Slag is Shannon ward smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (byproducts of processing iron and steel), ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous materials like copper, nickel, zinc and phosphorus). Within these general egories, slags can be further .

In this research, steel furnace slag, fly ash and new synthesized polycarboxylate was used to replace cement in concrete composition. Concrete was made in three grades of 400, 450 and 500 using steel furnace slag, fly ash and polymer with different percentages of dry weight. Also, the amount of water to cement was selected as one of the effective parameters in concrete .
The molten slag is lighter and floats on the top of the molten iron. The molten slag comprises mostly silies and alumina from the original iron ore, combined with some oxides from the limestone. The process of granulating the slag involves cooling of molten slag through highpressure water jets. This rapidly quenches the slag and forms
A new process route for the valorization of BOF steel slags combining H2 production and CO2 mineral sequestration is investigated at 300°C (HT) under hydrothermal conditions. A BOF steel slag stored several weeks outdoor on the production site was used as starting material. To serve as a reference, room temperature (RT) carbonation of the same BOF steel slag has been .
increase pH above value of 8,5, thus creating the direct negative effect of ash on soil and indirectly on plants in the soil (2). Slag and ash further contain a part of unburned coal organic matter. Slag and ash are mostly composed of particle size – 2 mm – sand fines, in lesser percent of particles
In addition to coating flash rusting, several copper slag abrasives were selected for mineralogical examination and the scanning electron microscopy and energy dispersive xray analysis (SEMEDXRF). The results are summarized below. • Sample No. 10No metallic copper was observed. SEM work shows traces of combined copper in a few slag particles.
