fuller's earth 
The activity in the fuller’s earth industry during 1920 was much 
greater than that of the preceding year, which was the most active year 
of the industry up to that time. There was a marked increase, both in 
the quantity of the earth mined and in the value. Florida has been the 
chief producer of fuller’s earth since the beginning of the industry, 
being credited with 85 per cent of the production of the United States 
for the year 1920. The use of the Florida earth is principally in clari¬ 
fying mineral oils, although its use in clarifying vegetable oils is con¬ 
tinuing. The value of production for 1920 is not given separately, but 
is included in the total mineral production. 
The following companies are engaged in the mining of fuller’s earth 
in Florida: 
The Atlantic Refining Company, Ellenton, Manatee County. 
The Floridin Company, Quincy and Jamieson, Gadsden County. 
The Fuller’s Earth Company, Midway, Gadsden County. 
The Manatee Fuller’s Earth Corporation, Ellenton, Manatee County. 
ILMENITE 
The production of ilmenite and other rare earths from the beach 
sands near Pablo Beach, Duval County, which was begun in 1916 and 
which was active in 1919, was not continued in 1920. Buckman & 
Pritchard, Inc., are pioneers in this industry in Florida and deserve 
much credit for the work already accomplished.
