Abstract
The invention discloses an electrolytic manganese waste residue reuse method which comprises the following steps: taking 96-100 parts by weight of electrolytic manganese waste residues and 2-5 parts by weight of a fine powder sulfur-fixing agent; then sending the prepared electrolytic manganese waste residues and fine powder sulfur-fixing agent to a scattering device to be scattered and stirred evenly, then sending the mixture to a vertical drying machine, and drying and crushing at the temperature of 400-500 DEG C; putting the dried and crushed electrolytic manganese waste residues into a rotary kiln, carrying out high-temperature calcination, and then cooling the transferred-out manganese residues in a rapid cooling manner; carrying out surface modification on the cooled electrolytic manganese waste residues; and carrying out melt blending on the surface-modified 900-1100-mesh manganese slag ultrafine powder and PP or HDPE or PVC to prepare a corresponding manganese slag ultrafine powder / PP composite material or manganese slag ultrafine powder / HDPE composite material or manganese slag ultrafine powder / PVC composite material. According to the method, pollution of the electrolyticmanganese waste residues to soil and water resources is greatly reduced, and maximum utilization of the manganese residues is achieved.
Description
technical field [0001] The invention relates to the technical field of electrolytic manganese slag application, in particular to a method for reusing electrolytic manganese waste slag. Background technique [0002] Electrolytic manganese refers to the elemental metal manganese obtained by manganese ore leaching with acid, and then sent to the electrolytic cell for electrolysis. The electrolytic manganese waste slag is a mixture of acid leaching slag, sulfide slag and anode slag produced after manganese carbonate ore undergoes acidolysis, neutralization, pressure filtration, and impurity removal. The average amount of manganese slag discharged per ton of electrolytic manganese production is about 7.5-9 tons. Electrolytic manganese waste slag belongs to industrial pollution waste. A large amount of manganese slag discharge not only occupies land resources, but also pollutes soil and water resources. Therefore, it is urgent to propose a disposal method for electrolytic mangane...
