Carbon Regeneration System
The activated carbon regeneration system is used to increase the sorption activity of the carbon after the desorption process. A decrease in sorption activity is inevitable in the CIL/CIP process due to the presence of organic compounds in the process solutions. During the desorption process, some organic compounds do not pass into solution but remain on the surface of the coal. In addition, the pores of the carbon may be clogged mechanically by organic compounds. To reduce the consumption of fresh activated carbon, to reduce losses of precious metals in the CIL/CIP process, a carbon regeneration unit is used.
Working Principle
Its principle is based on the fact that under the influence of temperature, organics are burnt off from the carbon surface, thus opening the carbon surface for the sorption process. The furnace is designed in such a way that the material is not overheated, and the carbon is not burnt off unnecessarily. To increase the mechanical properties of the carbon after the regeneration process, we additionally recommend the installation of a carbon hardening tank.
