Copper ore crushed

Overview
Crushed Copper Ore is an intermediate product used to improve copper smelting efficiency. Instead of sending raw Copper Ore directly into a furnace, the ore is first processed into this crushed form, which allows advanced recipes to produce more Molten Copper from the same amount of ore while reducing unwanted byproducts. The tradeoff is added process complexity: the smelting line needs an extra preparation step and additional filler materials.
This product is mainly relevant when building higher-tier copper smelting arrays. Compared with standard Blast Furnace smelting, recipes that consume Crushed Copper Ore reduce Copper Ore efficiency by 50% but increase Molten Copper throughput by 50%. They also require extra inputs, so the setup is less compact than a basic furnace line, but it is much stronger when the goal is maximizing metal output from limited ore.
The same pattern applies to the higher-tier furnace variants:
- In a Blast Furnace II setup, the crushed-ore route still gives +50% Molten Copper throughput at the cost of -50% Copper Ore efficiency and +2 required filler input.
- In an Arc Furnace II setup, the crushed-ore route also gives +50% Molten Copper throughput and -50% Copper Ore efficiency, while reducing
Coal usage by 87.5% compared with Blast Furnace smelting, switching from 4 Coal to 1
Graphite.
- The Arc Furnace II route additionally shows reduced byproduct output, with both listed byproducts cut by 50%.
Because of these changes, Crushed Copper Ore is best treated as a throughput-oriented refinement product rather than a simple direct-feed material. It is most valuable when copper supply is constrained, when refining capacity is the bottleneck, or when the factory is already organized around multi-step smelting chains. In contrast, if simplicity and minimal handling are more important than raw efficiency, direct furnace smelting remains easier to deploy.
In practice, the product fits into a wider copper-processing chain that trades convenience for better output. Its value comes from letting the player push more metal out of each unit of Copper Ore, especially in advanced furnace setups where the improved yield and lower byproduct generation offset the extra preparation work.
