2. 1. Characterisation of Muko iron ores (Uganda( for defferent routes of iron production

   Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron ore; iron; characterization; physical and metallurgical properties; sinter; pellet; blast furnace; direct reduction; Muko; Uganda; Materials science; Teknisk materialvetenskap; SRA - Production; SRA - Produktion;

   Abstract : Iron and its products, especially the various forms of steel, have been and still are a vital material in many sectors of life. It is utilized in many industrial activities ranging from production of heavy duty mechanical equipment to light electrical appliances and home appliances. With the world‟s iron ore consumption estimated to stand at 1. READ MORE

4. 2. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

   Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; Henrik Saxèn; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

   Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

5. 3. Some aspects of hydrogen reduction of iron ore

   Author : Oscar Hessling; Pär Jönsson; Du Sichen; Niklas Kojola; Henrik Saxén; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; reduction; iron ore; mechanisms; microstructure; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Fines of hematite and magnetite were studied in the fluidized bed using a pure hydrogen atmosphere in the temperature range of 768 to 888 K. Hematite pellets were studied based on Thermogravimetric Analysis (TGA) experiments using hydrogen atmospheres containing 0–15 % pH2O, in the temperature range of 873 to 1173 K. READ MORE

6. 4. Drying of iron ore pellets : analysis with CFD

   Author : Anna-Lena Ljung; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. READ MORE

7. 5. Adsorption of surfactants and polymers on iron oxides : implications for flotation and agglomeration of iron ore

   Author : Elisaveta Potapova; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Abstract : Iron ore pellets are an important refined product used as a raw material in the production of steel. In order to meet the requirements of the processes for iron production, the iron ore is upgraded in a number of steps including, among others, reverse flotation. READ MORE
