The method of extraction of silver by cyano

Cyanide process is used for the extraction of Ag which is also called as MacArthur - Forest process.Reactions involved in the extraction of silver are as follows: Ag2S + 4NaCN→ 2Na[Ag(CN)2] + Na2S (reversible reaction) 2Na[Ag(CN)2] + Zn→ Na2[Zn(CN)4] + 2Ag Hence, option B

Types of Extraction | S-cool, the revision website

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to
