Free online calculators for coal and mineral processing. Enter your float-sink, size or plant data and get results, charts and tables in seconds, built by Red Dune’s process engineers.
Theoretical yield, separation density and discard ash for any target product ash. Single or two-product separations, with near-gravity material.
Open toolTromp curve, cut-point density d50, Ep, imperfection, organic efficiency and misplaced material from a plant test.
Open toolFractional or cumulative float–sink data to full washability tables and curves, with product quality and near-gravity material at any density.
Open toolCumulative passing, mean size, d50 and P80, Rosin-Rammler fit, and the size consist after crushing to a top size.
Open toolBlend CV, ash, sulphur and moisture from up to ten products, as-received CV, and the ratio to hit a target specification.
Open toolMaximum combined yield from two or more separately washed coals at a target ash or CV, the best cut point for each, and what the extra tonnes are worth.
Open toolYield and separation density for a target product CV, from float-sink data.
Primary wash, floats rewash and two-stage low-high wash simulations from washability data.
