Sparging systems for coal processing

Published by

Eriez Flotation Division (EFD) provides spargers for a range of applications, including fine and coarse mineral flotation, liquid/liquid separation, oxygen service and air/water mixing duties. The sparging systems available from EFD are the CPT SlamJet® and the CPT CavTube™ designed for the coal and minerals processing industries.

Flotation and leaching applications depend on the generation of bubbles that are correctly sized and that are evenly dispersed across the separators. The key is to generate the optimal number of bubbles of the correct size at the right rate. Both the SlamJet and CavTube spargers are designed, engineered and optimised for each coal and mineral processing application.

The CPT SlamJet sparger can be removed without draining the separator or shutting down the system. This unit automatically shuts off in the event of a supply gas failure to prevent process fluid from backing up into the gas line. A single, large-bore orifice virtually eliminates plugging or fouling. The simple design and durable construction of SlamJet spargers ensure a long operating life.

The CPT CavTube sparger uses hydrodynamic cavitation to produce fine bubbles that enhance separation for improved product grade and recovery. CavTube sparging systems are used in a variety of column flotation applications, including iron ore, phosphate, fluorite, niobium, feldspar, mica, coal and molybdenum.
