Course Objective

1.Describe the unit operations in mineral processing such as crushing, grinding, laboratory and industrial screening, classification and concentration techniques. Preliminary treatment processes such as drying, calcination, roasting and agglomeration. Direct and indirect reduction. Recycling of scrap. 2.Do calculations related to the thermodynamics and kinetics of pretreatment processes. 3.Design simple flowsheets using various unit operations and pretreatment processes for the concentration and preparation of ores for the extraction of metals.

Course Content

Drying; principles of drying equipment. Calcination; principles of calcination, calcination furnaces. Roasting; thermochemistry, types of roasting, roasting furnaces and product control. Agglomeration processes; sintering, pelletizing, nodulizing, and briquetting. Theory of sintering and pelletizing. Description of industrial agglomeration processes. Solid state reduction processes; direct and indirect reduction.

Learning Outcomes

Students choose proper unit operations, pretreatment processes and apply their knowledge of mass balance, thermodynamics and kinetics to the specific extractive metallurgy related topics. The course is also designed to cover the methods for treating residues of metallurgical plants and recycled raw materials for environmental and economic reasons.
