Slag from coal
WebbCoal sludge, the liquid coal waste produced by mining activities (also known as slurry), contains heavy metals. The sludge is often kept in impoundments that can leach into the environment, or break open and contaminate an area, such as the TVA Kingston Fossil Plant coal ash spill and the TVA Widows Creek coal waste spill. [4] WebbBoiler slag is a coarse, granular, incombustible by-product of coal combustion and is thus classified as a coal combustion byproduct. It is angular, dense , and very hard.

Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic. Visa mer 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 Visa mer In nature, iron, copper, lead, nickel, and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals.
