  • Primary mills consist of three semi-autogenous (SAG) mills and two autogenous (AG) mills. The SAG mills are comprised of two 9.75 metre diameter by 4.72 metre long fixed speed mills and one 10.36 metre diameter by 4.88 metre long variable speed mill. Each primary grinding line is supported by two secondary ball mills at 5.03 metres in diameter.

  • This is probably the best/easiest way to start. The machines are simple cheap and are easy to config. Use a Sag Mill to turn the ore into 2 dust then a Alloy furnace to turn into ingots. The best part is they both can process 3 items at a time(3 of the same type) So they can smelt 3 iron into bars at the same time for example.
