Particle Size Of Granular Activated Carbon Used In Mining

adsorption of gold by the activated carbon. Smaller particle size, for the same mass of activated carbon, enhances gold adsorption Yannopoulos, 1990. This is attributed to increase in surface area for adsorption and reduced mean pore length through which gold species travel within the activated carbon particles as particle size decreases.
