National Emission Standards for Hazardous Air Pollutants: Taconite Iron

Taconite iron ore processing plants separate and concentrate iron ore from taconite, a low-grade iron ore containing 20- to 25-percent iron, and produce taconite pellets, which are 60- to 65-percent iron. Taconite iron ore processing includes crushing and handling of the crude ore, indurating, and finished pellet handling.

Water requirements of the iron and steel industry

Abstract. Twenty-nine steel plants surveyed during 1957 and 1958 withdrew from various sources about 1,400 billion gallons of water annually and produced 40.8 million tons of ingot steel. This is equivalent to about 34,000 gallons of water per ton of steel. Fifteen iron ore mines and fifteen ore concentration plants together withdrew annually ...
