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, while by secondary materials we mean those materials that are recovered from waste. 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 or a secondary materal. 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 and solid waste processing for the production of primary and secondary 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.

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 both from natural resources and from waste. The student shall have the possibility of testing the physical and mechanical properties of some minerals/rocks and some recyclable waste substances in the laboratory and by means of different separation methodologies to reach a valuable yeld of the desired substance. At the end of the course, the students shall be able to plan a process treatment obtaining the free raw material from the additional components to which it is connected in nature if dealing with minerals, or in the commercial product, if dealing with wastes. The analysis and observation capacities acquired over the three year degree course shall be necessary for this purpose.
The students should develop the ability to: identify the properties of a unknown material (both mineral or waste) plan the steps needed to reach the desired products through a physical-mechanical treatment process verify the validity of the results of tests carried out by them amd by other laboratories identify the discrepancies between the expected result and the one obtained and be able to trace their causes
The students should have knowledge of the fundamentals of physics, chemistry, statistics and material sciences. They should also be capable of carrying out preliminary evaluations and make general process designs to obtain raw and secondary materials.

(10 h)
The course is organized in lectures, exercise-classes, visits to process plants . Lectures are devoted to the presentation of the course topics, in their theoretical aspects and applicative examples. Exercises classes shall be carried out in the Solid Processing Lab where students, in workgroups, will apply the treatment processes learned in the theoretical lessons, on samples of different materials, with the assistance of the instructor. The exercises will be 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 industrial plants are planned in order to allow students to understand the real complexity of a treatment plant. The last part of the course will be devoted to the design of a process plant that will be presented during the final lesson.
The course is organized as in the following: - in the lecture rooms, theory lectures (33 h); - practical exercises in laboratory (27 h); - visits to different industrial plants (10 h); - design of a process plant that will be presented during the final lesson (the last 10 h). Lectures are devoted to the presentation of the course topics, in their theoretical aspects and applicative examples.

Modalità di esame: Prova orale obbligatoria; Elaborato scritto individuale; Elaborato progettuale in gruppo;
Exam: Compulsory oral exam; Individual essay; Group project;
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.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

The exam is aimed at verifying that the student has acquired the expected learning outcomes relating to the ability to identify the best techniques for the treatment of raw and secondary materials. For this purpose, students will present a mineral or secondary material treatment project in which they will have to indicate and justify the different steps of the process and the machines chosen. Reports are also required on the labworks carried out and on the field trips, which will allow the student to show the level of in-depth study achieved with respect to the topics covered 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 oral examination a report on one of the didactic visits and a second report on one of the laboratory exercises carried out.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
