Presentazione
The aim of this course is to offer an outline of the technologies employed in the processing of raw materials. By raw materials we mean solid georesources with a market value destined for use in industry. Knowledge of the properties of solids shall be the starting point for the identification of the best physical and mechanical process techniques to adopt to obtain a raw material. The operations that shall be considered include solid separation and treatment methodologies based on the physical and mechanical properties of the materials. Some of the most important examples of mineral processing for the production of primary materials shall be examined, and at the end of the course the students shall be able to design a treatment plant on the basis of the knowledge acquired during the course.
Risultati di apprendimento attesi
The students should develop the ability to identify the best methodologies to apply in order to obtain a free substance that can be used as a raw material from natural resources. The student shall have the possibility of testing the physical and mechanical properties of some minerals/rocks in the laboratory. At the end of the course, the students shall be able to evaluate which separation methodologies can be applied to obtain a free grain, that is, how to obtain the free raw material from the additional components to which it is connected in nature. The analysis and observation capacities acquired over the three year degree course shall be necessary for this purpose.
Prerequisiti / Conoscenze pregresse
The students should have knowledge of the fundamentals of physics, chemistry and structural mechanics. They should also be capable of carrying out preliminary evaluations and make general process designs to obtain raw and secondary materials.

 Flotation
 Other separation methods.
 Examples of mineral processing plants: minerals for the glass, ceramic and refractory industries, limes and cement, aggregates and ornamental stones.
Organizzazione dell'insegnamento
In the lecture rooms: theory lectures.
Practical lessons shall be carried out in the laboratory on: sampling, particle size analyses, differential comminution, magnetic separation, densimetric separationin fluid medium, flotation, mechanical strength of rock samples, determination of the physical properties of stone materials.
Visits to process plants are foreseen.
The last part of the course will be devoted to the design of a process plant that will be presented during the final lesson.
Testi richiesti o raccomandati: letture, dispense, altro materiale didattico
Notes shall be made available by the lecturer.

Criteri, regole e procedure per l'esame
The final evaluation is the weighted average of the following three phases:
1) the project of treatment will be presented by each group on the last day of the lesson, to the colleagues of the course and to the experts called by the teacher (time for each presentation: 15 minutes) . Its rating will weigh as much as 50% of the final vote.
2) Each student must deliver at least two days before the final examination a report on one of the didactic visits and a second report on one of the laboratory exercises carried out. The vote attributed to the reports will weigh for a quarter of the final vote.
3) The oral examination, which will weigh for the last quarter, will consist of a question related to the subjects of the course not addressed in the project and in the reports.
