The macropores allow for the rapid movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.

2021-2-18 Although activated carbon has been used in gold-silver recovery from cyanide solutions for several decades, the mechanism of gold adsorption on activated carbon is still not fully understood. One theory is that the gold is adsorbed as the gold cyanide complex Au(CN)2- and that this adsorption takes place by ion exchange.
