Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
