6. Minimisation of Chromium Leaching from Low-Alloy Electric Arc Furnace Slag by Mineral Modifications
Sammanfattning : Iron and steel are produced continuously as a vital part of modern life. The largest by-product of metal production is slag. Slag is an essential part of the production of steel since, in the furnace, the molten slag removes impurities from the metal. When the slag which consists of oxides, solidifies minerals form.

7. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies
Sammanfattning : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. LÄS MER
8. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction
Sammanfattning : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. LÄS MER
9. Ecotoxicological classification of ash materials
Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER
10. Process Development for Extraction and Separation of In and Y from Discarded Flat Panel Displays
Sammanfattning : From the time of their invention in the 1970s, flat panel displays (FPDs) have slowly become the most used type of displays in televisions, computers, and cell phones. A major subgroup of FPDs is lLiquid crystal displays (LCDs). LÄS MER
