METHOD FOR PRODUCING OF AMELIORANT FOR TREATING OF SOLONETZ SOIL AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC C05F11/02 C05G1/00 B04C7/00 

FIELD: production of ameliorant based on natural bischofite, phosphorites, metallurgical production wastes in the form of slag, used etching solutions employed in etching of ferrous metals with sulfuric acid, and used electrolytes utilized in galvanic plating.

SUBSTANCE: method involves processing solid components followed by mixing with liquid components; preliminarily preparing solution from used etching solutions of sulfuric acid etching of ferrous metals and electrolytes of galvanic plating in the ratio of 1:1; separately feeding solution for treating of ground metallurgical slag at solid and liquid phase ratio S:L=1:6 and for processing of ground phosphorites at S:L ratio of 1:7; in the first case, heating mixture to temperature of 120-160 C during 0.75-1.25 hours, in the second case heating mixture to temperature of 95-120 C during 30-45 min while continuously mixing until homogeneous mass is produced; preparing third mixture of ground phosphorites and mixing it with brine of natural mineral of bischofite of MgCl₂·6H₂O formulation at S:L ratio of 1:4, said mixing process being conducted at temperature of 80-90 C during 1-2 hours; mixing resulted pulp of bischofite and phosphorites with homogeneous mass of slag of metallurgical production with etching solutions and phosphorites with etching solutions in the ratio of 1:1:1 during 1 hour at temperature of 45-70 C until pasty mass is produced. Also, apparatus for producing of ameliorant is described.

EFFECT: improved quality of ameliorant, reduced consumption of power and decreased production costs in obtaining of ameliorant.
