Abstract

Crystalline stibnite occurrences in the Republic of Macedonia in several antimony deposits such
as Allchar, Lojane and Krstov dol. The best stibnite crystals can be found in the central parts of the
Allchar mine. Crystals of stibnite are thick to thin elongated prisms with vertical striations, lead gray
color and high metallic lusters. Stibnite also occurs in columnar, granular, blended and compact habits.
Cleavage is perfect on {010} and imperfect on {100},{110}. The density determined by pycnometer is
4.62 g/cm3
. Hardness is 2. The concentration of the oxides is: Sb:70,912-71,155%, S:27,166-28,166%.
The following trace elements were also detected: As, Tl, V, Se, Ba, Ag, Cr, W, P. The unit cell
parameters obtained using the main reflection lines of X-ray diffraction are: a = 11.24 Å, b = 3.84 Å, c
= 11.34 Å, V = 490.43 Å3
, Z: 4.
