Abstract

The Spanish-Portuguese Pyrite Belt covers a large area in the SW part of the Iberian Peninsula. Known reserves of massive pyrite and cupreous stockwork ore exceed 1000 million tons.

The stratiform sulphide deposits and accompanying manganese mineralization are of synsedimentatry-exhalative origin and occur in a Lower Carboniferous, geosynclinal, volcanic-sedimentary rock sequence, strongly folded during the Hercynian Orogeny. Epigenetic stockwork ores are in close relationship with volcanism and often represent the feeder channels of the massive sulphide sedi-ments.

Most important ore types mined are massive “crude” pyrites, lead-zinc-rich “complex” pyrites, high-copper “banded” ores, copper-rich stockwork ores, disseminated “porphyry”-type copper ores and gold-silver-rich gossans. The main active mines are described and beneficiation of these ores is discussed.
