Copper and mispickel are mined only in small quantities.
Mines of iron, manganese, and especially of mispickel, are worked, and there are stone-quarries and productive saltmarshes.
MISPICKEL, a mineral consisting of iron sulpharsenide, FeAsS; it contains 40% of arsenic, and is of importance as an ore of this element.
Arsenikkies) : mispickel is an old name of German origin, and in the form Mistpuckel was used by G.
Mispickel occurs in metalliferous veins with ores of tin, copper, silver, &c. It is occasionally found as embedded crystals, for example, in serpentine at Reichenstein, Silesia.
Mispickel is the principal source of arsenious oxide or the "white arsenic" of commerce (see Arsenic).
Danaite is a cobaltiferous variety of mispickel, containing up to 9% of cobalt replacing iron; it was first noticed by J.
The crystals are isomorphous with mispickel, but only rarely are they distinctly developed and simple (fig.).
