Course content

The course shall give the student an ability to work with production of inorganic raw materials for metallurgical and chemical industry as well as for civil engineering. Traditionally the source of the raw materials have been primary recourses (ore and mineral desposits), but the importance of secondary raw materials like scrap and other types of waste is increasing. The subject is divided into three parts: Particulate technology which gives knowledge of matters like particle size and shape, the behaviour of particles in fluids, comminution, sampling and transport. Separation processes relating to differences in particle size, surface properties, magnetic properties, optical properties, electric properties and specific weigth. Processing in practice. The aim is to give an understanding of how unit operations are tied together to produce raw materials for other industries from the various fields available. A number of examples are given from existing processes.

Learning outcome

The couse is intended to give students a background to lead the production of inorganic raw materials for metallurgical and chemical processes and the construction industry. The students must therefore have knowledge af the most usual unit processes and the physics and chemistry behind them and to be able on that basis to arrive at well founded process flowsheets. Callculations performed during the laboratory work have to be mastered.

Learning methods and activities

Lectures. Laboratory exercises. Excursion. The exam can be changed from written to oral at the postponed exams (continuation exam).

Compulsory assignments

• Exercises
• Excursion

Recommended previous knowledge

Good knowledge of chemistry, mechanics and physics. One should also be motivated to learn the names of the most common minerals if not known previously.
