DIATOMITE
PROBLEMS
A major problem of the industry is coordi-
nating production with the growing demand.
Another need of the industry is to find prof-
itable outlets for the very large tonnages of
low-grade earths and diatomaceous overburden
that must be excavated, moved, and provided
for during mining operations.
One of the industry's difficulties is its high
transportation cost burden, as all current pro-
duction comes from the West while the prin-
cipal markets are in the highly industrialized
East and Midcontinent areas.The industry has numerous processing prob-
lems that require the development of special
methods. For example, the high ratio of water
in some newly mined diatomite, the relative
fragility of the material, and the complex
specifications that the final products must meet.
As diatomite is usually 90 percent or more
free silica, it is a silicosis hazard that requires
rigid precautions to prevent silicosis among
workers, particularly in plant areas where dust
from calcined diatomite may be present (1).BIBLIOGRAPHY
