Abstract
A method is disclosed for the regeneration of spent carbon, which comprises the steps of acid washing the spent carbon, heating the washed carbon with microwaves 915 MHz or 2450 MHz to a temperature in the range of about 650° to 850°C in a nitrogen atmosphere, cooling the carbon to a temperature in the range of about 150° to 200°C, and thereafter quenching the hot carbon in air or water. The spent carbon to be regenerated may be that originating from a CIP (carbon-in-pulp) process for gold recovery or any process for the removal of environmentally toxic materials from solutions or gases.
