How to make Cuprum from Granum Mining?

[Gavinox]

Can someone please share the steps to efficiently getting Cuprum from Granum, or a source that explains it clearly?

I think I need Granum which breaks down in the mill to give me Amarantum, and then I just need to buy rock oil from magic vendor.

I think I need 20/1 Amarantum/Rock Oil respectively, and just use the furnace?

What lores would impact the amount returned, aside from Cuprum lore? Do I need Rock Oil lore or Amarantum lore?

Wanted to ensure I am not missing any other lores and ensuring this process is relatively efficient.

Thanks!

Amarantum lore
Cuprum lore
Furnace operation
Intermediate extraction

These all affect the output of what you're trying to do

Any idea what priority those would be?
