METHOD OF PROCESSING MANGANESE-CONTAINING MATERIALS Russian patent published in 2016 - IPC C22B47/00 C22B3/06 C01G45/02

Abstract RU 2598063 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of processing manganese-containing materials, for example sea bottom manganese concretions. Method involves leaching of these materials with the help of an aqueous solution of nitric acid and polymerized nitrogen oxide (N₂O₃)_x. Herewith also extraction is performed of useful components from the said nodules, especially manganese, cobalt, nickel, iron and copper.

EFFECT: technical result is separation from the manganese oxides of such metals as titanium, vanadium, cerium, molybdenum and other valuable ones and available for extraction, as well as obtaining a product, which meets the mineral fertilizer condition.
