"Steel produces around 10 percent of global emissions, so that is our north star," Lambotte says. "Everyone is pledging carbon reductions, emissions reductions, and making net zero goals, so the steel industry is really looking hard for viable technology solutions. People are ready for new approaches."

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Pig iron, an intermediate form of iron produced from iron ore and is subsequently worked into steel or wrought iron 10. Uses: Traditionally pig iron would be worked into wrought iron in finery forges, and later puddling furnaces, more recently into steel. In these processes, pig iron is melted and a strong current of air is directed over it ...
