How is slag removed from molten iron? - Quora

Answer (1 of 4): Slag is less dense than iron so it floats on the surface. In a blast furnace the hot metal comes out of the tap hole in the side of the furnace and goes down a trough or runner. A refractory coated skimming blade skims the surface of the hot metal, directing the lighter slag off ...

Coal slag, also known as boiler slag, is a recycled product produced by coal-burning plants. When coal is "fired" at over 2,500 degrees, it melts and produces a by-product called slag. The slag is cooled through a process called vitrification which causes it to solidify and form sharp, angular granules in a variety of sizes.

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by ...
