  915Talc and Pyrophyllite 
By Robert A. Clifton1 
 Increasing demand for talc on the world market led to a 10% increase in
total domestic production of talc and pyrophyllite. Production of talc increased,
while that of pyrophyllite declined. The value of crude talc and pyrophyllite
produced increased 32% and averaged $10.86 per ton. 
 Table 1 shows a 24% increase in total sales of crude and processed talc
and pyrophyllite and a 54% increase in value. Apparent domestic consumption
increased minimally over that of 1976, but exports increased 52% in tonnage
and 1% in value. 
 Cyprus Industrial Minerals Co. announced plans to double the capacity of
its 
Ghent, Belgium, talc-processing facility. 
 A new organization, the Scientific and Technical Association of the European
Talc Industry (EUROTALC), was founded on May 3, 1977. The association membership
is open to any company mining its own talc and grinding it in Europe. The
six charter members established EUROTALC's headquarters at 22 Rue du Musee,
1000 Brussels, Belgium. One of the first acts of the association was to initiate
a physiological and epidermoidal survey among European talc workers. This
survey follows the association's announced aim of encouraging fundamental
research for the promotion of the
