Choose A Falcon Gravity Concentrator for Fine Gold Recovery
This is because the falcon is operated at higher rotation speeds than the Knelson™, without fluidizing water. Because of large rotation velocities, the Falcon concentrator lowers both the size of the optimum and minimum recovery below 25μm. In particular, the batch Falcon is effective in the fine range (less than 37μm for gold).
