum and gold and prepare a report. Zn + 2 Na [Ag(CN)2] → Na2 [Zn(CN)4] + 2 Ag. 6) The spongy silver is fused with potassium nitrate to obtain pure silver. Extraction of Gold: Gold is extracted from the ore called as Electrum by treating the ore with weak cynaide solution. Zinc is added and gold separates from the ore. Extraction of platinum: Extraction of platinum involves froth flotation and smelting 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.
