 Fluorspar.—Illinois ranked first among the eight producing States
in the Nation, supplying 71 percent of the total domestic fluorspar output.
Total Illinois shipments increased over 19 percent in quantity and 23 percent
in value. Acid-grade fluorspar accounted for 57 percent of the sales; ceramic
grade, 41 percent; and metallurgical grade, less than 2 percent. Sales of
acid grade increased over 16 percent, and those for ceramic grade 21 percent.
Sales of metaliurgical-grade fluorspar nearly doubled. 
 About 726,000 tons of crude ore was milled to produce 211,000 tons of finished
fluorspar as well as byproduct lead and 
zinc concentrates. All of the finished fluorspar was produced in Hardin County,
although crude ore came from Hardin and Pope Counties in Illinois and from
Kentucky. A small amount of Illinois crude ore was processed in Kentucky.
Producers included Hastie Mining Co., Minerva Oil Co., Ozark-Mahoning Co.,
J. W. Patton & Sons, J. D. Quarant, Ridge Fluorspar Mining Co., and Shawnee
Fluorspar Mining Co. The Aluminum Company of America and several small producers
removed crude ore from stockpiles. 
 
 Lime.—Quicklime and hydrated lime were produced at six plants in Adams
and Cook Counties. Total production increased about 1 percent. Over 61 percent
was used for chemical and industrial purposes, 33
