Mekanism 4X Ore Processing Complete Tutorial

Learn how to quadruple your ore processing in Mekanism with this comprehensive guide. This tutorial walks you through the complete setup of a 4X ore processing line, starting from the basics and building up to the complex hydrogen chloride production system required for maximum efficiency.

Understanding the Production Line Concept

The easiest way to visualize ore processing is to think of it as a production line. In this guide, we’ll use colored wool to represent different material flows. The red wool line represents your main ore production line—ore enters at one end and travels through a series of machines, with additional components added to the sides at specific points to increase processing efficiency.

The key to understanding the difference between doubling, tripling, and quadrupling your ores is recognizing that each step adds extra machines to the side of your main production line. Once you grasp this concept, the entire system becomes much more manageable.

Basic Machine Setup

Start by arranging these machines in sequence along your production line:

Chemical Injection Chamber (input)

Purification Chamber

Crusher

Enrichment Chamber

Energized Smelter

Chest or storage (output)

If you’re a beginner, space these machines out generously to give yourself room to work. Connect them using Logistical Transporters. This basic linear arrangement will serve as the foundation for all your ore processing multipliers.

2X Ore Processing (Doubling)

To double your ore output, the setup is straightforward:

Feed raw ore into an Enrichment Chamber

Pass the output into an Energized Smelter

That’s all you need for 2X processing. The ore simply passes through these two machines and emerges as ingots at double the normal yield.

3X Ore Processing (Tripling)

To triple your ore, add two more machines to your line:

Chemical Injection Chamber (ore input)

Purification Chamber

Crusher

Enrichment Chamber

Energized Smelter

Setting Up Oxygen Production

The Purification Chamber requires oxygen to function. To generate oxygen for your 3X setup:

Use a water pump (or any mechanism to provide water)

Feed water into an Electrolytic Separator

The machine outputs hydrogen from the left side and oxygen from the right side

Route the oxygen into your Purification Chamber

Set up overflow tanks on both hydrogen and oxygen outputs to prevent backing up if either gas accumulates faster than it’s used. This is your oxygen line—represented in blue in the setup visualization.

Once oxygen flows into the Purification Chamber, your ore (now shards) converts into clumps, which then travel through the Crusher, Enrichment Chamber, and Smelter to become ingots. This setup triples your ore yield.

4X Ore Processing (Quadrupling)

Quadrupling requires one additional machine on your main production line: the Chemical Injection Chamber (for hydrogen chloride injection). The complexity lies not in the machine itself, but in producing hydrogen chloride.

The Complete 4X Chain

Chemical Injection Chamber (raw ore + hydrogen chloride)

Purification Chamber (+ oxygen)

Crusher

Enrichment Chamber

Energized Smelter

Hydrogen Chloride Production System

Making hydrogen chloride is the most complex part of the 4X setup. You’ll need three main components: a thermal evaporation chamber, an electrolytic separator (for chlorine extraction), and a chemical infuser.

Building the Thermal Evaporation Chamber

The thermal evaporation chamber converts water and heat into brine:

Build a 4×4 structure using Thermal Evaporation Blocks

You can leave the corners empty

Optional: Place Advanced Solar Generators in the corners to speed up the process

Install one controller block and two valve blocks

Powering the Thermal Evaporation Chamber

To heat the chamber:

Connect energy to a Resistive Heater

Set the heater target temperature to 500°F (you can adjust this value)

Use a Thermodynamic Conductor to pipe heat from the heater into one valve of the thermal evaporator

Use another Thermodynamic Conductor to pump water into the second valve

The controller will convert water and heat into brine

Important: If you’re in a cold biome, you’ll definitely need the Resistive Heater. In hot biomes, you may generate enough heat naturally, but a heater ensures consistent production.

Extracting Chlorine from Brine

Once you have brine, extract chlorine:

Output brine from a third valve of the thermal evaporator

Feed brine into an Electrolytic Separator (same machine used for oxygen/hydrogen)

The left output is sodium (you can dump this—it’s not needed)

The right output is chlorine (this is what you need)

Set up overflow for excess sodium

Combining Hydrogen and Chlorine into Hydrogen Chloride

Finally, create the hydrogen chloride:

Take the hydrogen from your earlier Electrolytic Separator (the one producing oxygen for the Purification Chamber)

Take the chlorine from your brine Electrolytic Separator

Feed hydrogen into the left side of a Chemical Infuser

Feed chlorine into the right side of the Chemical Infuser

The Chemical Infuser produces hydrogen chloride (shown as a dark blue pipe)

Output this hydrogen chloride into your Chemical Injection Chamber

Pipe Color Reference:

Red = Ore line (main production)

Blue = Oxygen line

Grey = Hydrogen line

Dark Blue = Hydrogen Chloride line

Complete 4X Processing Flow

Here’s what happens when everything is connected:

Raw ore enters the Chemical Injection Chamber, where it meets hydrogen chloride

Ore becomes shards

Shards travel to the Purification Chamber (oxygen is added here)

Shards become clumps

Clumps travel to the Crusher

Clumps become dirty dust

Dirty dust travels to the Enrichment Chamber

Dirty dust becomes clean dust

Clean dust travels to the Energized Smelter

Clean dust becomes ingots (4X output)

Summary

Mekanism’s 4X ore processing system is complex but logical once you understand the production line concept. The key steps are:

Start simple: Build your basic machine line

Add support systems: Thermal evaporation for brine, electrolytic separators for gases

Create hydrogen chloride: Combine hydrogen and chlorine in a Chemical Infuser

Integrate everything: Feed all materials into the correct machines in sequence

This system takes time to build and understand, but the 4X ore multiplier makes it well worth the effort. Start with 2X and 3X processing first if you’re new to Mekanism—the principles scale up logically.
