Solar metallurgy

Very broadly defined, solar metallurgy includes both photothermal processes (e.g. photothermal iron reduction, photothermal concentrate titanium white waste acid) as well as photovoltaic processes (e.g. photovoltaic steel-making and preparation of pure iron by photovoltaic electricity). The benefit of photothermal energy is that working with metals often requires high temperatures, controlled atmospheres, and freedom from contamination. A solar concentrator (such as a heliostat) may provide these conditions.
