Ore Limit Upgrade: Expand Your Processing Pipeline
The Ore Limit upgrade in Tectonic Industries determines how many ores can be in your base's processing pipeline at the same time. Think of it as the bandwidth of your entire operation -- it controls how many ores can flow through your refiners, storage, and forge simultaneously. With a low ore limit, your powerful refiner chain and Nuclear Forge sit idle waiting for ores to enter the pipeline. With a high ore limit, your machines run at full capacity, maximizing your income per minute.
Despite being one of the less glamorous upgrades, the Ore Limit is critically important for mid-to-late game players. Without adequate ore processing capacity, every other upgrade you have invested in -- from Max Depth to S-Tier refiners -- operates below its potential. This guide explains exactly how the Ore Limit works, covers all 7 upgrade levels, and helps you determine when to invest in this essential upgrade.

What Is the Ore Limit?
The Ore Limit is a cap on the number of ores that can exist in your base's processing system at any given time. This includes ores on conveyor belts, inside refiners, in storage devices, and being processed by your forge. When you hit the ore limit, no new ores can enter the pipeline until existing ones are processed and sold.
This mechanic exists to prevent server performance issues and to create a strategic resource that players must manage. It also ensures that players cannot simply dump thousands of ores into their base and let them process overnight -- there is a maximum throughput that must be respected.
All Ore Limit Levels
The Ore Limit upgrade has 7 levels, starting at 5 ores and increasing to 70 ores at the maximum level. Each level significantly expands your processing capacity.
| Level | Ore Limit | Cost Estimate | Increase | Pipeline Capacity Rating |
|---|---|---|---|---|
| 1 (Starting) | 5 ores | Free | Baseline | Severely limited |
| 2 | 10 ores | Low | +5 (2x) | Basic |
| 3 | 20 ores | Low-Moderate | +10 (2x) | Moderate |
| 4 | 30 ores | Moderate | +10 (1.5x) | Good |
| 5 | 40 ores | Moderate-High | +10 (1.33x) | Strong |
| 6 | 55 ores | High | +15 (1.375x) | Very strong |
| 7 | 70 ores | Very High | +15 (1.27x) | Maximum |
The starting ore limit of 5 is extremely restrictive. With only 5 ores in the pipeline at once, your refiners and forge will frequently be idle, waiting for new ores to enter. Upgrading this limit is essential for making your processing chain efficient.
Why the Ore Limit Matters
To understand the impact of the Ore Limit, consider a simple example. You have a refiner chain that processes one ore every 3 seconds and a forge that takes 5 seconds per ore. With an ore limit of 5, your chain can only have 5 ores moving through it at a time. Once those 5 ores are in the pipeline, no new ores can enter until one exits.
With an ore limit of 70, you can have 70 ores moving through your chain simultaneously. This means your chain is always full, your refiners are always processing, and your forge is always running. The difference in throughput -- and therefore income -- is enormous.
| Ore Limit | Ores Processed/Hour | Income/Hour (relative) | Machine Utilization |
|---|---|---|---|
| 5 | ~60 | 1x | 20% |
| 10 | ~120 | 2x | 40% |
| 20 | ~240 | 4x | 65% |
| 30 | ~360 | 6x | 80% |
| 40 | ~480 | 8x | 88% |
| 55 | ~660 | 11x | 95% |
| 70 | ~840 | 14x | 98% |
Machine utilization represents what percentage of the time your refiners and forge are actively processing ores. At an ore limit of 5, your expensive machines are idle 80% of the time, which is a massive waste of your investment. At 70, they are running at near-full capacity, maximizing your return on every machine you have built.
Level-by-Level Analysis
Level 1: 5 Ores (Starting)
The starting ore limit of 5 ores is functional but barely. It allows you to run a basic chain of 1-2 refiners and a forge, but any more than that and your machines will be waiting for ores most of the time. Upgrade this as soon as you can afford it.
At this level, your strategy should be simple: mine a few ores, deposit them, let them process, and repeat. The low pipeline capacity means you cannot mine in large batches and let your chain process them -- you need to feed the chain continuously in small amounts.
Level 2: 10 Ores
The jump to 10 ores doubles your pipeline capacity. This is sufficient for running a basic chain of 3-4 refiners and a forge with reasonable utilization. Your machines will still have idle periods, but the improvement over 5 ores is immediately noticeable.
This is the minimum ore limit you should aim for before investing heavily in refiner upgrades. Building B-Tier refiners with a 5-ore limit is inefficient because the refiners will spend most of their time empty.
Level 3: 20 Ores
The 20-ore limit is where your processing chain starts to feel productive. With 20 ores in the pipeline, a chain of 4-6 refiners and a forge can run at reasonable capacity. This level is sufficient for the early-to-mid game and allows you to take full advantage of B-Tier and early A-Tier refiners.
Level 4: 30 Ores
The 30-ore limit provides good capacity for mid-game chains. With 30 ores moving through your system, you can run a full chain of B-Tier and A-Tier refiners feeding into an Industrial Forge with strong utilization. This level is recommended before building the Flamethrower, since the Flamethrower's destruction risk is higher when the pipeline is congested.
Level 5: 40 Ores
The 40-ore limit is strong enough for most late-game chains. It provides enough capacity for a full chain of A-Tier refiners and a Pristine Processor to run efficiently. At this level, your machines should be running at approximately 88% utilization, which is quite good.
Level 6: 55 Ores
The 55-ore limit is ideal for endgame chains with S-Tier refiners. It provides enough capacity for the Chemical Sprayer, Blast Smelter, Molten Fabricator, Mini Microprocessor, and Nuclear Forge to all run at high utilization. This level is recommended before fully committing to S-Tier machines.
Level 7: 70 Ores
The maximum ore limit of 70 ores is the ultimate processing capacity upgrade. With 70 ores in the pipeline, your entire chain runs at near-full capacity, maximizing the income from every machine you have built. This level is expensive but provides the best possible throughput for your endgame setup.
Ore Limit vs Other Upgrades Priority
The Ore Limit upgrade should be prioritized based on your current processing chain. Here is when to upgrade the ore limit relative to other upgrades:
| Game Stage | Recommended Ore Limit | Why |
|---|---|---|
| Very Early (BP1-3) | Level 2 (10 ores) | Support basic chain |
| Early (BP4-5) | Level 3 (20 ores) | Support growing chain |
| Mid (BP6-7) | Level 4 (30 ores) | Support Industrial Forge and Flamethrower |
| Mid-Late (BP8-10) | Level 5 (40 ores) | Support full A-Tier chain |
| Late (BP11-12) | Level 6 (55 ores) | Support S-Tier refiners |
| Endgame (BP13) | Level 7 (70 ores) | Maximum throughput for Nuclear Forge |
Ore Limit and Machine Investment Balance
There is a critical balance between investing in better machines and increasing your ore limit. A powerful refiner chain with a low ore limit is like a sports car stuck in traffic -- it has the potential for speed but cannot use it. Conversely, a high ore limit with weak machines is like a wide highway with slow vehicles -- you have capacity but not speed.
The optimal approach is to upgrade your ore limit in step with your machine upgrades. Every time you add a new refiner or upgrade your forge, check whether your current ore limit can support the increased processing demand. If your machines are frequently idle, it is time for an ore limit upgrade.
| Situation | Recommended Action |
|---|---|
| Machines idle frequently | Upgrade Ore Limit |
| Pipeline full, machines busy | Do not upgrade, invest in machines |
| New S-Tier refiner built | Upgrade Ore Limit to Level 6-7 |
| Building Nuclear Forge | Upgrade Ore Limit to Level 7 |
Frequently Asked Questions
What is the Ore Limit in Tectonic Industries?
The Ore Limit is a cap on how many ores can be in your base's processing pipeline at the same time. This includes ores on conveyor belts, inside refiners, in storage, and being processed by your forge. A higher ore limit means more ores can be processed simultaneously, increasing your overall income.
What is the maximum Ore Limit?
The maximum Ore Limit is 70 ores, achieved at Level 7 of the Ore Limit upgrade. This provides near-full capacity for the most powerful endgame processing chains in the game.
When should I upgrade my Ore Limit?
Upgrade your Ore Limit when your machines are frequently idle or when you add new, more powerful machines to your chain. Signs that you need an upgrade include empty refiners, an idle forge, and slow overall throughput despite having powerful machines.
Is the Ore Limit more important than the Backpack Size?
They serve different purposes and are both important. Backpack Size affects how many ores you can carry from the mine, while Ore Limit affects how many ores your base can process at once. Generally, prioritize Backpack Size in the early game (to enable longer mining runs) and Ore Limit in the mid-to-late game (to support growing processing chains).
Can I have more than 70 ores in my pipeline?
Currently, 70 ores is the maximum pipeline capacity. If you need more throughput than 70 ores can provide, the solution is to upgrade your refiners and forge for higher value per ore rather than trying to process more ores simultaneously.
Does the Ore Limit affect mining speed?
No, the Ore Limit only affects how many ores can be in your base's processing pipeline. Mining speed is determined by your drill and equipment. However, a low ore limit can indirectly reduce your effective mining efficiency if your backpack fills up because your base cannot accept more ores.
Where can I learn more about optimizing my processing pipeline?
The Tectonic Industries Discord server has discussions about pipeline optimization and ore limit strategies. The @seenverge YouTube channel also features base setup tutorials that demonstrate optimal pipeline configurations.
