The document discusses increasing sustainability in mining through case studies from Brazil and visions for Chile. It summarizes two case studies: (1) environmental liability management of 350 mining sites to assess costs and create remediation plans, and (2) a life cycle analysis of iron mining and processing to compute sustainability indexes. The document concludes that data collection, consistency, detailing, computational models, and critical analysis are key lessons for using tools like life cycle analysis to improve eco-efficiency and sustainability in the mining industry.
