A Neural Network Model for SAG Mill Control
SAG specific power range of about 3 to 9 kWh/t for this site. The design of the ore stockpiling and conveying system contributes to fluctuating size distribution with significant shortterm segregation occurring under certain operating situations. Depending on ore type and feed size distribution, each SAG mill will process between 700 and 3000 tph.

[] What are the best ways to process ores ...
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.
