The Application of the Stackcell Technology for Fine Coal

Unlike many metalliferous and industrial mineral applications, fine coal flotation circuits are typically characterized by feed streams containing a low solids content (5%, by weight) where up to 85% of the feed can report to the product launder. With input from major engineering houses and end-users, the Eriez Flotation Division (EFD) developed the StackCell technology with the goal of

Water-Only Cyclone Spiral Circuit Unloads feed distribution to spirals. Recent emphasis in metallurgical coal production is lowering the separation density of the fine circuit. Water-only cyclones provide a low density cut but tend to lose coal. Spirals tend to ensure coal recovery but have a high density cut. Combining the two units

Control Strategies for Coal Flotation Circuits AusIMM

The incentive to control coal flotation circuits arises because of disturbances, from plant operating practices and variations in feed coal characteristics, which result in large amounts of fine coal being lost in circuit tailings streams and lower grade concentrates being produced. Additionally, the flowrates and compositions of con- centrates and tailings streams can have significant

What Is the Bulk Density of Coal? Reference

The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter.
