Application of carbon regeneration kiln. The regeneration kiln heats the used activated carbon to a high temperature of 700-750 ℃ to decompose the organic impurities adsorbed on the surface of the carbon into CO2 and other substances to volatilize, and activates the carbon with high-temperature water vapor, so that the activated carbon adsorption …
In most CIP circuits the temperature in the carbon regeneration kiln is maintained above 500 °C and for the studied circuit, it was even higher (≈ 650 °C). It is anticipated that the non-eluted gold was thermally converted into metallic gold in the carbon regeneration kiln.
The high temperature condition in the carbon regeneration kiln (> 500 °C) caused thermal reduction of the non-eluted auro–cyanide complexes to metallic gold, …
