These articles start from what you are seeing — a growing dispersion band, wet cake, falling current efficiency, scale on the tubes — and work back to the cause in a defined order. Each one lists the measurement that distinguishes one cause from another, so you can stop changing three variables at once.
Scaling in Evaporators and Crystallizers: Supersaturation Is the Only Lever That MattersMost fouling is caused by running too hard. Control supersaturation and seed inventory, and cleaning intervals lengthen dramatically.Leach Recovery Below Target: A Checklist from PSD to PassivationRecovery losses are usually particle size, reagent excess or residence time. Work the checklist before adding acid.Low Current Efficiency in Electrowinning: The Five Losses You Can Actually MeasureCurrent efficiency below 90% is a symptom of shorts, impurities or poor mass transfer. Here is how to tell which one you have.Filter Cake Too Wet: Eight Causes Ranked by How Often They Are the AnswerMoisture problems are usually cloth, cycle time or slurry condition — not press pressure. A structured check saves a week of trial and error.Crud in Solvent Extraction: Where It Comes From and How to Get Rid of ItCrud is not one problem — it is three. Identify whether yours is solids-stabilised, silica-based or organic-degradation crud before treating it.Settler Flooding: Why the Dispersion Band Grows and How to Bring It BackA widening dispersion band is a hydraulic symptom with five common causes. Work through them in this order before touching the flow rate.
