to 320 million tons, and steel slag about 140 to 220 million tons, based on typical ratios of slag to crude iron and steel output [3]. Dumping of these wastes has problems starting with the limited area to store and deterioration of the environment is also another factor to be considered [4]. Steel slag is a solid waste from steel production.
