1. Introduction. Steel slag is a by-product of the steelmaking process. In fact, each ton of steel produces 110–150 kg of steel slag. China's steel slag reserves are more than 300 million tons, and the annual hoard continues to increase [1].Due to the different steel composition, scattered varieties of converter slag and complex composition exist, …

The chemical multi-element analysis of raw ore, transformed products, iron concentrate, and tailings is shown in Table 2. Table 2 shows that the TFe content in the raw ore was 48.15 %, and the FeO content was less than 0.01 %. This indicated that iron in the raw ore was not present in FeO, indicating a very low content of highly magnetic …
