Problems solved by technology

[0005] The purpose of the invention is to develop a method for comprehensive utilization of manganese oxide slag recovery, utilizing comprehensive separation technology to reclaim about 30% manganese oxide concentrate (metal manganese content is more than 30%) and heavy metals such as iron in the manganese oxide slag. The remaining secondary tailings after sorting partially replace gypsum as cement retarder, or as wall materials, or as slag cement to partially replace traditional cement; fundamentally solve the pollution problem of manganese oxide slag to the environment, and make manganese oxide slag The resources in the manganese oxide slag are fully and reasonably utilized, saving land resources, improving the comprehensive recycling value of manganese oxide slag, and basically realizing zero discharge of manganese oxide slag

Abstract

The invention relates to a comprehensive utilization method for recycling manganese oxide 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 30 percent of manganese oxide concentrate (content of manganese metal is over 30 percent), iron and other heavy metals in the manganese oxide slag 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 manganese oxide slag, make full and reasonable use of the resources in the manganese oxide slag, save land resource, improve the comprehensive utilization value of the manganese oxide slag and realize zero discharge of the manganese oxide slag.

Description

technical field [0001] The invention relates to the technical field of recovery and comprehensive utilization of industrial waste slag, in particular to a comprehensive utilization method for recovery of manganese oxide slag. Background technique [0002] Manganese oxide (manganese dioxide) is the main component of pyrolusite, which is a common manganese mineral, and some manganese oxide ores contain more than 60% manganese, which is an important manganese ore. Manganese oxide ore is formed from other manganese ores. Manganese oxide ore can also be formed in the sediments formed in swamps, lakes and seas. After electrolytic refining, its products can be used to prepare high-purity manganese oxide concentrate. It is the production of manganese sulfate, Electrolytic manganese metal, active manganese dioxide, electrolytic manganese dioxide, manganese tetroxide and other main raw materials are widely used in steel industry, aluminum alloy industry, magnetic material industry, ch...
