Abstract
In this study, an experiment was conducted to manufacture an iron ore substitute by increasing the Fe quality in the steelmaking dust treatment DRI through classification and magnetic screening. 1 kg of steelmaking dust treatment DRI was separated, and the weight ratio and Fe content by granularity were investigated. Afterwards, a magnetic screening experiment was conducted with 100 g of DRI separated based on the derived optimal separation conditions. For magnetic screening, the weight and Fe content of the magnetic powder for each Gauss were investigated using the magnetic strength (Gs) as a variable using an electromagnet and a Gauss meter; there are capable of controlling the magnetic strength. As a result of the experiment, the Fe content in DRI was improved from 43.29 wt.% to 61.02 wt.% through separation and magnetic screening, thus achieving the requirements of iron ore substitute.
