Chemicals Corp. announced plans for expanding its calcined kaolin production
capacity a-t McIntyre, Ga. Anglo-American Clay Corp. also announced expansion
of its facilities at Sandersville. This expansion included new spray-drying
equipment plus additional equipment to increase the production capacity of
their high-brightness coating clays. Freeport Kaolin Co. and Georgia Kaolin
Co. were installing largecapacity wet magnetic separators at their Georgia
plants, while the J. M. Huber Corp. was expanding its existing magnetic separator
facilities. Theile Kaolin Co. was also reportedly planning installation of
magnetic separators at its Sandersville plant. High-intensity wet magnetic
separators are used to remove iron-bearing contaminants from kaolin clays.
Dresser Industries Inc. placed its new kaolin-calcining facility on stream
at Kossee, Tex.

The kaolin producers reported the end use of their exports were paper coating,
48%; paper filling, 25%; rubber, 8%; and others, including firebrick, paint,
and plastics, 19%.
