A copper mine located at Alentejo near Mertola. Owned by Billiton. Closed in 1966.
Located 15 km north of Mértola.


A Mina de São Domingos (Mértola, Baixo Alentejo, Portugal): actividade industrial moderna (1854-1966).
Rui Jorge Narciso Palma Guita (Licenciado em Antropologia Social pelo Instituto Superior de Ciências do Trabalho e da Empresa (Lisboa, 1988), mestre em Museologia Social pela Universidade Lusófona de Humanidades e Tecnologia (Lisboa, 2006); coordenador da Fundação Serrão Martins)

- Resumo
A Mina de São Domingos faz parte da província metalogénica de classe mundial conhecida como Faixa Piritosa Ibérica (FPI), uma região com 30 a 60 km de largura e 240 km de comprimento que se estende desde o rio Sado e Setúbal (Portugal) até ao rio Guadalquivir e Sevilha (Espanha) e se constitui como uma fonte decisiva de metais básicos (Cu, Zn, Pb, Sn, Ag, Au, Fe, Co, Cd, etc.) e de outros elementos como o enxofre (S). O depósito pirítico de São Domingos foi explorado em diversos períodos históricos, nomeadamente: durante vários séculos do primeiro milénio a.C. (período Oriental), durante o período que mediou entre o ano 14 a.C. e o ano de 395 d.C. (período romano), durante o período islâmico e durante o período delimitado pelos anos de 1854 e 1966 (período moderno) …

- Enquadramento Geológico
A origem do depósito pirítico de São Domingos é em tudo semelhante à dos demais depósitos de polisulfuretos metálicos da Faixa Piritosa Ibérica (FPI): há cerca de 360 milhões de anos a actividade hidrotermal submarina trouxe da profundidade geológica em fusão massas de água a muito elevadas temperatura (300 a 400 ºC) e pressão, capazes de arrastar em solução grandes quantidades de sulfuretos dissolvidos (principalmente o sulfureto de ferro ou pirite – FeS2, com quantidades menores de cobre, zinco, chumbo, estanho, arsénio, prata, ouro, cobalto, cádmio, etc.) que, ao atingirem a superfície do fundo marinho, libertam por precipitação os sulfuretos que não podem continuar dissolvidos num líquido muito mais frio e menos denso. As zonas dos fundos marinhos onde ocorre este tipo de nascente termal metalogénica tornam-se, com o acumular de precipitados, espessas massas mineralizadas ricas nos metais referidos. A evolução geológica haveria ainda de criar a zona Sul de Portugal e fazer emergir a Faixa Piritosa Ibérica do mar cheio de vulcões em que se formou mas os depósitos de pirite de Portugal e Espanha estavam já formados e à espera dos primeiros mineiros. Cerca de 1700 milhões de toneladas geradas, cerca de metade já erodida ou já extraída, a Espanha cabem 90% das ocorrências e a Portugal 10%. Dentro dos parâmetros da FPI, o depósito da Mina de São Domingos é de tamanho médio: cerca de 27 milhões de toneladas de pirite cuprífera com teor médio de 1,25% de cobre (Cu), 1% de chumbo (Pb), 2% de zinco (Zn), 45-48% de enxofre (S)3, além de ferro (Fe), e arsénio (As). De forma diversa da maior parte da centena de depósitos minerais da FPI, que comportam quase sempre duas ou mais massas distintas, o depósito da Mina de São Domingos revelou ser uma única massa de pirite, distribuída entre a superfície e os 420m de profundidade.
