Course Synopsis

This course provides some basic principles of fluid mechanics. Fluid mechanics may be defined as the study of behaviour of fluids under the influence, of forces. These forces are stresses and velocities that occur in a Newtonian and non Newtonian fluid in motion or at rest. The course is thought under two broad topics Viz; fluid statics and fluid dynamics. Fluid statics is the study of forces which keeps fluids in static equilibrium while fluid dynamics deals with the motion of fluids and forces which keep them in motion. Fluid dynamics can be subdivided into hydrodynamics and gas dynamics. Hydrodynamics is the study of fluid flows where there are no density changes. The flow of liquids falls into this category mainly but it also includes the flow of gases at low speeds. A subdivision of hydrodynamics is called hydraulics, which is the study of flow where density changes occur such as high speed gases flow through conduits or over solid surfaces. Aerodynamics is the study of gas flow which combines both low speed and high speed flows. The course will consist of theory and laboratory practical experiments. It is believed that the course will cover both B.Eng and Bsc degree levels for most universities in the field of fluid mechanics. It could also serve as an introductory course for masters degree programme in fluid engineering for most universities all over the world.

Course Synopsis

The course, mineral processing technology 1, is the first 300L course and the gate way to the profession. The first objective is to acquit the students with the various technical terms used in the solid mineral industry especially mineral processing and mineralogy. It underscores the importance of value addition to solid minerals for techno-economic advancement in any nation. It discusses the interdependence of the various disciplines involved in winning of minerals and production of metals/alloys: from geology and mining engineering to extractive metallurgical engineering en route mineral processing technology. The course encompasses introduction to mineralogy, application of mineralogy to mineral processing technology, communition and communition theory, particle size analyses and classification. The major issue involved in mineral processing technology is processing techniques: physical, physico-chemical and to some extent some chemical processes. Physical processes entails gravity separating methods such as calabashing, shaking tabling, air-floating, sluice boxing, spiralling and jigging. The physico-chemical aspect has to do with froth floatation-principle, floatation cell, reagents and application and coal-goal agglomeration. The theoretical aspect of this first aspect of mineral processing technology is capped with flow-sheet development and material balance. As a practical course, the objective is to impart necessary skills on basic techniques for identification of minerals based on their properties, the use of mineral processing equipment for communition and concentration.

Extraction and Refining
MME 305 | MME | 1st Semester |

Course Synopsis

This course is designed for students in the field of Metallurgical and Materials Engineering to acquire quality knowledge in the area of extraction and refining of metals. However, students studying mining, mechanical and production engineering are not exempted from the benefits offered by this course as it provides sound knowledge and a dependable background on extraction and refining of metals from their ores. The course aims to give students an understanding of the relationship between the processes used in the extraction and refining of metals that are subsequently used in casting of metal products. In order for metals or alloys to be used in the manufacture of castings or products, the ore needs to be prepared and processed before the metal is extracted. Depending on the type of ore, different extraction processes are used and students need to understand the extraction and refining methods as well as the chemical reactions that take place. The Course also provides an opportunity for students to understand the relationship between extraction and refining processes and therefore support their understanding of subsequent manufacturing processes. The course is an entrepreneurship course that can avail the student the opportunity of becoming self employed after they might have graduated from the University. Topics to be covered in the course include: Mineral processing, comminution, concentration (gravity separation, magnetic separation, froth flotation); energy changes; free energy/temperature (Ellingham) diagrams and their limitations; reactions involved in smelting e.g slag/metal, extraction and refining of common metals, pyrometallurgical, hydrometallurgical, electrometallurgical processes, steelmaking and iron making, extraction and refining of various non-ferous metals.
