A process for reclaiming the manganese from the dust produced by furnaces making manganese alloys, which process includes mixing the dust with oxides of iron and manganese, wetting, 8a compressing, and drying the mixture, charging the dry mixture with scrap into an electric furnace, melting the charge, and adding to the slag formed a mixture of ...
leaching to recover manganese from steel plant slag. This investigation showed that treatment of the slag in hydrogen prior to leaching enhanced manganese extraction. Up to 80 pct of the manganese and 50 pct of the iron could be extracted from a silicon steel slag that had been pretreated in hydrogen at 7000 C. Two 4-h leaching stages conducted at ambient temperature with a solution containing ammonia
The manufacturing process of the seawater resistant cement comprises the following steps of pre-extruding to crush the cement clinker, the gypsum, the resistant components, the active silica and...

Steel slag is a by-product of the steelmaking process. It is composed of various oxides oxidized in the smelting process by impurities such as silicon, manganese, phosphorus and sulfur in pig iron and salts generated by the reaction of these oxides with solvents. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide.

Aug 01, 2009018332Chemical composition of the weld pad prepared with pure slag shows lesser amount of carbon 0.028, silicon 0.13 and manganese 0.547 and does not fulfill AWS requirements. As there were no deoxidizers available in the slag, which have already been exhausted, and due to presence of oxygen, the above elements might have been lost by oxidation.
Silicon could promote the yield of plants. There was a lot of active silicon in steel slag that could be absorbed by crops, so many researchers used steel slag as raw material to produce steel slag silicon fertilizer, which was mainly applicable to wheat, rice, corn, and sugarcane, among which rice was the most significant .
Apr 04, 2018018332Out of Indias 142 million hectares of arable land, 49 million hectare is covered by acid soils. The use of steel slag may be one of the most green solution, which may avoid accumulation of large wastes in steel plants as well as help in treatment of soil for improving crop productivity at low cost, according to the steel ministry.

with aluminum, silicon and phosphorous to form slag. Slag then floats to the top of the melt, is poured off, and sent to disposal. Slag starts its life at about 2,700oF and cools almost immediately.
Slag can also be used as filler for land reclamation and landscaping the Old Works Golf Course being a prime example of such reuse. The material has also been used as ballast heavy material placed low in a vessel to increase stability in trains and ships. For more information regarding slag or other Superfund
