Metallurgy of Lead, Zinc, Cadmium
Description: Theoretical and practical fundamentals of the production of lead, zinc and cadmium, modern and advanced technologies for their production and prospects for the development of the industry are presented. The raw material base of zinc, lead, cadmium and technological schemes for processing ores and concentrates of these metals have been determined. Metallurgical calculations of special pyrometallurgical operations (roasting, smelting, refining) and hydrometallurgical processes (leaching and separation of metals and their satellites from solutions) that determine metallurgical technologies for the production of lead, zinc and cadmium are presented.

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.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | task 1 Alkaline refining of lead from tin, arsenic and antimony | 0-100 |
| task 2 Coursework. Metallurgical calculation of the processes of roasting, smelting and refining of metals (Pb, Zn). | ||
| Test PK 1 | ||
| 2 rating | Task 3 Obtaining cadmium sponges by cementation, calculation according to equations of chemical reactions. | 0-100 |
| Task 4 Crystallization from Pb-Sn-Cd melt (graph-analytical calculation). | ||
| Test PK 2 | ||
| Total control | Exam | 0-100 |
The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory | |
| Obtaining higher education knowledge in the metallurgy of lead, zinc and cadmium | The theoretical content of the course was mastered completely without errors with the maximum number of points | The theoretical content of the course has been fully mastered, without gaps, some practical skills in working with the mastered material have not been sufficiently developed, all the educational tasks provided for in the training program have been completed, the quality of none of them has been assessed with a minimum number of points, some types of tasks have been completed with error | The theoretical content of the course has been partially mastered, but the gaps are not significant, the necessary practical skills in working with the material mastered have been basically formed, most of the educational tasks provided for in the training program have been completed, some of the completed tasks may contain errors | The theoretical content of the course was mastered completely without errors with the maximum number of points |
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:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
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:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
