hi
we have small mine in Egypt , we are using vat leaching followed by active carbon , at the moment we don't have atomic adsorption so my question is about assaying and get the gold concentration in cyanide solution ,on the active carbon and in tail solution
for cyanide we know the silver nitrate method , what about assaying carbon and tail solution
and if someone could help me with the smelting of the active carbon and ashing it
 
Hello,

I like to help you with the problem. What i can suggest is what we are doing here in our country. We first get 15kgs of ore and agitate it for 24hrs. with a certain cyanide concentration depend of the ore 1% to 0.5% using silver nitrate to determine it.
Here we can found out the optimum extraction of Au(gold) in cyanidation.

About ashing the preg-carbon, we pour a diesel or kerosin and burn it in a controlled air ventilation until it turn to ash.

let us help each other!!!
I am also currently studying the best way to extract gold in a copper rich gold ore.
