They sometimes used mercury, which forms an amalgam with small particles of gold and silver. Miners used mechanical crushing and grinding machines to break up ores for further processing. Early miners used Mexican arrastras or stamp mills, which reached their peak in the late nineteenth century, to crush ores into sand-size particles.

These challenges were met by combining density sorting with wet and dry attachment techniques. The wet attachment processes resulted in the precise separation of small portions of gold sand. The selective attachment processes applied to Egyptian gold ore processing were less suitable for the large-scale production later conducted by the Romans.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being

it also is really useful to extract small gold from ore. The gold mercury amalgam can then be isolated and the mercury is boiled off or removed chemically. This leaves behind relatively small gold. A gold bar has a density of 19.3 grams per cubic centimeters, and mercury, as a liquid, has a density of 13.5 grams per cubic centimeters.
