The Eriez Flotation offers a complete line of column and hybrid flotation technologies engineered for coal and minerals processing industries.

The CoalPro® benefits coal producers with low capital and operating cost and ease of operation. The CoalPro with SlamJet® sparging technology has no large aeration pumps, no large feed or recirculation pumps and no downcomers with complex piping. This unit has patented SlamJet® technology with automatic fail closure on loss of air. The CoalPro treats a variety of classified (150 x 45 micron) and unclassified (150 x 0 micron) raw coals to produce low ash products.

For a more aggressive approach, option the CoalPro with CavTube® sparging technology.

Another product initially commercialized for coal applications is Eriez' StackCell®, a two stage high efficiency mechanical cell.
