RIO TINTO INTENDS TO CONSTRUCT A PILOT PLANT FOR THE PRODUCTION OF LOW-CARBON IRON

Using ores obtained from mines in Australia's Pilbara region, Rio Tinto, an Australian mining company, has successfully shown the efficiency of their low-carbon iron-making process, known as BioIron.

In a small-scale pilot plant in Germany for the past 18 months, the demonstration has been conducted.

The BioIron process was thoroughly tested by a project team from Rio Tinto, the sustainable technology company Metso Outotec, and the Microwave Process Engineering Group at the University of Nottingham.

Rio Tinto now intends to build a larger-scale pilot plant to assist in decarbonizing the steel value chain when the method has been demonstrated.

As an alternative to metallurgical coal, raw biomass is used in BioIron as a reductant and a source of microwave energy. In the process of producing steel, this will transform iron ore into metallic iron.

Rio Tinto expects BioIron to provide almost carbon-neutral steel production. Additionally, when connected to carbon capture and storage, it is anticipated to produce net negative emissions.

A thorough and impartial technical study was done by international engineering, project management, and professional services firm Hatch, which confirmed the BioIron process' potential.

At a specifically created continuous pilot plant with a capacity of one ton per hour, Rio Tinto aims to test the BioIron process on a wider scale.

The mining company is now looking for potential sites to build the pilot plant, whose design is still being worked on.
