Objectives

-Knowledge:Knowledge of basic sciences (chemistry, physics) applied to the characterization of particulate systems; - Comprehension: Recognize, describe and identify the unit operations involved in concentration of ore. - Application: To discriminate the field of application of different technologies: to select the most appropriate technology for a particular case. - Analysis: To calculate the materials balance in steady-state using analytical, numerical and graphical methods for each unit operation. - Synthesis: Create and organize coherent process flowsheets for each unit operation and for the process as a whole. Evaluation: Compare different process alternatives

Eligibility for exams

To obtain attendance students may not exceed the maximum number of missed classes, complying with school attendance rules. (attendance registration will be done in every  class).

Calculation formula of final grade

Final grade = 0.2* Grade of the continuous assessment component + 0.8* Grade of the final assessment component

The assessment is base on two components: 
Continuous assessment component: 20% of the final grade, being 15% of that mark based on the laboratory component,  5% ofparticipation in classes.
Final assessment component: 80% - Final exam. 

To complete the course unit, students have to reach a minimum grade of 7 out of 20 in the Final assessment component.
