2019 1 1 Abstract. An integrated steel plant generates 200–250 kg of steel making slag for every tonne of steel produced. These slags contain non uniformly distributed iron in metallic form inevitably carried into the slag pot during de slagging. The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products
