Environmental management and life cycle approaches in the Mexican mining industry

Mexico ranks among the I I major producer countries of minerals worldwide; its open pit and underground systems arc 500 years old. This paper presents an overview of the Mexican mining industry from technological development, historical and economic perspectives. The efforts made by mining companies to address issues or environmental management and sustainable development expressed in national and international frameworks, as well as the Mexican environmental regulatory framework for the mining sector, are analyzed. Since, among others, life cycle assessment (LCA) has been recognized as a key topic to promote sustainable development in the Latin American and Caribbean region, this paper also examines the application of LCA in mining. Two life cycle approaches are presented: a national life cycle inventory for base metals, and an integral life cycle model for the management of mining processes. (c) 2005 Elsevier Ltd.
