Mineral Processing and Sustainable Exploration and Mining
Provide students technical and practical concepts of mining and processing of ores, with emphasis on metallic ores and special sands, namely, choosing the most appropriate techniques, equipment’s and procedures, and environmental impacts. Students will be able to integrate team-works concerning the execution of technical mining projects, as well as to integrate the teams of monitoring and optimization of processes and preparation of environmental impact studies. Learn mining exploration techniques and methodologies. Learn the steps and activities in an exploration and mining project. Mining project development, environmental impact assessment and licensing of exploration and mining projects.

Teaching is provided by theoretical sessions and practical lab sessions where it is presented technical concepts whenever possible with documented examples and solves quantitative problems. Two field trips are planned in each edition, one of special sands and another one of metallic ores. All information and presentations are available on the Web (CLIP). Real problems related with exploration and prospecting methods, distinct mining examples and its related technologies and specific equipment will be presented. Examples of EIA and IA Proceeding for exploration and mining projects will be presented and discussed.
The evaluation is of the continuous type, in each session / week a questionnaire and / or problems are proposed that must be delivered until the end of that week. The works proposed each week have the same weighting in the final grade. This questionnaire / problems can be replaced by a final exam.
