Crystallex's Las Cristinas Gold Project - Crystallex International .

Jan 18, 2004 . An initial series of CIL tests investigated the effects of grind (P80 of 110, 75, and 50 micrometres) and time (12, 24, 48 h) on leaching of the SAPO-CSB blend with a cyanide strength of 0.5 g/L. This work showed that a grind of 75 micrometres and CIL time of 36 h was optimum and most additional leach tests.
