Embodiment 1
[0034] A method for preparing environmentally friendly bricks from potassium feldspar tailings, comprising the following technical steps:
[0035] 1) Treatment of potassium feldspar tailings: After the production of potassium feldspar, the tailings or tailings are sent to the ball mill, the ball-to-material ratio is 4:1, the initial slurry concentration is 60%, and propylene glycol-containing alginate is added dispersant, the amount of dispersant containing propylene glycol alginate is 0.5% of the mass of the abrasive, and it is finely ground to more than 80 mesh;
[0036] 2) Mixing for the first time: fully mixing the material obtained in the previous step with sludge with a moisture content of 70% to obtain sandy clay with a moisture content of 40%;
[0037] 3) mixing for the second time: the sandy clay and fly ash obtained in the previous step are mixed according to the mass ratio of 60%, 40%, and stirred evenly to form a mixture;
[0038] 4) Digestion: Add the second mixe...

[0060] A method for preparing environmentally friendly bricks from potassium feldspar tailings, comprising the following technical steps:
[0061] 1) Treatment of potassium feldspar tailings: After the production of potassium feldspar, the tailings or tailings are sent to the ball mill, the ball-to-material ratio is 5:1, the initial slurry concentration is 60%, and propylene glycol-containing alginate is added dispersant, the amount of dispersant containing propylene glycol alginate is 0.6% of the mass of the abrasive, and it is finely ground to more than 80 mesh;
[0062] 2) Mixing for the first time: fully mixing the material obtained in the previous step with sludge with a water content of 80% to obtain sandy clay with a water content of 40%;
[0063] 3) mixing for the second time: the sandy clay and fly ash obtained in the previous step are mixed by mass ratio of 75%, 25%, and stirred evenly to form a mixture;
[0064] 4) Digestion: Add the second mixed material after sti...
