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 …

Tailings are high in moisture (approximately 80%) and can be quite variable. Depending on soil contamination, beet tailings have a feeding value similar to or higher than corn silage on a dry-matter basis. Choking may be a problem with beet tailings. Due to the high moisture content, transportation is a major expense with beet tailings.
