Course Workload:

Component: University component

Cycle: Base disciplines

Goal

• The purpose of this course is to master the theoretical foundations of mineral processing processes, principles of operation of processing equipment, technological schemes of mineral processing.

Objective

• Consolidation of the obtained theoretical knowledge, on the basis of which it is possible to carry out the selection, justification and calculation of technological schemes for mineral enrichment.

Learning outcome: knowledge and understanding

• To know the main dividing signs, on the basis of which the separation of minerals from waste rock occurs, and hence the choice of the method of mineral enrichment.

Learning outcome: applying knowledge and understanding

• Be able to choose and calculate the technological scheme of enrichment and equipment for the enrichment of minerals.

Learning outcome: formation of judgments

• Possess the skills of active use of reference literature in the study of theoretical issues of mineral enrichment.

Learning outcome: communicative abilities

• The ability to use the acquired theoretical knowledge in practical activities.

Learning outcome: learning skills or learning abilities

• Successful passing of exams.

Teaching methods

Interactive lectures, the use of electronic 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:
