An old engraving of an old white lead mill of the 1800s. It is from a mechanical engineering book of the 1880s. This belt-driven, wood and iron milling machine was used to break up and crush the raw lead mineral after it was mined and before smelting into lead metal. White lead is occurs naturally as a mineral, known as hydrocerussite, a hydrate of cerussite. White lead compounds known as lead soap were used as additive for lubricants for bearings and in machine shops.

Lead-free substitutes have been developed to replace the use of lead because of lead poisoning, and its use has been banned in many products in most countries.
