Extracting from low grade ores - FL

Reduce processing cost for gold and copper extraction Many existing gold refractory operations have low-grade stockpiles that are waiting to be processed at the end of the mine life. By adding Rapid Oxidative Leach® (ROL®) pre-treatment to an existing operation, it can become viable to process these low-grade stockpiles earlier, rather than processing them at the end of the mine life.
