Method questions

Frequently asked questions

What energy boundary should I use?

Use the same boundary before and after the trial—such as mill motor only or the complete grinding circuit.

Can throughput improvement reduce kWh/t?

It can, but use measured plant data rather than an assumed improvement.

Does the tool include demand charges?

No. It uses a simple energy price; add demand and time-of-use effects separately.
