Embodiment 1

[0024] A kind of method of anhydrous production polymagnesium chloride that the present invention proposes, comprises the following steps:

[0025] Step 1: Take magnesium-containing minerals / minerals or other magnesium-containing materials as a step, and selectively plasticize at a temperature of 350°C to 900°C. The plasticization reaction obtains magnesium chloride mixed extrusion solvent ammonium chloride, and dissolves 90% of the reaction mixture In the polar organic solvent, 10% or less is suspended, and the polar organic solvent is an anhydrous solvent;

[0026] Step 2: selectively extracting and leaking magnesium from the plasticized material in anhydrous state solvent and separating insoluble impurities in the extruding solvent after mixing it, and separating the two;

[0027] Step 3: Precipitation of magnesium chloride by NATE dehydration;

[0028] Step 4: and processed as excess ammonia in the crystallizer;

[0029] Step 5: the suspension obtained in step 4 is filte...

Abstract

The invention relates to the technical field of environmental-friendly treatment agents and in particular relates to a method for producing polymerized magnesium chloride through anhydrous production.The method has the advantages of being rapid, small in pollution and small in waste gas amount. The method for producing polymerized magnesium chloride through anhydrous production comprises the following steps: 1, carrying out selective plasticization on a magnesium ore / ore or other magnesium-containing material at 350-900 DEG C, carrying out a plasticization reaction so as to obtain magnesium chloride mixed extrusion solvent ammonium chloride, dissolving a reaction mixture into a polar organic solvent for 90%, and carrying out suspension for 10% or less, wherein the polar organic solvent isan anhydrous state solvent; 2, separating magnesium from the anhydrous state solvent from a plasticizing material selectively, and extruding insoluble impurities in the solvent, and separating the magnesium from the insoluble impurities; 3, carrying out NATE dehydration precipitation so as to obtain a magnesium chloride salt; 4, treating in a crystallizer as excessive ammonia; 5, filtering the suspension obtained in the step 4, and extruding and separating magnesium chloride from the solvent by using a centrifugal method in a configure.
