Slag, the waste material produced during the smelting process, can be removed from molten metal through a process called slag skimming. This involves using a tool to physically scoop or skim the slag off the top of the molten metal. This is possible because slag is less dense than the molten metal and so it floats on the surface. After skimming, the slag is often discarded or …

Understanding Slag and Fly Ash. Before we compare slag vs fly ash, let's first understand what they are. Slag is a byproduct that results from the smelting process of various ores, such as iron, copper, and lead. When these ores are heated to extract the desired metal, slag is formed as molten, which is later cooled and solidified.

Operating with a low cohesive zone produces slags with a higher FeO content that absorb the SiO. De-siliconization of the HM in the packed coke bed and hearth regions can be enhanced by suitable slag chemistry. Iron oxide (FeO) and manganese oxide (MnO) in the slag can oxidize Si at the metal-slag interface to SiO2, transferring Si to the slag.
