Biodegradable Quaternary Ammonium Salts for Processing Iron Ores
Two biodegradable quaternary ammonium salts were synthesized and used as cationic collectors in processing iron ores by froth flotation. The flotation behaviors of iron minerals with the new biodegradable quaternary ammonium collectors were investigated by micro-flotation tests of quartz (SiO2) and magnetite (Fe3O4). It was observed that the new biodegradable collectors were effective in separa...
متن کاملKinetics of Reduction of Iron Oxides and Ores by Carbon
ITIHEORETICAL considerations and experimental findings point out that reduction of iron oxides and I ores by carbon proceed via the gas' phase, whenever the latter is present. The overall reaction is a coupling of the following two component reactions, viz., Gasification of carbon C(S) CO2 (g) = 2C0 (g) and Reduction of iron oxide mFe.0y(S) -fCO (g) = nFezOw [S) CO2 (g) ' Recent kinetic studies...
متن کاملManganese and Iron Binding to Human Transferrin
The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

متن کاملDetermination of Relationship between Autoignition of Sponge Iron and Specification of the Iron Ores
Sponge iron (DRI) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). In this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. Isothermal and non-isothermal re-oxidation experiments were carried out on each type of DRI and their autoignition...
