Laboratory Simulation of In-situ Leaching of Polyhalite
Procedia Earth and Planetary Science, 2011 AbstractDeeply buried polyhalite is a kind of sulfate which contains about 28% potassium sulfate. Extraction potassium from polyhalite using in-situ leaching technology can help to resolve the problem of potassium shortage. This paper indicates a modeling study of leaching polyhalite in laboratory.
