Gold centrifugal concentrator machine is a new type gravity concentration equipment for concentrating gold and other high density minerals. It is an efficient equipment for recovering free gold in all particle size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). From the beneficiation test, the concentration ratio can up to 500 times and recovery up to 99% for placer gold. For natural gold in gangue, when grinded particle sizes less than 0.074mm, the recovery can be up to 98% and up to 97% when less than 0.04mm.
1). Reliable High concentrating ratio(500 times) and high recovery(over 99%) 2). Total process automation, automatic ore concentrating & discharging 3). Environmentally friendly(requires no chemical additives or reagents) 4). Low water and electricity requirements 5). Low production costs, durable wear parts, minimal maintenances requirements 6). Compact design requiring less space, easy merged into the existing mining processing 7). Quick payback on investment, typically lass than half year
The materials are uniformly fed to the belt. When materials go through the permanent magnetic drum, the non-magnetic and low-magnetic particles will leave the belt surface because of the centrifugal force and gravitation. Meanwhile, strong-magnetic particles are absorbed to the belt by magnetic force and then fall into the magnetic trough when the belt leaving the magnetic pulley.
The following drawing shows the structure of the Gold Concentration Separator:
STLB Gold Concentration Separator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
