Teaching method

The teaching method adopted includes the combination of lectures and exercises under the reflected light microscope for the acquisition of the basic principles of ore minerals. During the lectures will also be used films related of the metals and alloys and mineral pigments applied in Cultural Heritage.

 

Attendance

Attendance is not compulsory, but assiduous participation by the student is recommended, especially in laboratory exercises.

 

Evaluation

The assessment of the actual achievement by the student is through an oral test with open stimulus and open answer, during which the student presents a project on topics agreed with the teacher. To pass the exam the student must obtain a grade of not less than 18/30.

The determination of the final grade takes into account the logic followed by the student in answering the questions, the adequacy of the answer in relation to the skills that the student assumes he/she has acquired and the use of an appropriate language. Furthermore, he must be able to apply the acquired knowledge in a competent and reflective way.

The student must demonstrate that he/she has acquired a sufficient knowledge have acquired a sufficient knowledge of the main forms of degradation of metals, their alloys and pigments.

To achieve a score of 30/30 cum laude, the student must instead demonstrate to have acquired an excellent knowledge of all the topics covered during the course, have studied the focal points in depth and be able to link these topics in a coherent and logical way.

PROCESSI METALLOGENETICI MINERALI E ROCCE DI INTERESSE ECONOMICO 1044642 2021/2022

Contents

In the first part of the course (24 hours, 3 CFU) we will discuss the contents related to the formation processes of ore deposits, depositional classifications and genetic models. Examples of the main types of ore deposits included in the relative geodynamic context will be illustrated.

In the second part of the course (16 hours, 2 CFU) we will discuss the contents related to industrial rocks and minerals, to the various types of quarries and to the main techniques of exploitation and processing of materials. The main environmental problems of mining activities will also be addressed.

The third part of the course (12 hours, 1 CFU) will be devoted to laboratory exercises for the recognition in reflected light of the main metallic minerals.

Ore-forming processes. Origin and main characteristics of the mineralizing fluids. Classifications of ore deposits and genetic models. Examples of ore deposits related to intracratonic magmatism; ore deposits related to mantle basic magmatism; deposits related to alkaline magmatism; deposits related to melting of metasomatized sucontinental lithospheric mantle (SCLM); ore deposits related to intracontinental rifting; ore deposits related to divergent margin tectonics; ore deposits related to convergent margin tectonics; sediment-hosted deposits. Economic importance and industrial application of base metals (Pb, Cu, Zn, Cd, etc.), alkaline metals (Be, Cs, etc.) precious metals (Au, Ag, Pt, PGE, etc.), transition metals (Nb, Ta, Mo, W, etc.) and REE.

The use of stones. Physical-mechanical properties of stones. Evaluation of the quality of stones. Alteration. Use of industrial stones. Laboratory characterization of stones by optical microscopy, X-ray diffraction, SEM, FTIR, chemical analysis.

Laboratory exercises for the recognition in reflected light of the main metallic minerals.

 

Teaching method

Evaluation

The assessment of the actual achievement by the student is through an oral test with open stimulus and open answer. The determination of the final grade takes into account the logic followed by the student in answering the questions, the adequacy of the answer in relation to the skills that the student assumes he has acquired and the use of an appropriate language.

The student must demonstrate that he has acquired a basic knowledge of the topics related to the relationships between mineral deposits and their geodynamic environments, as well as to the main techniques of quarrying and processing of materials of economic interest. Furthermore, he must be able to apply the acquired knowledge in a competent and reflective way.

In order to obtain the maximum score, the student must demonstrate excellent knowledge of all the subjects dealt with in the course, have studied the focal points in depth and be able to link these topics in a coherent and logical way.
