Produce copper directly at the mine. Rapid Oxidative Leach (ROL) is another of our innovative about to rock your world. This mechano-chemical process can leach 97-99% copper directly on site, from concentrates as low as 5% copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the

Thus, high-efficiency separation of scheelite from fluorite will be achieved by controlling the pH range of the flotation pulp. Although the complex also has a certain collecting ability for calcite, the calcite was easily depressed by a small amount of sodium silicate ( Fig. S13 (a)), indicating that the adsorption of the complex on the
