Oct 27, 2020 These microcracks create ‘canals’ to the gold ore particles trapped inside the parent rock, allowing the leach solution to access the gold and do its job. The more microcracks and fines produced, the more gold can be recovered. Micro-cracking also increases the leach kinetics which speeds up the gold recovery rate versus conventional crushers.
