Gold washings are the traces of gold left behind after the extraction of gold from its ore or alluvial deposits. There are several synonyms for gold washings, including gold dust, gold flakes, and gold nuggets. Gold dust refers to the fine particles of gold that are often found mixed with sand and gravel. Gold flakes are larger in size and are generally visible to the naked eye. Gold nuggets, on the other hand, are solid pieces of gold that can vary in size from small grains to large rocks. Other synonyms for gold washings include gold particles, gold residues, and gold sediment.
