The AVI's illustrate the pickup
cone (centrifugal concentrator) used in the gold-mining industry for
extraction of the gold from the milled rock. The
construction is very compact (mass of the transportable devise is about
30kg) and automatic. In the non-interuptable regime the production
rate of the device is 3-5 tons per hour. The quantity of the
extracted gold reaches 99% for the coarse particles and 50% for fine.
