Embodiment 1
[0025] Production method of the present invention is:
[0026] (1) Pull out the carbon slag from the electrolytic cell, break it after cooling, then crush it to 3mm with a pair of rollers, and then grind it to the most suitable particle size for flotation with a ball mill, i.e. 0.45-0.76mm;
[0027] (2) Add a mixing drum, which contains flotation reagents, and the ground carbon residue and the reagents are fully stirred in the mixing drum;
[0028] (3) After stirring, it enters the flotation machine. There are two kinds of carbon slag flotation products, namely electrolyte containing a small amount of carbon and carbon powder containing a small amount of electrolyte. The electrolyte containing a small amount of carbon is further finely processed to prepare cryolite, which contains a small amount of carbon. The carbon powder of the electrolyte is used to prepare carbon, etc.;
[0029] (4) Fine product processing
