CONSUMPTION AND USES 
 All major end uses reported significant fifths of the total material sold
or used by increases in consumption. However, the producers in 1972. The

PRICES 
 The weighted average value per ton of diatomite for all end uses in 1972,
increased only slightly from that of 1971. Small increases in value per ton
were reported for almost all end uses except for the abrasives which declined
10%.

FOREIGN TRADE 
 Exports of prepared diatomite increased 4% in quantity and 7% in value over
that of 1971 after declining since 1969. Major countries of destination for
these exports were: Canada 25%; West Germany 11%; Japan 9%; the United Kingdom
8%; Australia 6%; Italy 4%; and Republic of South Africa 3%. The remainder
was exported to many other developed and undeveloped countries of the world.
The average value of exported material was $85.16 per ton. Imports of crude
or processed material totaled 63 tons val 
ued at $9,440. This material was imported from Mexico, Kenya, Canada, the
United Kingdom, and West Germany. These imports were probably used to evaluate
the diatomite deposits of these countries.

WORLD REVIEW 
 Overall world production of diatomite remained relatively unchanged from
that of the previous year. 
 Increasing cost of transportation has tended to inhibit the growth of exports
of domestically prepared diatomite during the 
past few years. This situation has stimulated interest in other deposits
throughout the world. As a result of this trend the Johns-Manville Products
Corp. has begun operating diatomite deposits at Murat, France, and Elch de
la Sierra, Spain.
