Abstract

The oversupply of steel product has led the global steel industry to a significant decline in revenue and profit. To make things harder, increasing demand to reduce greenhouse gas emissions has intensified pressure on steelmakers. As an effort to make progress from economical and ecological perspectives, the ironmaking field is expanding the recycling of ferrous by-products. Copper slag has been widely recycled in the abrasive media, the pavement, and the cement industries. However, there was no successful activity of recycling copper slag in the steel industry. The FINEX process is known for the flexibility of recycling ferrous by-products. There are chances that the ferrous by-products that cannot be recycled in the blast furnace due to inferior mechanical, thermal, and chemical properties can be recycled in the FINEX process. In the present study, the feasibility assessment of recycling copper slag in the FINEX process has been performed on an industrial pilot-scale.
