.

XP-only method

If you have some other leftover ores, the general approach is to smelt bars and then use most of them per craft by smithing platebodies if they're unlocked. You can smith other items - it will just take longer because the XP per used bar is always the same.

The method below assumes that you have Mining Skillcape. If you don't have it yet, please refer to Mining/Training.
The idea of the method is to make items that take most bars per craft.

Mine ores
Smelt bars
Make items that eat most bars. The best one is the highest available Platebody. Stop on Rune Platebody and do it until

Level 99.
Use Smithing Gloves if you can afford to maintain charges above zero.
If you have not enough coal and will need Rune Essence in the future, mine it with Mining Skillcape. Otherwise mine Coal Ore with it.
Use Mining Gloves if you can afford to maintain charges above zero.
Sell created platebodies.

The table below shows how many bars you need to smelt and then use to create items with in order to reach the next threshold. The Steel Bar is skipped because it triples the mining time, and you're likely to overmine something with such short timings.
It should be also noted that the number below are for the barebones setup without or any XP bonuses. With bonuses, the number of required bars is lower.

Details
The number of bars was calculated by using the "Melvor Idle Rate & Resource Calculator" by Kidbiz20 from Spreadsheets_and_Theorycrafting and then adjusting the number from the column "Resources to Level X" by the fact that we account for the XP from the bars that are need for the items. For instance, to go from level 40 to 55, you need 2,589 Mithril Bars if you craft items. If you account for the XP from the required bars then it's [math]\displaystyle{ x\times 50 + x\times35 = 2589\times 50 }[/math], [math]\displaystyle{ x = 1523 }[/math].

Level	Item	Bars without Gloves	Bars with Gloves
1-10	Bronze Bar	78 231 if just bars	49 145 if just bars
10-30	Iron Bar	437	274
30-40	just Silver Bar	1591	995
40-55	Mithril Bar	1523	952
55-70	Adamantite Bar	5600	3500
70-99	Runite Bar	98375	61485

Useful Items method

The idea of this method is to create the items that you will use to buy things or level other skills.

The table below provides notable examples where the bars can be used.
