[0056]A method for coordinated solidification treatment of electrolytic manganese slag and red mud includes the following steps:
[0057](1) Take the electrolytic manganese slag and old red mud to dry until the water content is below 20wt%, and then transport the electrolytic manganese slag, old red mud and quicklime to the crusher for crushing treatment to obtain electrolytic manganese slag powder and old red mud. Mud powder and quicklime powder, the particle size of electrolytic manganese slag powder is 50 mesh, the particle size of old red mud powder is 50 mesh, and the particle size of quicklime powder is 140 mesh; then take 10kg of electrolytic manganese slag powder and old red mud powder Add 3kg to the mixer, and then add 2L of the first red mud leachate, the pH of the first red mud leachate is 10, and the first stirring is performed at a stirring rate of 100r / min, stirring time is 10-15min, and ammonia gas is recovered , Get the first mixture;

[0062]A method for coordinated solidification treatment of electrolytic manganese slag and red mud includes the following steps:
[0063](1) Take the electrolytic manganese slag and fresh red mud to dry until the water content is below 20wt%, and then transport the electrolytic manganese slag, fresh red mud and quicklime to the crusher for crushing treatment to obtain electrolytic manganese slag powder and fresh red mud powder And quicklime powder, the particle size of electrolytic manganese slag powder is 120 mesh, the particle size of fresh red mud powder is 100 mesh, and the particle size of quicklime powder is 80 mesh; then take 10kg of electrolytic manganese slag powder and 3kg of fresh red mud powder and add to In the mixer, add 2L of the first red mud leachate. The pH of the first red mud leachate is 12.5. Perform the first stirring at a stirring rate of 150r / min and a stirring time of 10-15min. The ammonia gas is recovered to obtain the first A mixture

[0068]A method for coordinated solidification treatment of electrolytic manganese slag and red mud includes the following steps:
[0069](1) The electrolytic manganese slag, old red mud and quicklime are respectively transported to the crusher for crushing treatment to obtain electrolytic manganese slag powder, old red mud powder and quicklime powder. The particle size of the electrolytic manganese slag powder is 120 mesh, which is old The particle size of the red mud powder is 120 mesh, and the particle size of the quicklime powder is 50 mesh; then take 10kg of electrolytic manganese slag powder and 6kg of old red mud powder into the mixer, and then add 3L of the first red mud leachate. The pH of a red mud leachate is 12.5, the first stirring is performed, the stirring rate is 150r / min, and the stirring time is 10-15 minutes, and ammonia gas is recovered to obtain the first mixture;
[0070](2) Transfer the first mixture obtained in step (1) to the first mixer, and then ad...
