Carbon loaded with gold is sent to a washing vessel where a hydrochloric acid solution is used to dissolve various impurities. These impurities, commonly calcium, copper, lead, nickel and others, block the active sites on the carbon which are available to attract a chelated cyanide/gold molecule. The gold stays

Crushing Circuit - an overview | ScienceDirect Topics

The screen is marginally coarser than those in the leach circuit to ensure that carbon particles are effectively retained in each leach tank. Loaded carbon recovered in the leach circuit is eluted for a pre-determined period in a series of columns, with hot 1% caustic solution containing 0.1% NaCN at atmospheric pressure.

place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher. Usually, some form of separation follows size reduction. The most common is simple screening, in which the screen openings are selected to pass the desired size range and retain material that is too ...
