extraction of copper gold and silver

  • copper extraction and purification

    Extracting copper from other ores. Copper can be extracted from non sulphide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

  • Silver amp; Gold Cyanide Leaching of Copper Ore

    Effect of Copper on Leaching of Pure Gold. Metallurgists have long investigated the effect of copper in cyanide solutions on the leaching of pure gold and on the extraction of gold from ores. In their tests on pure gold, they prepared cyanide solutions containing copper by dissolving relatively pure cuprous cyanide, CuCN, in sodium cyanide.

  • Eliminating Copper from Gold Ore

    Eliminating Copper from Gold Ore. The use of cyanides in the extraction of gold and silver is well known. Such extractions employ concentrations of cyanide in the range of 0.02 0.25% sodium cyanide equivalent in leaching cycles of 24 48 hr and frequently longer. Copper minerals, even though minor components of precious metal ores,

  • The Extraction of Silver Chemistry LibreTexts

    Extraction. 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 \(Na [Ag(CN) 2]\).
