An overview of recovery of metals from slags - ScienceDirect
BF slag contains little metal and recovery of metal from it is not important. Steel slag is usually subjected to metal recovery prior to its application outside the iron and steel making process. By applying mineral processing technologies such as crushing, grinding, classification and magnetic separation, it is possible to produce steel scrap (Fe: 90%) and iron concentrate (Fe>55%) from steel slag.

Electric Steelmaking - Primetals Technologies
The continuously measured EAF offgas analysis and flow are used in the holistic process model for closed-loop control of the burners and oxygen injector units. The injection of carbon is also controlled for optimized foaming slag management. The application of this system is geared towards improvement of energy, electrode, oxygen and natural gas consumption as well as metallic yield and productivity.
Electric Arc Furnace Dust - an overview | ScienceDirect Topics
The most popular process for zinc recovery is the so-called Waelz kiln, located usually outside the steel plant boundaries. These furnaces have been developed in the early twentieth century by zinc producers to enrich low Zn ore (Figure 1.5.21). They have been adopted in the 1950s for EAF dust treatment.
