MINERALS YEARBOOK, 1972 
WORLD REVIEW 
 Australia.—A new beryl mine was opened 
near Perenjori, about 200 miles northeast of Perth. Seleka Mining and Investments,
Ltd., initiated a drilling program in 1972 to determine the extent of beryl
mineralization and was expected to produce beryl for export. 
 Brazil.—There were reports from the 
State of Minas Gerais of new beryl reserves 
to be developed with a Banco Nacional de 
Desenvolvimento E-conômico loan of 
$15,000. 
 Japan.—The Japan Society of Newer Metals announced the capacity for
production of a little more -than 1 short ton annually of beryllium metal
by electrolytic refining. The capacity for producing beryllium oxide was
nearly 80 short tons per year, mostly by the silicofluoride process. The
capacity for producing beryllium copper master alloy was about 800 tons per
year. Production figures for 1972 were not available. J-apan imports beryl
principally from Africa, Brazil, and Australia.

 ' Estimate. ~ Preliminary. ' Revised. W Withheld to avoid disclosing individual
confidential data. 
 ' In addition to the countries listed, the Territory of South West Africa
also may have produced beryl, but mineral production of this area has not
been officially reported since 1966, and no reliable information is available
as a basis for estimating output since that time. India, listed as a major
producer in previous editions of this table (with output estimated in the
order of 1,450 short tons annually) has been deleted from the producer list
because information now available indicates that little if any beryl mining
has been carried out in recent years.

TECHNOLOGY 
 The increasing concern with environmental pollution led to increased research
to develop more selective analytical methods. A routine method of analysis
for ultratrace concentrations of beryllium in particula-te matter collected
on air and water filters was described.~ 
 A report on the hydrolytic behavior of toxic metals, prepared by the Oak
Ridge National Laboratory,4 should assist in determining methods to remove
beryllium from water. 
 A process for making high strength beryllium by hot-pressing, extruding,
and upset-forging, was described.5 Isotropic compressive yield strengths
of greater than 100,000 pounds-per-square-inch were achieved. 
 A way to bypass -the traditional brittleness of beryllium by a technique
of diffusion-bonding thin sheets into a laminated plate was reported. The
resulting plate had better mechanical properties than the thin sheet from
which it was made, and properties substantially superior to sheet
