Slag is mainly a mixture of metal oxides and silicon dioxide. Broadly, it can be classified as ferrous (co-products of processing iron and steel), ferroalloy (a by-product of ferroalloy production) or non-ferrous / base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). [2] .

Slag is one of the substances most commonly mistaken for meteorites, as it appears burned and melted on the surface and often sticks to a magnet due to its high iron content. It is used in road and railroad building, as ballast, and even in the manufacture of fertilizer.

If a rock has vesicles (tiny holes created by gas escaping from cooling molten rock). Commonly Found Meteor-wrongs: Slag- Also called cinder or runoff. One of the most commonly found meteor-wrongs. Has vesicles, which meteorites don’t have. Often mistaken for a meteorite because of its melted look and is found everywhere.

2015年6月1日 · Molten Fe slag can solidify by slow cooling under atmospheric conditions (air cooled), moderate cooling with the use of controlled amounts of water (expanded or foamed), quick cooling in air (pelletized), or quenching with high …

2023年3月16日 · Slags are residues from pyrometallurgical processes which form in the molten state when a metallic and a silicate melt segregate. Slags are the silicate melt whose metallurgical function is to incorporate those chemical constituents …

2015年1月1日 · For this reason this paper is focused on the characterization of three synthetic slags. The main objective of the study is to characterize the slags: a) improve the melting process operation, b) to analyze the environmental impact, c) to determine the possibility of …

2023年8月21日 · Slag that has been melted into a liquid state at high temperature is called dross. Dross is a type of metallurgical melt. Dross condenses into a rock or glassy material, which can be regarded as a crafted rock.

2022年10月25日 · Blue slag is a man-made rock created as a by-product of iron smelting. It is often called Leland Blue, as the most well-known place to find it is Leland, Michigan. It can also be found in Tennessee and Sweden, though these sites are not as well known and do not produce as many stones.

German name for bluish slag from the Steinrenner Hütte (smelter) that smelted the iron ores from the Eisensteinberg. Named for the Sieber river (Sieber valley), Harz, Germany. Bodeachat is a similar bluish slag.
