Real-world estimates grant the idea that 1 ton of ore yields 1 troy ounce of gold, so 1 ton of D&D gold ore should yield six troy ounces, or just under 0.4 pounds. That's enough to make 20 gold pieces from a ton of ore, so if we discount the costs of refining and minting, 100 pounds of unrefined gold ore should be worth about 1gp, give or take ...

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. …

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
