Sulfides: antimonnickel
Diagnostic Card.
Ni Sb
Crystal system hexagonal
5.5 Hardness
Specific gravity 7,5-8,2
Colour red
The color of the powder is reddish-brown, black
shine metal
Submitted by rare individuals hexagonal crystalline flattened shape. More common scattered branching education and small dense masses. Colour copper-colored, with a sheen of purple tones.
Origin.
Antimonnickel occurs in association with native silver, silver minerals and silver-arsenic minerals.
Deposits and application.
Beautiful patterns in the form of prismatic crystals and small clusters of massive copper-red color found in the mines of Sar-Rabus in Sardinia (Monte Nar-ba Masaloni, Giovanni Bon).
Antimonnickel occurs together with sphalerite, ulmanitom, millerite, galena. Less interesting, but more numerous samples breytgauptita mined in Andreasberg in the Harz (Germany), and Cobalt, Ontario (Canada). Antimonnickel has little practical application.
