WALNUT REYCLING PROCESS
Walnut shell processing is the process of recovering gold from the dust by burning the walnut shells used in the polishing drum after their useful life is over. After the finished walnut shells are placed on the square tray, they should be placed in the oven at 800 degrees and taken out of the oven slowly and with intermittent mixing and fed back. In the second and third hours, depending on the amount of material, burning may decrease or end. Since walnut shells are difficult to burn, this process may take 4-5 hours. The powder of the walnut shells, which are ensured to be completely burned, is sifted through a fine sieve and taken into the aqua regia process. Large and bulky pieces are baked again and the process is repeated and the process is terminated when all of them are finished.
