Leaching properties of secondary lead slag
Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste. The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously stabilized/solidified in concrete using additives: MgO, CaO, Ba(OH)2 and gypsum. The influence of selected additives on pollutant release was also …
