Abstract(s)
A indústria mineira está habitualmente associada a impactes ambientais negativos sobre o meio
ambiente. Os resíduos resultantes da atividade mineira, escombro e rejeitados, sendo geradores
potenciais de águas ácidas, constituem um risco ambiental elevado, sendo um dos principais
focos de contaminação dos solos e águas. Décadas de atividade mineira conduziram à geração de
um passivo ambiental muito significativo, uma vez que até o final da década de 80 não existia em
Portugal um adequado processo de recuperação ambiental das áreas afetadas e legislação
aplicável. A consciência sobre os possíveis impactes ambientais tem aumentado ao longo das
últimas décadas, levando as empresas a adotar práticas sustentáveis. Prevenir, mitigar e reparar
os impactes negativos da exploração mineira sobre o ambiente são fundamentais, não só no
fecho da mina, mas ao longo de todas as fases do ciclo de vida da mina. Na Somincor, são vários
os exemplos de boas práticas e medidas de prevenção e mitigação utilizadas para evitar que
qualquer impacte ambiental seja irrecuperável. A Boliden é membro do ICMM – Conselho
Internacional de Mineração e Metais, organização internacional focada no desenvolvimento
sustentável das atividades mineiras e tem como missão contribuir para interromper e reverter a
perda de biodiversidade.
The mining industry is usually associated with negative environmental impacts. The waste resulting from mining activities, including waste rock and tailings, which can be potential generators of acidic waters, constitutes a significant environmental risk and is one of the primary sources of soil and water contamination. Decades of mining activity have generated significant environmental liabilities, as there was no adequate environmental recovery process for affected areas and no applicable legislation in Portugal until the end of the 1980s. Awareness of potential environmental impacts has increased over the past few decades, prompting companies to adopt sustainable practices. Preventing, mitigating, and repairing the adverse environmental effects of mining are fundamental, not only at mine closure but throughout all phases of the mine's life cycle. At Somincor, several examples of good practices and prevention and mitigation measures are employed to prevent any irreparable environmental impact. Boliden is a member of the ICMM - International Council on Mining and Metals, an international organisation focused on the sustainable development of mining activities and whose mission is to contribute to halting and reversing the loss of biodiversity.
