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
Students have to be present in at least 75% of the theoretical-practical and laboratorial practical class taughtand reach minimum grade of 7 out of 20 in continuos assessement
Calculation formula of final grade
AC - Continuous assessment - 50%
FA - Final exam - 50%
The continuous assessement will be calculated using the formula:
AC = 0,15*laboratory reports + 0,05* attendance + 0,30* assessment test
Final Grade (NF) will be calculated using the formula:
NF =0,5*AC+0,5*NT
To complete the course unit, students have to reach a minimum grade of 7 out of 20 in Final Exam.
Examinations or Special Assignments
For the students that are not available to realize continuous evaluation, final grade will be equal to the final exame grade.
Internship work/project
Not applicable.
Special assessment (TE, DA, ...)
In accordance with UP/FEUP rules
Classification improvement
Students may only improve their grades by attending a final exam. Students may not improve the grade of the continuous assessment component.
