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

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2016
Solid waste management is one of the subjects essentially addressing the current interest today. Due to the scarcity of land filling area, utilization of wastes in the construction sector has become an attractive proposition for disposal. Ferrochrome ash (FA) is a dust obtained as a waste material from the gas cleaning plant of Ferro alloy industries ...

Microelement Composition of Ash and Slag Waste of the Transbaikal Territory
Transbaikal State University JournalFossil coal consists of organic and inorganic parts. The inorganic part is in the form of minerals. In the composition of inorganic matter, two chemical groups of elements are distinguished: ash-forming or main, constituting about 99 % of all inorganic matter; impurity or minor elements (about 1 % of the total inorganic matter).
