gold in coal fly ash from indonesia

Fly ash, produced during the burning of coal, is a fine173-grained solid derived from noncombustible constituents of coal, such as clay minerals and quart. When coal is burned, REEs are retained and enriched in the fly ash and, as a result, fly ash has long been considered a potential resource for REEs.
