The conventional processes for recovery of silver from cyanide leach solutions are the carbon adsorption, the MerrillCrowe zinc dust cementation, the Ion Exchange, and Solvent Extraction processes; among other available options for recovery of precious metals from cyanide solutions, Electrocoagulation (EC) is a very promising electrochemical process that does not require high concentrations of silver in .
To extract gold from ore, mining companies typically use the sodium cyanide process, in which the gold is converted into a watersoluble coordination complex and activated carbon is used to .

Gold is generally found in two types of deposits: lode (vein) or placer deposits; the mining technique used to extract the gold depends upon the type of deposit. Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carboninpulp.
extracting gold from water through electrolysis. As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any sizereduction requirements, including quarry, aggregate, grinding production and complete plant. We also supply individual crushers and mills as well as spare parts of them.
Extracting copper from other ores. Copper can be extracted from nonsulphide 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.

Oct 12, 2007· Answers. Best Answer: Carbon anodes would work. For the cathode, either gold or platinum would improve the purity of your extract. (Why add another metal?). KCN ?????? If you have to ask this question, stay the heck away from cyanides. They can produce a highly poisonous gas at the anode, and KCN is toxic enough...
In the all sliming zinc powder replacement process, the concentration of CNFREE ECO gold leaching agent and oxygen are closely related to the gold recovery rate. The metal zinc is added to the pregnant solution after purification and deoxidation, after the displacement reaction, the gold in the pregnant solution is replaced by a metal state to precipitate, and the zinc is dissolved in the alkaline leaching .
There are four main processes of gold extraction: Mechanical processes for preparing and washing the ore. Preparation of the ores, with simultaneous or subsequent amalgamation. Chemical extractionprocesses. Smelting of certain ores.
This process is called Gold cyanidation, this process is also known as cyanide process, and the MacArthurForrest process. This process is a hydrometallurgical technique for extracting gold from low grade ore in the way that it converts the gold to a watersoluble coordination complex.
Extracting Gold from Scraps. This process raises the pH levels of the acid, thereby eliminating the nitric acid. Heat a quart of water to boiling and add the sodium bisulphite to the boiling water in the ratio of 1 ounce of sodium bisulphate for every ounce of metal being refined. Pour this mixture slowly into the acid and wait for a reaction.
