Basic mineral processing

Description: It contains theoretical bases of mineral processing (sorting, gravitational and flotation enrichment, magnetic and electric separation, chemical methods of enrichment). The enrichment equipment and the principle of its operation are considered. The practice of mineral processing is highlighted. Designed for students of enrichment and metallurgical specialties.

Learning outcome: learning skills or learning abilities

• Successful passing of exams

Teaching methods

Interactive lectures, the use of electronic educational materials

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
