I want ask about using zinc powder to percipitate gold from cyanide solution... My question is: how to deoxygenate (remove oxygen from ) gold bearing cyanide solution???
To deoxygenate a gold-bearing cyanide solution, you can employ several methods to remove the dissolved oxygen, which can include: Chemical Deoxygenation: The addition of a chemical reducing agent such as sodium metabisulfite can effectively deoxygenate the cyanide solution. The metabisulfite reacts with the dissolved oxygen and reduces it, thus deoxygenating the solution. Physical Deoxygenation: Utilizing techniques such as sparging with inert gases like nitrogen or argon can displace the dissolved oxygen from the solution, effectively deoxygenating it. Vacuum Deoxygenation: Application of a vacuum to the cyanide solution can help remove the dissolved oxygen, as the reduced pressure causes the oxygen to evolve from the solution. Use of Resin: Some specialized resins have been developed to selectively remove oxygen from solutions, which can be employed in deoxygenating gold-bearing cyanide solutions. It's important to carefully consider the specific requirements of the process and the potential impact on the gold-bearing cyanide solution when selecting the deoxygenation method. Always ensure to adhere to relevant safety and environmental guidelines when handling cyanide solutions and associated chemicals.
@@GDA-NEALWEI one last question mr. NEAL how to get red of cyanide wastes??? after percipitation with zinc powder I think there are zinc cyanide??? how to get red of it??
It is working in sulphide ore or higher copper ppm ores
The dosage of reagent may be relatively high. It is recommended to do more experiments to determine the optimal solution.

thanks for the clarification ....
on last question :
If I use the chemical deoxygenation by sodium metabisulfate ....
precipitate
try and see

one last question mr. NEAL
how to get red of cyanide wastes???
after percipitation with zinc powder
I think there are zinc cyanide???
how to get red of it??
Hi, very very good, what is lime ? Is calcium carbonate ?
