Technological processes and devices

Description: The discipline "Technological processes and devices" contains theoretical and practical material on the physical and chemical foundations of technologies for obtaining metals from ore and secondary raw materials. It contains information about the composition of the feedstock, methods of its charge preparation, hydro- and pyrometallurgical processing methods. The discipline includes the basic provisions of the higher school on the use of the basic laws of hydromechanics, mass transfer and heat transfer in the design and research of metallurgical processes, including basic and auxiliary equipment.

Teaching methods

Metallurgy

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:
