摘要：

Pilot-scale tests indicate that effective concentration of fine gold from Colorado River sands can be achieved by flotation with the air-sparged hydrocyclone. The fine sands (55% - 400 mesh and 0. 01 opt) from gravity concentration were processed with a 5-cm air-sparged hydrocyclone (capacity 1. 0 t/h dry solids). Concentrate grades as high as 5. 0 opt were produced in a single stage at a recovery of 75%. The separation efficiency was better than that achieved in conventional batch flotation experiments.
