Mining iron and superheating Iron bars

Introduction to Mining Iron and Superheating Iron Bars
In the industrious world of Old School RuneScape (OSRS), mining iron and superheating it into iron bars offers a dual-skill money-making method that fuses Mining and Magic into a profitable synergy. By mining iron ore and immediately casting the Superheat Item spell to smelt it into bars without a furnace, players can sell the resulting iron bars on the Grand Exchange for a tidy profit while training two skills at once. This method is perfect for mid-level players with moderate Mining and Magic levels, providing a low-risk, efficient way to earn GP that shines with its simplicity and resourcefulness. Whether you’re a skiller aiming to multitask your training or an adventurer seeking a steady income stream, mining iron and superheating iron bars forges a practical path to wealth in Gielinor’s rocky landscapes.
Requirements
This method requires a balanced set of skills and items, accessible to players with some progression. Here’s what you’ll need:
- Mining Level: Level 15 Mining to mine iron ore, though 30+ is recommended for faster rates.
- Magic Level: Level 43 Magic to cast Superheat Item, a key spell for this method.
- Pickaxe: Rune pickaxe (~7K GP) is ideal for speed, though a steel pickaxe (~500 GP) works for lower levels.
- Runes: 1 nature rune (~200 GP each) and 4 fire runes (~5 GP each, ~20 GP total) per cast, or a fire staff (~500 GP) to replace fire runes.
- Gear:
- Prospector Kit: Optional, from Motherlode Mine, for 2.5% Mining XP boost.
- Graceful Outfit: Helps with run energy if moving between spots.
- Inventory Space: 28 slots, split between ore, runes, and a teleport item (e.g., Amulet of Glory).
- Membership: Not required—viable in F2P with iron rocks and Superheat Item available, though members benefit from more locations.
- Initial Capital: 50K-100K GP for a pickaxe, runes, and teleport items, though you can start cheaper with mined ore and a steel pickaxe.
The Magic level and rune supply are the main hurdles, but once met, it’s a smooth operation with low startup costs.
Locating Iron Rocks
Finding a good spot to mine iron ore is crucial for efficiency, as iron rocks are plentiful but vary in accessibility. Here’s where to look:
- Varrock South-East Mine (F2P):
- Location: Southeast of Varrock, near the Champions’ Guild.
- Rocks: 3 iron rocks.
- Perks: Close to Varrock East Bank (~30 seconds), F2P-friendly, low competition on high-pop worlds.
- Al Kharid Mine (F2P):
- Location: North of Al Kharid, near the Duel Arena.
- Rocks: 3 iron rocks.
- Perks: Near Al Kharid bank (~1 minute), F2P viable, quiet on some worlds.
- Mining Guild (Members):
- Location: Beneath Falador, requires 60 Mining.
- Rocks: 3 iron rocks (plus a +7 Mining boost).
- Perks: Bank deposit box nearby, faster rates with boost, less crowded.
- Piscatoris Mining Site (Members):
- Location: North of Eagles’ Peak, requires “Swan Song.”
- Rocks: 2 iron rocks.
- Perks: Quiet, close to Piscatoris bank (~1 minute with teleport).
- Ardougne South Mine (Members):
- Location: South of East Ardougne.
- Rocks: 6 iron rocks.
- Perks: High density, near Ardougne South bank (~1 minute).
Best Choice: Varrock South-East for F2P due to bank proximity; Mining Guild for members with 60+ Mining for the boost and deposit box.
Mining and Superheating Process
This method combines mining iron ore and superheating it into bars in one fluid cycle. Here’s the step-by-step:
- Equip Pickaxe: Wield your pickaxe to free an inventory slot.
- Reach the Rocks: Teleport to Varrock (runes), Al Kharid (Glory), or Falador (Skills Necklace for Mining Guild), then walk to your chosen iron rocks.
- Mine Iron Ore: Left-click an iron rock to mine. Each ore gives 35 Mining XP, filling your inventory with 13-14 ore (~1-2 minutes at 30-50 Mining) alongside runes.
- Superheat: Open your Magic spellbook, cast Superheat Item (1 nature, 4 fire runes, or fire staff) on an iron ore. Each cast smelts 1 ore into an iron bar (56.2 Magic XP), taking ~20-30 seconds for 13-14 bars.
- Bank: Run to the nearest bank (e.g., Varrock East, Mining Guild deposit box), deposit bars, and restock runes if needed. Takes ~30-60 seconds.
- Repeat: Return to the rocks and repeat, averaging 20-25 cycles/hour (300-350 bars/hour).
It’s a rhythmic process—mine, superheat, bank. The fire staff simplifies rune management, and proximity to a bank keeps it flowing.
Profit Analysis
Profit comes from selling iron bars, with costs tied to runes and minimal gear. Here’s a breakdown based on typical Grand Exchange prices as of April 2025:
Item | Buy Price (GP) | Sell Price (GP) | Profit per Bar (GP) |
---|---|---|---|
Iron Ore | – | 100 | – |
Nature Rune | 200 | – | – |
Fire Runes (4) | 20 | – | – |
Total Cost | 220 | – | – |
Iron Bar | – | 400 | 180 |
- With Fire Staff: Cost drops to 200 GP (no fire runes), profit rises to 200 GP per bar.
- Per Cycle: 14 bars x 200 GP = 2.8K GP profit per trip.
- Per Hour: 25 cycles/hour = 350 bars, or 70K GP profit/hour with a staff.
- F2P Mining: Iron ore is free, so profit is 400 GP/bar minus rune costs, or 70K GP/hour with a staff.
Factors Affecting Profit:
- Mining Speed: 60+ Mining with a rune pickaxe boosts rates to 400-450 bars/hour, or 80K-90K GP/hour.
- Market Prices: If iron bars drop to 350 GP or nature runes rise to 250 GP, profit falls to 100 GP/bar, or 35K GP/hour.
- Rune Source: Crafting nature runes (54 Runecrafting) cuts costs to ~50 GP each, adding 30K-40K GP/hour.
Expect 60K-80K GP/hour at 30-50 Mining/Magic, scaling to 90K-100K GP/hour at 60+—a modest but multi-skill earner.
Performance Boosters
Maximizing GP from this method focuses on speeding up mining and reducing costs. Here are some boosters:
- Rune/Dragon Pickaxe: Upgrade to a rune (~7K GP) or dragon pickaxe (~5M GP) for ~20-30% faster mining, adding 10K-20K GP/hour.
- Fire Staff: Always use to eliminate fire rune costs, boosting profit by 5K-10K GP/hour.
- Mining Guild: At 60 Mining, use the +7 boost and deposit box for 450+ bars/hour, or 90K+ GP/hour.
- Rune Crafting: Craft nature runes at the Nature Altar (44 Runecrafting for profit, 54+ ideal) to drop costs to ~50 GP each, adding 20K-30K GP/hour.
- Bank Proximity: Stick to Varrock South-East (F2P) or Mining Guild (members) for <30-second banking, hitting 25-30 cycles/hour.
- High Levels: Train to 60+ Mining and 70+ Magic for 500 bars/hour, or 100K GP/hour with optimal gear.
- Multi-Task: Mine/superheat while semi-AFK (e.g., chatting), but bank promptly to maintain pace.
With these, you can reach 90K-110K GP/hour at 60+, or 120K+ GP/hour with rune crafting—a decent return for its level.
Conclusion
Mining iron and superheating iron bars is a clever, low-risk money-making method in OSRS, forging 60K-120K GP per hour while training Mining and Magic simultaneously. Its accessibility in F2P, moderate skill requirements, and synergy make it a solid pick for mid-level players or those who enjoy multi-skilling. While it won’t rival high-end methods, the Mining Guild, fire staff, and rune crafting can elevate it into a respectable earner. For those willing to swing a pickaxe and cast a spell, it’s a steady path to profit. So grab your gear, head to the rocks, and start smelting—your bank will solidify with every bar you craft.
