Applications

PARTICLE CONCENTRATION

Hindered-bed separators can concentrate particles based on size, density and shape. With feed stocks having a relatively tight size distribution, separations based on density and shape can be successfully achieved.

SIZING/CLASSIFICATION

Minerals can be separated based on particle diameter when treating feed stocks having a consistent density but a wide size distribution.

WASHING

In the CrossFlow separator, particles settle against a countercurrent flow of fluidization water. As a result, this quiescent, plug-flow system provides an excellent method for rinsing, cleaning and washing material.

SPLIT-FEED COARSE FLOTATION CIRCUITS

Eriez developed the HydroFloat Separator specifically to treat coarse material. With this new separator, process engineers can now maximize efficiency by designing split-feed flotation circuits where coarse material is treated separately from the fines.

SCAVENGING

The development of the HydroFloat was based on applying flotation fundamentals to teeter-bed separation. The presence of the fluidized bed increases collision rates beyond that which can be obtained in open flotation cells. As a result, the HydroFloat excels as a scavenging device.

LEACHING

In the CIL/CIP process for most gold ores, metallic gold must be cyanidized during the process. Millions of micro bubbles produced by spargers ensure rapid transfer of oxygen to the pulp.

COLUMN CELLS AS ROUGHERS

Columns are often discounted as roughers because of the beliefs that a) mechanical cells will provide a higher level of recovery, and, b) higher recovery provides more revenue than higher grades. For simple ores, this is may be true. For more complex ores containing impurities which translate into additional treatment and refining charges, or for mines located in very remote regions, the benefit of being able to produce high grade concentrates even at the expense of a slight reduction in recovery, may make economic sense.
