Topic Sub-topic
THEORY PROGRAMME

Introduction. Crushing. Primary, secondary and tertiary grinding. Machinery and equipment used. Criteria for selection and choice of size. Energy consumed.

Sorting minerals by grain size. Principles. Distribution curves. Types of sieving machines and screens. Calculation of capacity and performance. Methods of concentration: gravity separation, flowing film layer separation, separation by differential acceleration or dense medium separation.

High- and low-intensity magnetic separation methods, dry and wet. Electrostatic separation methods. Types of separator, particularly high-tension versions.

Concentration through flotation. Physical and chemical principles of the process. Reagents, equipment and cells used in the process.

Solid-liquid separation. Thickening, clarifying and filtering. Equipment used, particularly Dorr tanks, lamellas (inclined plate settlers), vacuum filters and filter presses. Treatment of acid mine tailings.

Typical schematics for mineral treatment plants. Mineralogical environmental technology.



PROGRAMME OF PRACTICAL AND LABORATORY CLASSES

1. Crushing, grinding and milling in jaw crushers and hammer-and-ball mills.

2. Carrying out grain-size analyses and producing charts of granulometric curves.

3. Practical problems on the selection and sizing of crushing and sorting equipment.

4. Calculating performance in grain-size separation.

5. Practice in separation techniques using one or more of the following pieces of equipment: shaker table, magnetic separator, flotation cell, and others.

6. Practical sessions on the design of mineral installations using USIM PAC process simulation and optimization software, so as to improve treatment plant efficiency.

Personalised or group attention at the teacher's discretion, depending on the type and content of the subject in question.

A timetable for tutorials will be set.

Assessment
  Description Qualification
Assignments Resolution of problems and/or work to be carried out by the student. Attendance at seminars will also be assessed. 10%
Laboratory practicals Assessment test of the practical work carried out in the laboratory. Practical work with USIM PAC software. 5%
Field work/trips Presentation of a report on the visit to the mineral processing plant. 5%
Extended-answer tests Written exam, theoretical and practical part.
 80%
 
Other comments and second call

In order to pass in the first call (course evaluation), it is necessary to obtain a score equal to or higher than 5 points in the written exam, as well as in the laboratory practicals, assignments and visit to a company.

If the above conditions are met, the final mark will be obtained by adding the marks obtained in the written exam, multiplied by its weighting coefficient of 0.80; the marks obtained in the Seminar, Work and Laboratory Practicals assessments, each of them multiplied by the weighting coefficients described above.

In case of obtaining a score lower than 5 points in the written exam, the final score will be the one obtained in the written exam.

In the 2nd Round, only the written exam will be taken, including the material taught in class and practical work, as well as the visits.
