I want to recover gold from gold cyanide solution. This solution contains hydrogen peroxide also. I have tried metal displacement method. It does not give complete gold recovery. Please suggest me some chemical method through which I can recover all the gold from this solution. Thanks!
Gold recovery from cyanide solution by bacterial consortium was studied by Aitimbetov et al. (2005).The main mechanism underlying this process was .
Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. These processes are DANGEROUS and put the user at t...
Ion exchange resins were investigated for the effective recovery of platinum, palladium, and gold from a pregnant cyanide heap leach solution. Screening results indicated that strongbase anion exchange resins proved to be most effective in the recovery of these metal cyanides.
In the gold beneficiation process, activated carbon is a vital tool, used to separate gold that has been dissolved in a cyanide solution, so that it can be recovered. The Gold Cyanidation Process. The gold cyanidation process is a series of steps that vary depending on the .

We have high grade deposit and traditional mining. W e have leached gold into cyanide solution but due to cost of electrowinning cell and power unavailibility in the desert we get stuck, any idea how to recover that gold from the solution without electrowinning or ship electrowinning procedure ?
Traditional methods for the recovery of gold from electronic scrap by hydrometallurgy were cyanidation followed by adsorption on activated carbon or cementation onto zinc dust and by electrowinning. In our studies, a static batch electrochemical reactor operating in an electrogenerative mode was used in gold recovery from cyanide solutions.
