Respawn Rate
Mithril ore, like all other mined rocks, respawns at a rate inversely proportional to the number of people in the rock's RuneScape world. If the world is empty, the ore respawns in 4 minutes; if it is full (with 2000 players), it respawns in 2 minutes.

$$4-\frac{x}{1000}$$

For example; if there are 1000 players on world 3 then the mithril ore will respawn in 3 minutes.
