Mineral Processing and Sustainable Exploration and Mining

Objectives

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.

Evaluation method

The assessment is carried out by two tests of two hours each in the class period, or final exam, plus the answers to questionnaires provided in each class and delivered at the end of the class. The tests account for 50% of the final grade (25% each), and the remaining 50% are the class-by-class questionnaires (continuous assessment). The minimum test score is 8 out of 20.
