Sizing Calculators

6 calculators covering Leaching (1) · Solid-Liquid (1) · Liquid-Liquid (2) · Evaporation (1) · Electrowinning (1). Each one runs entirely in your browser and prints the assumptions it depends on.

These are pre-feasibility estimators, not guarantees — every calculator returns the number it can defend and the conditions under which that number holds. Where a result depends on data only your own material can supply (filtration rate, leach kinetics, distribution coefficient), the output says so instead of substituting an industry average. Nothing you type is uploaded: the arithmetic runs in your browser.
TL-O-A-RATIO-AND-STAGE-COUNT

O/A Ratio and Extraction Stage Calculator

Work out the extraction factor, theoretical stage count, raffinate concentration and loaded organic loading from your distribution coefficient and O/A ratio. Kremser method with stated assumptions.

Want the sizing done against your own test data?

Send the feed material, throughput and medium. We return a configuration, the calculation behind it and — if you have no test data yet — the lab campaign that would produce it.
