I am having trouble finding this information: the quantities of looted vs mined gold by the Roman empire.

How much they looted from the Dacians? How much they looted from the Jews? And how much they mined in Spain and Dacia?

Can someone provide the top 5 (and quantities) in both looted and mined gold from Roman conquered provinces?

Finding loot data is almost hopeless. See my earlier question history.stackexchange.com/questions/6151/… for some pointers. – Felix Goldberg Jul 24 '14 at 12:37
Nothing is more secret than gold. If you had gold, would you go publishing those amounts? Neither did the Romans. – Tyler Durden Jul 24 '14 at 14:03
@TylerDurden Nonetheless there can be estimations, I found here en.wikipedia.org/wiki/Decebalus_Treasure that the Dacians were looted by 165 tones of gold and the Jews were plundered by at least 50 tones of gold timelinesdb.com/listevents.php?subjid=202&title=Jews, Unfortunately cannot find a well documente list, but still researching – Eduard Florinescu Jul 24 '14 at 14:29
@EduardFlorinescu You can "estimate" anything, but its just a guess without reliable, comprehensive information which does not exist. – Tyler Durden Jul 24 '14 at 14:42

I'll only provide some data about the mined gold:

  1. 9 t p.a. "Production in Asturia, Callaecia, and Lusitania (all Iberian Peninsula) alone." (Pliny: Naturalis Historia, 33.21.78, in: Wilson 2002, p. 27)
  2. 190t during whole "Roman Time" in Northwest Spain (I didn't see a specific time range in the paper) (http://www.academia.edu/2105961/Tertiary_and_Quaternary_alluvial_gold_deposits_of_Northwest_Spain_and_Roman_mining_NW_of_Duero_and_Bierzo_Basins_)
  3. Duerna 3t p.a. (http://www.constantinethegreatcoins.com/articles/Edmondson_Mining_in_the_Later_Roman_Empire.pdf quotes Mines d'Or romaines d'Espange)

I wasn't able to find a ranking list or data about the now Balkans (though many references to it, there should be data about tat).

The answer to your question is that these respective quantities are not known.

Modern post-colonial historians routinely speak of how Britain, France, Belgium and other colonial powers looted their colonies by extracting their mineral resources. From this perspective the border between "looting" and "mining" does actually become rather fluid.

The gold of Tolosa was a treasure in a lake where the celts offered many of their warprizes.

However, in 105 BC, the proconsul of Cisalpine Gaul, Quintus Servilius Caepio, reported the discovery of the gold at Tolosa to the Senate, and was charged with sending the treasure back to Rome. Over 50,000 15 lb. bars of gold and 10,000 15 lb. bars of silver were found. The gold disappeared en route, with Strabo mentioning that "it was on account of laying hands on them that Caepio ended his life in misfortunes...". It was reported that the gold was stolen by a band of marauders, with many contemporaries and modern historians believing that Caepio himself had hired them.

that makes 750 000 roman pounds of gold *0.328.9= 246 675 kg or ~ 250 tons of gold!


But however, the account of Poseidonius is more plausible: for he says that the treasure that was found in Tolosa amounted to about fifteen thousand talents (part of it in sacred lakes), unwrought, that is, merely gold and silver bullion

not sure how much that is in kg.
