In cyanide extraction process of silver from argentite ore

The extraction of silver involves in cyanide process are:(i) Ag2S + 2CN- + O2 → 2[Ag(CN)2]- + SO2(ii) [Ag(CN)2]- + Zn → [Zn(CN)4]2- + AgThus, in equation (i) O2 act as oxidising agent (Oxidise sulphide to SO2) and in (ii) Zn act as reducing agent (reduce Ag+ to Ag). In this process, a powdered ore is treated with a suitable reagent

Process Of Extracting Silver From Ore

Silver is extracted from the ore-argentite (\(Ag_2S\)). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide \(Na [Ag(CN)_2]\). Silver Ore The Mining Processes that Transform

Cyanide process is used for the extraction of MyAptitude

The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The argentite ore dissolves in sodium cyanide forming sodium argento cyanide. Ag 2 S + 2NaCN → Na[Ag(CN) 2 ] + Na 2 S

Name the important ore of silver. Write all the steps and

The important ore of silver are Argentite (A g 2 S) and Horn Silver (A g C l). Extraction of Silver from ore by cyanide process: In this process the finely powered ore is concentrated by froth flotation process and then treated with dilute N a C N and a current of air is passed into the solution so that A g present in the ore is converted into

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.

The extraction of silver involves in cyanide process are: (i) 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

Cyanide process metallurgy Britannica

Cyanide process, also called Macarthur-forrest Process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest. The method includes three steps: contacting the finely ground ore with the cyanide
