is a rare member of the Galena Group of minerals that also
Clausthalite and Galena. Altaite
is a lead telluride mineral that is opaque with metallic
luster and color of tin-white
with yellowish tint that may tarnish to bronze. Altaite
is often found with Galena which it shares the same
structure and other properties. Altaite has a greater
density than Galena however. The two minerals are found together in sulfide vein ore bodies.
Altaite is also associated with
and several Gold and Silver sulfides and tellurides.
