Oto minimize emissions during smelting

Oto smelt metal into workable forms

Oto separate impurities from metals

Oto create alloys from multiple metals

"To minimize emissions during smelting."

Explanation: Blast furnaces are used to smelt iron, separate impurities (slag) and produce molten metal for further processing; they are not designed to reduce emissions and in fact generate large CO2 and other emissions.
