Abstract

The invention provides an electrolytic manganese residue and shale sintered product and a production method thereof. The electrolytic manganese residue and shale sintered product comprises the following components in parts by weight: 50-70 parts of shale, 30-50 parts of electrolytic manganese residue and 12-20 parts of barium carbonate. The production method comprises the working procedures of electrolytic manganese residue pretreatment, burdening, aging, extrusion forming, drying, roasting and the like. According to the sintered product, large-scale application of solid waste resources of the electrolytic manganese residues can be achieved, the problems that in the sintered product of the electrolytic manganese residues and the shale, the drying shrinkage rate of the product is large, the cracking phenomenon occurs, and the strength is low are effectively solved, the scumming harm of the finished product can be eliminated or relieved, and ugly white spots are prevented from being formed on the surface of the product.

Description

technical field [0001] The invention relates to the field of resource utilization of electrolytic manganese slag, in particular to a sintered product of electrolytic manganese slag and shale and a production method thereof. Background technique [0002] At present, the electrolytic manganese enterprises in my country basically use landfill to deal with manganese slag. The key to landfill disposal lies in the construction of slag yards. my country has strict regulations on the construction of slag yards. According to the "General Industrial Solid Waste Storage and Landfill Pollution "Control Standard" (GB 18599-2020) is implemented. For electrolytic manganese enterprises with a scale of 10,000 tons / year, the manganese slag dump site designed and established according to the standard, only the anti-seepage system and leachate collection system will require tens of millions of investment In addition to the annual maintenance cost of millions, it is difficult for enterprises to be...
