20140030164 | Systems And Methods For Processing Sylvinite And Carnallite Ores - Disclosed are systems and methods for processing carnallite or sylvinite ores. The system includes a measuring hopper, a lye clarifier, two vertical ore dissolving apparatuses, two ore dehydrators and one wet product dehydrator, a crystallizer, and a dryer. Each dissolving apparatus has alternating supply and grounding electrodes arranged in axial alignment with the apparatus. The ore is run through both dissolving apparatuses in succession and dehydrated after each dissolving apparatus. A dissolving lye is fed to each dissolving apparatus in countercurrent flow to the solid phase ore. The saturated lye from the dissolving apparatuses is transported to a crystallizer to be cooled. Cooling the lye forms crystalline potassium chloride or artificial carnallite, which then goes for dehydration and drying. | 01-30-2014 |
