A newer commercial use for pyrite is as the cathode material in Energizer brand non-rechargeable lithium metal batteries. [20] Pyrite is a semiconductor material with a band gap of 0.95 eV. [21] Pure pyrite is naturally n-type, in both crystal and thin-film forms, potentially due to sulfur vacancies in the pyrite crystal structure acting as n ...
A considerable part of the pyrite production began to be destined to the Chemical Park of Huelva, where several industrial plants operated, which were abundantly nourished by pyrites. Due to this circumstance, the RENFE company set up a link that connected the Gibraleón-Ayamonte line with the Tharsis railroad and reached the Corrales station .
It is a fact that the vast majority of mining operations in the Iberian Pyrite Belt remained inactive since the end of the Roman period. It was during the 19th century when the deposits of the Alosno mountains were visited again by mining engineers such as Fausto Elhuyar , Joaquín Ezquerra , Agustín Martínez Alcíbar or Luciano Escobar.

The most important economic minerals are tennantite‐tetrahedrite (containing most of the silver), sphalerite, galena, and chalcopyrite. Silver is also found in pyrargyrite, proustite, polybasite, and pearceite. In the central copper core of the Huarón deposit, enargite occurs. [4] Main gangue minerals are pyrite, quartz, rhodochrosite, and ...
The mine was due to be shut down in 2019, but due to an increase in demand for pyrite from Yara in Siilinjärvi, mining was extended to continue approximately 14 more months. Pyrite is a byproduct of copper and zinc mining. As of now, mining is going to be continued until spring 2021 [needs update]. Above-ground refining will continue until ...
Ionometallurgy makes use of non-aqueous ionic solvents such ionic liquids (ILs) and deep eutectic solvents (DESs), which allows the development of closed-loop flow sheet to effectively recover metals by, for instance, integrating the metallurgical unit operations of leaching and electrowinning.

Corta Atalaya is a mine in western part of the Iberian Pyrite Belt. It is part of a zone of volcanogenic massive sulfide ore deposits of Silurian to Carboniferous age which has produced significant copper, zinc, lead, gold and silver. [7] [8]
