APATITES OF SPAIN. 
The only other apatite deposits which have yet become of commer- 
cial importance are in Spain. At Malpartida de Caceres are the mines 
of Senor Grappin. The mineral occurs in granite, and about six thousand 
tons annually have been shipped in good years. Considerable deposits 
of apatite are found at Zarza la Mayor, and at Ceclavin, in the district 
of Alcantara, near the Portuguese frontier, and about twenty miles 
from the Tagus. Crystalline apatite is also found in the volcanic rocks 
at Jumilla, in the province of Murcia, which averages 86 per cent, phos- 
phate of lime. 1 It is also found in the provinces of Alemtejo and Za- 
mora. 2 The Jumilla apatite is often of the yellowish-green variety, 
known as asparagus stone or Spargel stein. 
The Spanish apatite deposits are limited in quantity, compared with 
the phosphorite deposits of that couutry, and they have never produced 
more than a very few thousand tons annually. At present, on account 
of the disturbe d political condition of the country, no apatite is ex- 
ported. 
A description of the other Spanish deposits is given under the subject 
of phosphorites.
