безхлоридна калімагнезія.

Дослідження процесу екстрагування хлоридів з виробничого шеніту з одержанням безхлоридного калійно-магнієвого добрива

In this paper the results of experimental studies of the extraction process of chlorides from the production schoenite that contains more than 15 wt. % Cl-, with using 20 ... 50 % aqueous solutions of isopropyl alcohol are given. It is shown that the realization of extraction in 30 % extractant in ratio between solid and liquid phases  that is equal 3, makes it possible to obtain a precipitate, which after dehydration contains on the dry weight (wt.
