1. Bringing predictability into a geometallurgical program : An iron ore case study
Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER
2. Compacted graphite iron : On solidification phenomena related to shrinkage defects
Sammanfattning : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. LÄS MER
3. Characteristics and Sintering of Fine Water-atomized and Carbonyl Iron Powder
Sammanfattning : Various types of iron powder are extensively used in the powder metallurgy (PM) industry. Water-atomized iron powder is commonly used as the base in many low-alloyed steel products manufactured through the conventional 'press and sinter' route, while carbonyl iron powder is often used for metal injection moulded (MIM) components.

4. Morphological characterization of primary austenite in cast iron
Sammanfattning : Automotive industry products portfolio includes a wide variety of complex‐shaped cast iron products, such as truck engine components, that need to withstand a constant trend of higher demands, especially urged by stricter environmental regulations on emissions. Combined with this continued demand on properties improvement, cast iron industry faces a process problem related to the lack of understanding of solidification and mechanisms behind defect formation.

5. A Process Integration Approach to Assessing Possibilities for Improved Material Efficiency in Nordic ore-based Iron- and Steelmaking Systems
Sammanfattning : Iron- and steel production is a material- and energy intensive industrial activity. The production of one tonne of steel commonly results in some 400 kilograms of residual materials such as metallurgical slags, dusts, sludge and scales generated in the processes. LÄS MER
