Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction. gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. in modern practice, concentrators use centrifugal force in
3. comminution and mill energy requirements comminution includes both crushing and grinding. initially, ore is reduced in size by crushing rock to a size that makes it manageable. crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. crushing is usually a dry process, and
Toward sustainability by bridging the gap in comminution - from finely crushed ore to stirred media milling abstract mining consumes approximately 7 of the worlds energy from which almost half goes for comminution. since the crushers are more energy efficient than mills, it is logic to push down-sizing in crushing stage s as far as possible.
Crushing some ores occur in nature as mixtures of discrete mineral particles, such as gold in gravel beds and streams and diamonds in mines. these mixtures require little or no crushing, since the valuables are recoverable using other techniques breaking up
