Blast Furnace slag production ranges from about 220 to 370 kilograms per metric ton of pig iron produced; although lower grade ores may yield much higher slag fractions. Steel making process in electric arc furnaces generates up to 15 % of slag, which is, based on its properties, classified as non-hazardous waste.

1. Introduction. Steel slag is a by-product of the steel production process, accounting for approximately 15% of the whole crude steel output [1].The accumulation of untreated steel slag not only occupies a significant amount of land but also leads to the leaching of heavy metal ions (such as vanadium, chromium, arsenic, lead, cadmium), …
