In cyanide extraction process of silver from argentite ore

Leaching is a process used for concentration or benefaction of ore. In this process, a powdered ore is treated with a suitable reagent, which can selectively dissolve the ore, but not the impurities. In cyanide extraction process of silver from argentite ore, the oxidising and reducing agents are respectively. O 2 and CO 2. O 2 and Zn dust

Explain the leaching process of silver and gold using

The addition of gold or silver to an alkaline sodium cyanide solution will cause the metals to react with the cyanide and dissolve them into the solution. The process is called cyanidation or leaching.

the extraction of silver by leaching with sodium cyanide

is used to extract precious metals like silver and gold by converting these metals or their ores into their soluble complexes by the process called as leaching. In this process, the finely powdered argentite or silver is treated with a dilute solution of sodium cyanide while a current of air is continuously passed. As a result, silver get

In the cyanide process for extraction of gold and silver

Silver and gold are extracted by the cyanide process (Mac Arthur Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.
