Among others, building applications ...
Therefore, industrial waste recycling offers solutions to pressing industrial, socio-economic, and environmental challenges in regions, as well as representing significant industrial potential. The developed solutions ensure the recycling of nickel slag for ceramic technology, as well as its controlled storage in dumps [ 7 ].
Magnetic Slags From Similar Industrial Waste Trade Data from global. Trade Data Pro platform for HS code, importer exporter records, customs shipment details Vietnam Magnetic Slags From Similar Industrial Waste Product import History Records.
Large amounts of waste slag are produced when this melting slag is discharged and cooled. These slags are normally composed of CaO, SiO 2, FeO, and other oxides from the pyrometallurgical industry. Due to undergoing high-temperature processing, these slags have relatively stable physical and chemical properties.
Industrial waste slags including ferronickel (Greece) and fayalite (Finland) slags were mixed with ground waste concrete for the production of inorganic polymers (IPs).
