METHOD FOR ENRICHING ASH AND SLAG MIXTURES OF THERMAL POWER PLANTS FOR PRODUCTION OF CONSTRUCTION BINDERS Russian patent published in 2023 - IPC B03B9/04 

FIELD: treatment of power plant waste.

SUBSTANCE: proposed invention relates to the field of enrichment of ash and slag mixtures of coal thermal power plants for the purpose of their utilization as concrete fillers for the production of construction binders. A method for enriching ash and slag mixtures of thermal power plants for the production of construction binders includes grinding ash and slag mixtures in a ball mill to a fraction of less than 0.16 mm, flotation at a mixing intensity of 1700 rpm for 5 minutes, magnetic separation in “ПБМ-П-25-10” when exposed to on the ash and slag mixture with a magnetic induction of 0.5 T, dehydration and drying in a muffle furnace at 250°C for 50 min.

EFFECT: utilization of ash and slag mixture to improve the environmental situation, as well as the production of ash and slag mixture for the production of construction binders with high strength values.
