Method for preparing brick from pyrite cinder magnetic separation mine tailing
The invention discloses a method for preparing a brick from pyrite cinder magnetic separation mine tailing. The method comprises the following steps of 1, putting sulfuric-acid residue as an initial raw material into a bowl mill, and carrying out ore grinding under the control of slurry concentration in ore grinding and slurry mixing, 2, after ore grinding, feeding the ore slurry into an ore feeding agitating tank of a wet magnet separator under the control of ore slurry concentration, 3, carrying out magnetic separation under the control of fed ore slurry concentration of the magnet separator agitating tank, and ore slurry feeding, medium shocking and fine shocking time, 4, filtering middlings and mine tailing as mine tailing by a filter, putting the filter residue into an oven and carrying out drying, 5, mixing the mine tailing as a raw material, cement, fly ash and lime, 6, adding water, gypsum and additives into the mixture, carrying out stirring to obtain a uniform mixture, carrying out aging and putting the aged product into a mold, and 7, carrying out standing for a day, taking the product out of the mold, putting the product into a maintenance case and carrying out maintenance. The method is simple and practical, has strong comprehensive usability, can produce high-grade iron concentrate, can produce a good-quality non-burnt brick, solves the problems of sulfuric-acid residue stockpiling and environment and creates good economic benefits.
