Buy from worlds until there's less than 28 ore left. You can bank more than 11,000 gold ore per hour if the Worlds are full, but 8,000–9,000 is more realistic, doing 3 inventories per World. Alternatively, players can attain more than 300,000 Smithing experience per hour, but the experience rate varies heavily depending on stock/click speed.

Not all refractory gold ores give a large recovery improvement after fine milling. Gold locked in arsenopyrite for example does not achieve the same gold recovery as gold disseminated in pyrite due to the smaller gold particle size of the locked gold (Figure 5). Figure 5. Gold Recovery of Arsenopyrite and Pyrite Ores 50 55 60 65 70 75 80 85 90 ...

The Gold Flotation Process means that gold ore is generally crushed by gold mining equipment (crusher equipment, Jaw crusher), crushed by gold processing equipment (ball mill), and treated by gold panning equipment such as flotation machine, etc. Through gravity separation, flotation machine, extraction of metals from ores, and then the application of …
