The production process of potassium alkaline liquor from leaching alkaline potassic rock with production of zeolites as a by-product

摘要

"Production process of potassium alkaline liquor from leaching alkaline potassic rock with production of zeolites as a by-product.The present invention consists of a process of preparing an alkaline liquor of potassium from potassium feldspar by reaction under pressure with a solution of alkali (for example N ~ ~ oh) productionZINDO alkaline liquor which after the steps of acidification and fractional crystallization, so that potassium salts, and production of by-product with commercial value: zeolites.
