ReMFra project

Recovering metals and mineral fraction from steelmaking residues

Project description

Recovering metals and mineral fraction from steelmaking residues

The ReMFra project is a research project within the Clean Steel Partnership (Horizon Europe) to develop and validate a highly efficient, industrial-scale pyrometallurgical smelting and reduction process for the recovery of metals and minerals contained in a variety of steelmaking residues. The treatment route is based on two sub-processes (see Figure 1): a plasma reactor for processing coarse residues such as scale, sludge and secondary metallurgical slag, and the RecoDust process for processing fine-grain residues.

The work of K1-MET GmbH in the project focuses on smelting campaigns with the RecoDust pilot plant at the Chair of Thermoprocess Technology (project partner Montanuniversität Leoben) with various input materials (dust from the LD converter, the electric arc furnace or the HIsarna smelting reduction process), on DEC activities (Dissemination, Exploitation, Communication) and the monitoring of performance indicators (Key Performance Indicators, KPI).


The specific objectives of the ReMFra project are:

  • Development and implementation of highly efficient technologies for recovering metals and mineral fraction from steelmaking residues
  • Full by-product testing and evaluation
  • Use of smart sensor and dedicated Big Data analytics to develop and optimize decision-supported systems
  • Enabling the use of obtained slag in higher value applications
  • Reduction of CO2 emissions
