This work explores the use of activated carbon (AC) synthesized from sugarcane bagasse (SB) to adsorb volatile carboxylic acids (VCA). Activation was performed by impregnation of SB with 20 and 35 % v/v H3PO4 (resulting P20 and P35 respectively) and by impregnation with 30 and 40 % v/v ZnCl2 (resulting Zn30 and Zn40 respectively). Since a low adsorption of VCA …

Carbon Stripping – Denver Mineral Engineers

Activated carbon has long been known to exhibit a strong affinity for the extraction of gold from cyanide solutions. It was not, however, until methods for chemically desorbing gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. These procedures allowed the carbon to be recycled for ...
