Objectives

The study of production and recovery processes of ferrous and non-ferrous metals by pyrometallurgy and hydrometallurgy.

Learning outcomes and competences

Transversal:

- Organize, interpret, evaluate and criticize data and results;

- Understand the information transmitted by oral presentations and written texts;

- Communicate scientific information and knowledge in a correct and clear way;

- Learning to learn;

- Building a positive attitude to Science;

- Develop teamwork and communication skills (oral and written).

Specific:

- Using the relationships between several concepts, and its application for solving specific questions.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Recommended prerequisites: concepts learnt on the course units of Chemistry I and II, Physical Chemistry, Phase Equilibrium Diagrams and Electrochemistry and Interfaces.

Program

1. Study of raw material used in the production of metallic materials, namely ore, sinter, pellets, pre-reduced, carbon and other fuels.

2. Iron works processes of pig iron production by using a blast furnace refining and casting processes. Furnace metallurgy and continuous casting.

3. Production of steel and other metals by using pre-reduced and scrap iron. The electric furnace.

4. Metallurgic processes of production of non-ferrous metals by igneous and refining processes taking into account materials reactivity.

5. Global diagram of hydrometallurgy; thermodynamic and kinetic aspects of leaching.

6. Leaching: methodologies and examples of processes.

7. Concentration and purification of solutions: application of ion-exchange resin, organic solvents and activated carbon.

8. Metal recovery from solutions: precipitation, cementation, electrolytic processes.

9. Recycling of scrap and metallurgical residues.

Teaching methods and learning activities

Theoretical and Practical lessons: oral presentation, supported by the exhibition of some transparencies, of basic concepts and some application examples, followed by a discussion and questioning period. The students should also solve some problems, proposed by the professor, related to the direct application of the concepts previously discussed. Seminars and/or field visits to industrial plants will be performed; participation will be included in the final grade.

Practical lessons: It will be developed, in group, a case study concerning a topic, previously chosen by the students and accepted by the professor. The results will be presented in class throughout the semester and the final delivery of the deliverables, which will result from all the work developed will be in the last week of classes.

Eligibility for exams

Students have to reach a passing grade in the practical component of the course unit.

Calculation formula of final grade

Final Grade = Practical component= 35% + Exam= 65% Students have to reach a minimum grade of 9.5 in the practical component and an 9.5 in the exam. Participation in the seminars/field visits is worth 5% of the final grade.

Examinations or Special Assignments

Not applicable

Special assessment (TE, DA, ...)

Special cases will be assessed in accordance to the rules applied to regular students in dates to be established.

Classification improvement

Students can improve the grade of the theoretical component by enrolling to an exam before the deadline. It will be a closed book written exam which is 2h:30min long.
