Rock that contains tin ore once mined upon with a pickaxe. It can be mined with any level Mining. Mining 14 tin ore and 14 copper ore (wielding the pickaxe as a weapon to free the 28th inventory space) and smelting them to bronze bars is a slow but effective way to raise mining and smithing.

## Respawn rateEdit

Tin ore, like all other mined rocks, respawns at a rate indirectly proportional to the number of people in the rock's RuneScape world. If the world is empty, the ore respawns in 4 seconds; if it is full (with 2000 players), it respawns in 2 seconds. Thus the respawn rate of tin ore is

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

where x is the number of players in the world.

A table of respawn rates is given below.

Players 0 200 400 600 800 1000 1200 1400 1600 1800 2000
Respawn time 4.0 s 3.8 s 3.6 s 3.4 s 3.2 s 3.0 s 2.8 s 2.6 s 2.4 s 2.2 s 2.0 s

Tin ore has the same respawn rate as copper ore.
