critical as it will prevent overgrinding of gold and capture any coarse particles before they report to the flotation circuit. Refractory Gold Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are:

GRINDING COPPER ORE As it is shown in this study the ¾" or 1″ crushed ore is fed to a rod mill operating in open circuit and discharging a product approximately minus 14-mesh. The discharge from this primary rod mill is equally distributed to two ball mills which are in closed circuit with SRL Rubber Lined Pumps and two or more cyclone classifiers.
