Finishing Tables

Concentrate from 255lbs to 1/2ton per hour down to 400 mesh

Finishing Tables

The low-grade concentrates that ran through the GSI centrifuge now goes into our GSI Finishing Tables to produce a directly smeltable concentrate. These tables are the last step before smelting to bullion. Our tables have the capacity to concentrate up to 30kg (65lbs), 115kg (250lbs), and ½ ton per hour. They can recover fine gold down to 400 mesh and secure about 15% more than gold wheels at a faster rate.


GSI’s Finishing Tables have an easy-to-operate direct drive system with a geared motor that drives a crank connection to the table deck. This crank incorporates a spring connection system to absorb overrun. The GSI Finishing Table offers full variable speed control and requires a minimal 6 to 10 gallons per minute of water to run.
