A microbubble flotation machine can replace the one coarse, two sweep, and three fine processes, with obvious indicator advantages.
Comparative Test of Microbubble Flotation Machine and Field Flotation Column in a Gold Mine in Henan Province
The degree of oxidation of the ore varies greatly, with strong alteration and severe mudding of the grinding products.
The on-site use of flotation columns to enhance the recovery of fine gold particles has not achieved ideal results, and the loss of Au metal in tailings is mainly distributed in the -0.020mm particle size.
The precision micro bubble flotation machine increases the enrichment ratio by 5 compared to the on-site flotation column, and the recovery rate is nearly doubled. A single micro bubble flotation machine can achieve a concentration ratio of over 20, a recovery rate of 50%, and directly produce concentrate products.
