Litargirio y plomo (± plata) en la mina La Argentina, Córdoba: Aporte de la mineralogía a la metalurgia extractiva de mediados del siglo XIX
Mining and metallurgical activities at El Guaico and La Argentina mining districts, northwest of Córdoba province, began at the dawning of the 19th century; however, mining records in the province date back to the end of the 16th century.

La actividad minero-metalúrgica en los distritos mineros El Guaico y La Argentina, en el noroeste de la provincia de Córdoba, comenzó a principios del siglo XIX; sin embargo, los antecedentes de la minería en la provincia se remontan a finales del siglo XVI. En la actualidad sobreviven vestigios de lo que otrora fue un foco de beneficio socio-económico para la región, como establecimientos abandonados, hornos de fundición en ruinas y voluminosas escombreras enmascaradas por la vegetación. En 2018 se halló material digno de estudio en escombreras contiguas a las ruinas del horno de fundición de mina La Argentina. Estudios por difracción de rayos X y espectroscopía de energía dispersiva de rayos X permitieron su identificación como litargirio (PbO) con inclusiones de plomo argentífero (Pb ± Ag). Si bien la muestra presentaba indicios texturales de material artificial, el estudio fue motivado debido a que ambos compuestos químicos pueden también formarse en la naturaleza conformado especies minerales homónimas, precisamente en la zona de oxidación de esta tipología de yacimiento en varias localidades mundiales. Su caracterización como producto metalúrgico derivado del beneficio de menas de plata de La Argentina permitió ahondar en el escaso conocimiento del pasado metalúrgico de la región noroeste de la provincia de Córdoba y confirmar datos previos de la existencia y origen del litargirio, publicados a fines de 1800.
