Electric Separation of Ash and Slag Waste Kashirskaya GRES
Ecology and Industry of Russia, 2023The advantage of electrical separation in the processing of classified ash and slag as the main separation operation was substantiated. It was recommended to switch to electrical separation as the first technological operation and carry out the entire cycle of ash and slag processing using dry methods due to their economic benefits compared to wet ones.

Leaching behavior of fly ash-waste glass and fly ash-slag-waste glass-based geopolymers
Ceramics International, 2018Abstract The leaching behavior of contaminants in the fly ash/waste glass or fly ash/blast furnace slag/waste glass-based geopolymers was investigated through surface area analysis and leaching tests. Spent fluorescent lamps classified as hazardous waste due to their specific contaminant contents were used as a source of waste glass. The results from

Obtaining Silicon-Carbide-Based Ceramics from Ash and Slag Wastes
Technical Physics Letters, 2020The possibility of obtaining solid silicon-carbide-based ceramics from ash and slag wastes (ASWs) is demonstrated. The technological process contains three stages: (i) nonvacuum processing of the initial ASWs in dc arc discharge carbon plasma under normal atmospheric condition, (ii) cleaning of the obtained powdered material from unbound carbon by ...
