Recycling utilization method of digestion waste slag
The invention discloses a recycling utilization method of digestion waste slag. The recycling utilization method of the digestion waste slag comprises the following steps that the digestion waste slag generated in the light calcium carbonate production process is dried; a heat source for drying is hot air being 180 to 220 DEG C; the time of the digestion waste slag from the generation to the beginning of the drying needs to be controlled within 20 minutes. The recycling utilization method of digestion waste slag has the advantages that the environment protection problem of the digestion waste slag generated in the light calcium carbonate production process can be effectively solved; the digestion waste slag can be effectively utilized; good economic benefits are realized.
