The efficiency of quartz addition on electric arc furnace (EAF) carbon steel slag stability [PDF]
Journal of Hazardous Materials, 2014 Electric arc furnace slag (EAF) has the potential to be re-utilized as an alternative to stone material, however, only if it remains chemically stable on contact with water. The presence of hydraulic phases such as larnite (2CaO SiO2) could cause dangerous elements to be released into the environment, i.e. Ba, V, Cr.

Microwave-Supported Leaching of Electric Arc Furnace (EAF) Slag by Ammonium Salts [PDF]
Minerals, 2017 The effect of microwave-supported leaching of electric arc furnace (EAF) slag by ammonium salts was investigated to improve calcium leaching ratio for CO2 mineral sequestration process. The results show that the calcium leaching ratio from EAF slag at the constant temperature in the microwave field increases about 10% than that under the water bath at ...
