This blueprint is for a factory with 2 inputs and 2 outputs. Just hook up your inputs on the left and your outputs on the right. Connect power to the middle pole.

Recipe: Copper Alloy Ingots

Power Usage: 192 MW

Inputs:

• 600 Copper Ore/min
• 300 Iron Ore/min

Outputs:

• 1200 Copper Ingots/min

You can do a fair bit to optimize this blueprint for resource usage. You can delete the steel beams and foundations and optimize power connections. There's also a lot of room for aesthetic improvements, namely with walls, power connections, and support structures for belts & mergers. Mk 5. belts and lifts are used everywhere for efficiency, you might want to change this depending on your belt speed opinions.

I tried to leave this fairly barebones for further customization. Enjoy!
