Slag is a by-product of smelting (pyrometallurgical) ores and used metals, generally. Slag 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).
