Abstract

The invention relates to a comprehensive utilization method for recycling manganous carbonate slag. The method comprises the following steps: (1) screen separation; (2) dilution and agitation; (3) integrated separation; (4) dehydrating and drying; (5) package; and (6) repreparation of cement retarder or mixing and pressing of walling material or repreparation of slag cement. The method has the advantages that about 20 percent of manganous carbonate concentrate, iron and other heavy metals in the manganous carbonate slag reaching mine-entering grade (content of manganese metal is 17 percent) are recycled by using integrated separation technology, and the secondary tailing part remained after the integrated separation replaces plaster to be the cement retarder, or the walling material, or the slag cement; and the method can fundamentally solve the problem of the pollution on the environment caused by the manganous carbonate slag, make full and reasonable use of resources in the manganouscarbonate slag, save land resource, improve the comprehensive utilization value of the manganous carbonate slag and completely realize zero discharge of the manganous carbonate slag.

Description

Technical field [0001] The invention relates to the technical field of recovery and comprehensive utilization of industrial waste residues, in particular to a comprehensive utilization method for recovery of manganese carbonate residues. Background technique [0002] Manganese carbonate ore is a rare mixed primary manganese ore of high manganese, high sulfur, high silver, high lead and zinc in our country. After being refined by electrolysis, its product can be used to prepare high-purity manganese carbonate concentrate. It is used to produce manganese sulfate and electrolytic metal. Manganese, active manganese dioxide, electrolytic manganese dioxide, manganese tetroxide and other main raw materials are widely used in the steel industry, aluminum alloy industry, magnetic material industry, chemical industry and other fields. [0003] However, my country's manganese ore resources are poor and the grade of manganese ore is low. At the same time, the amount of waste slag produced by ...
