Coal is one of the most important mined materials in RuneScape, as it is required to smelt all smithable metals above iron (other than gold or silver), in increasing amounts. It is a necessary ingredient to make elemental, steel, mithril, adamant, and rune bars.
Coal can be mined by players with a Mining level of 30 or higher, granting 50 Mining experience per ore mined. After being mined, a coal rock takes 30 seconds to respawn.
27 pieces of coal can be stored into one inventory space by using a Coal bag, obtained from Prospector Percy’s Nugget Shop for 100 golden nuggets at Motherlode Mine.
Along with a sufficient Smithing level, the primary ingredient to make bars is the metallic ore itself and the secondary ingredient is a number of coal. Half the amount of coal is required if using the Blast Furnace.
As with most natural resources, mining coal is the most efficient way to acquire it.
Below is a list of popular locations; for a complete list, see coal rock page.
Members can also get coal by having the subjects of Miscellania gather it upon completion of Throne of Miscellania. In order to gain coal, players must put a number of coins in the coffers and set the subjects so that they will be mining. They will automatically mine coal and a few gems.
Additionally, coal can be purchased from Ordan’s Ore Seller shop, which is located downstairs in the Blast Furnace factory in the eastern side of Keldagrim. It can also be bought at the Ore store ran by Hring Hring in Jatizso. It sells the ores at a lower price than at blast furnace, but it has a much lower quantity in stock. The stock quantity does restore quickly, however.
