Although Canadian bentonite is competitive in quality for most uses, it has not been accepted for the pelletizing of iron ore concentrates. In 1962, Canada consumed about 10,000 tons of imported bentonite for this use. By the end of 1965, the planned domestic consumption for this purpose alone will probably be more than 100,000 tons a year, valued at about $3 million. Consequently, a challenge exists for the establishment of a Canadian source of high-quality bentonite for pelletizing. Such a bentonite would also be suitable for the two other major applications - well drilling and foundry use. Brief mention is made of such topics as the identification, properties, occurrences, exploration, applications, technology and laboratory testing of this clay. In particular, the type of bentonite in demand, the geological horizons warranting exploration, and simple preliminary test methods are discussed.
