    Jun 01, 20160183;32;One of the limitations of the cyanidation process is the uneconomic gold recovery from particular ores, termed refractory. La Brooy et al. (1994) suggests that there are three ways the refractory ore may interfere with the cyanidation process I. Locking of gold in a mineral matrix, preventing leach reagents reaching the gold.
