Systems and methods for processing sylvinite and carnallite ores

摘要

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.

主权项

1. A system for processing ore comprising:
a supply containing a volume of a lye solution; a first dissolving apparatus having first and second inlets and first and second outlets, the first inlet receiving ore to be processed, the second inlet receiving lye solution from the supply, the first inlet being positioned above the second inlet, the lye and ore mixing in a counter current flow to produce a supersaturated solution and undissolved ore; a first dehydrator having an inlet and an outlet, the inlet of the first dehydrator receiving the undissolved ore from the first outlet of the first dissolving apparatus; a second dissolving apparatus having first and second inlets and first and second outlets, the first inlet receiving the undissolved ore from the outlet of the first dehydrator, the second inlet receiving lye solution from the supply, the first inlet being positioned above the second inlet, wherein the lye solution and undissolved ore are mixed in a counter current flow to produce a supersaturated solution and undissolved ore; a second dehydrator having an inlet and an outlet, the inlet of the second dehydrator receiving undissolved ore from the first outlet of the second dissolving apparatus; a crystallizer having an inlet and an outlet, the supersaturated solution from the second outlets of the first and second dissolving apparatuses being delivered to the inlet of the crystallizer, the crystallizer cooling and crystallizing the supersaturated solution.
