A doré bar is a partially refined gold bar. Dore bars are typically a super high gold content alloy, sometimes actually pure. However, they have no uniformity or set standard. Gold doré bars are the result of removing all non-metal particles out of the gold ore, and consolidating the gold bearing naturally formed alloy into a single chunk. Most often, gold doré bars have, other than gold, mostly silver left in them, plus often other by-products of the gold mining process.
