Ore processing in Mekanism is probably the best use of Mekanism’s factories. The first tier of ore processing is just the standard 1 ore =1 ingot. This process used an Energized Smelter to process the ores. The next level is ore doubling, using an Enrichment Chamber to turn the ores into 2 dusts then smelting those in the Energized Smelter to get ore doubling. Tier 3 is more complicated, using a Purification Chamber to grind the ores into 3 clumps. Then a Crusher turns these clumps into dirty dusts, finally an Enrichment chamber turns the dirty dusts into dusts and an Energized Smelter turns those into ingots. These three levels of ore processing are the most commonly used, as the other 2 tiers require late game items, such as obsidian ingots. This system can be made even more efficient with the use of factories, which can process up to 8 items at a time.
