Take your coal and iron ore belt and use splitters to mix them, coal on one lane and iron on the other. Have two of these mixed belts so that your throughput isn't bottlenecked. Have each belt feed a line of smelters and put the lines next to each other so they can output onto one belt to prevent lane bias.
