Coal bag (Recommended)
|1,305,300 per hour|
1,272 x Rune bars (17,731,680)
12 x Portable forge (505,596)
Set up a bank preset with a coal bag, 12 runite ores, and 15 coal. The preset should then be configured to be one of the two single-keypress buttons (which can be activated by pressing '1' and '2' respectively). It's recommended to place the coal bag and position the bank window so that the mouse doesn't need to be moved too far to fill the coal bag after opening the bank. The process is as follows: open your bank, fill the coal bag by right-clicking it and selecting fill, activate the bank preset, click the portable forge, press spacebar to start smelting, wait for 28 seconds for the smelting to finish, and repeat the process. Note that you needn't deposit your bars once made, simply pressing the appropriate key to activate the preset button will automatically deposit completed bars.
Using a coal bag is highly recommended since it allows 12 runite bars to be smelted per inventory as opposed to just three. This way the process is more profitable, doesn't require near-constant attention and is significantly less click-intensive.
It should be noted that Grand Exchange has a buy limit of 25,000 per 4 hours for coal, which will limit the use of this method.
It is strongly recommended to check the live prices on the Grand Exchange before making large investments in any method.
