The main technical conditions for the adsorption of gold in the noble liquid by activated carbon adsorption heap
The main technical conditions for the adsorption of gold from the activated carbon adsorption heap are: For yarn dyeing section, we can provide all line of machine, such as pakcgae and cheese yarn dyeing machine, hydro, dryer and winding machine Package dyeing machine, fiber dyeing machine, hank dyeing machine, hydro extractor, steam dryer, RF dryer JIEPAI MACHINERY , https://www.jyjiepai.com
The noble liquid that enters the carbon adsorption should contain as little heavy metal ions and other harmful impurities as possible. The gold concentration of the solution should generally be above 1g/m3 to ensure the gold content of the gold with higher gold content. At the end of the heap leaching and the washing stage, the gold concentration of the gold solution to be adsorbed can be appropriately reduced according to the actual situation.
The amount of activated carbon fed to the adsorption system should be determined by the amount and gold content of the gold-containing solution being treated. The particle size of activated carbon should be 12 to 30 mesh. Activated carbon should have sufficient strength.
In order for the activated carbon to form a fluidized bed in the adsorption column, it is necessary to ensure that the solution entering the column (tower, tank) has a sufficient flow rate, and should generally be controlled at 450 to 600 liters/meter 2 minutes.
