 The new aggregate plant of Gil Brown Constructors, Inc., at West Branch
employed a sink-float process for removal of chert and lightweight particles
from gravel. According to company reports, approximately 7 percent of the
150-ton-per-hour feed to its heavy-media separation system is rejected in
the form of chert and soft stone. 
 
 Stone.—Limestone was quarried in 17 counties by 24 commercial producers
and four county highway departments. Limestone, which accounted for nearly
all of the State stone output, came from large quarries in Alpena, Chippewa,
Mackinac, Monroe, and Presque Isle Counties. Nearly 77 percent of the material
was moved by water from company-operated ports on Lakes Huron and Michigan
to cement and 
lime plants, steel mills, and other consumers. 
 Demand for limestone decreased, with smaller requirements of the steel industry
for fluxstone, of roadbuilding for aggregates, and of cement plants for cement
stone, being responsible for much of the loss. The only major increase was
in limestone for manufacturing lime. 
 Small quantities of dimension limestone and sandstone were produced for
building purposes. The limestone was quarried and processed in Eaton, Huron,
and Presque Isle Counties. The sandstone was produced in Jackson County.
A small quantity of granite was quarried and crushed in Dickinson County
for use as facing aggregate in architectural concrete. In Houghton County,
basalt was quarried and crushed
