PDF ACTIVATED CARBON IN GOLD RECOVERY - Kemix

In the gold recovery industry, activated carbon from a number of precursors has been used. Due to the nature of the in-pulp process, the following characteristics are important: High affinity towards gold - kinetic activity and equilibrium loading. Hard, resistant to abrasion. Density, suited to mixing in pulp.
