Reduction of molybdenum oxide from steelmaking slags by pure liquid iron

Alternative Methods for in Situ Determination of Iron Oxide in Steelmaking Slags

The most important component of steelmaking slags is the iron oxide since it serves as the oxidizing agent in refining reactions. The measurement of the iron oxide content is performed in the steelworks by taking a sample out of the liquid slag, cooling it and subsequently analysing it. The procedure takes some time. It would be highly desirable, therefore, to develop methods for rapid in situ ...

Cementitious Properties of Steelmaking Slags

Utilization of ironmaking and steelmaking slags

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

Enzymatic reduction of iron oxide by fungi.

The occurrence of the iron-reducing phenomenon among some common fungi was studied. Results indicated that (i) the reduction of ferric iron to the ferrous state by fungi seems to be restricted to nitrate reductase-inducible strains such as Actinomucor repens, Alternaria tenuis, Fusarium oxysporum, and F. solani and (ii) the amount of dissolved ferrous iron may be reduced progressively by increa...

Biochemistry Metal and sulfur composition of iron - molybdenum cofactor of nitrogenase ( molybdenum - iron protein / dinitrogen reduction / iron - sulfur clusters )

The sulfur content of N-methylformamide solutions of cofactor from Clostridium pasteurianum nitrogenase has been determined to be 11.9 (+0.9) mol per mol of molybdenum. This number was determined radiochemically, using iron-molybdenum cofactor isolated from molybdenum-iron protein from bacteria grown on 35SO4. A total of 3.2 (±0.2) mol of sulfur per mol of molybdenum was found to be present in ...
