I need to know how to Remove Trash from Recovered Gold Rich Carbon. Kindly share your ideas on how to remove excess trash specifically wood from recovered carbon in CIL circuit prior to gold elution.

Have you considered trash screens with an opening large enough for the carbon but smaller than the wood? These are often trommels. Another concept that I have seen work is the use of a settling tank, with the wood floating off the top.

Deister Sieve Bend Screens are perfect for this kind of application. They manufacture ceramic or metal lined feed boxes for improved wear rates and have the advantage of a reversible screen to allow for longer periods of operation and longer screen life.

If the process is dry then depending on the particle size you can consider using Zig Zag air classification, we have installed this system in one of our reclamation lines and it work perfectly.

Use of vibrating screens prior to the CIL with 500 to 600 micron apertures works quite well and keep the preg robbing wood out of the leach tanks.
I will be in Ghana next week visiting with several gold companies. I might be able to visit you as well depending on my schedule.
