The aim of the study was to investigate leaching mechanism andBa(OH)2Characterization of Ladle Furnace Slag from Carbon Steel .A promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF). The use of the LF slag in further applications requires ...Using Secondary Lead Smelter Slag in Ceramic BricksSecondary lead slag is a waste product obtained from the smelting of used lead battery, and it becomes a major air, soil, and water pollutant when not properly stabilized. Thus, this study assesses the technical feasibility of aggregating this waste to produce ceramic bricks and to test the immobilization of several heavy metals contained in the slag used for prepared products.Using technology to reduce waste and costs in the secondary lead .Slag 5 % Fumes Recycling 2 -3 % NH 3 DeS NH 3 DeS (NH 4)2 SO 4 F.A.S.T.
