Question

Which option is the least likely use for a blast furnace?(1 point)

to minimize emissions during smelting

to separate impurities from metals

to smelt metal into workable forms

to create alloys from multiple metals

Answer 1

to minimize emissions during smelting

Blast furnaces are used to smelt ore, separate impurities (slag), and produce molten metal (and feedstock for alloys), but they are major sources of emissions rather than devices designed to minimize them.
