摘要

FIELD: chemistry. ^ SUBSTANCE: method involves treatment of the material by washing with water, burning the insoluble residue and leaching the ash. Before leaching, the ash undergoes secondary treatment by washing with water in solid to liquid ratio equal to 1:0.7-2.5. ^ EFFECT: reduced volume of pulp obtained during leaching, increased extraction of noble metals and recycling of potassium chloride. ^ 2 tbl, 2 ex
