I do not have the books below, only reference to them, but they look very
hopeful from the titles:
Ruddle, R.W. The Physical Chemistry of Copper Smelting (London: Institution
of Mining and Metallurgy, 1953).
Tylecote, R. F. A History of Metallurgy (The Metals Society, London, 1976)
You will also find a mention of copper regulus in :

I do have Shire Book no 201 Copper & Copper Mining and in the last chapter
it says:
Ore was roasted to carry off some of the sulphur, then smelted in a furnace
to produce a 'matte'. Air blown through the molten matte, oxidised iron
sulphides, leaving a fluid slag which could easily be run off. More air
converted the sulphide to 'blister copper'. This was refined by electrolysis
to remove unwanted metals and to recover silver or gold.
Hope the above may be of some help!

Subject: Copper Terms
Help, please.
I am looking for a reference that will give definitions of the terms used
for the various stages that copper ore goes through in smelting.
Examples include: regulus, copper cake, rosette copper, and blister copper.
All help will be appreciated.
Thanks.
