Converting_(metallurgy)
Converting in copper metallurgy . A mixture of copper and iron sulfides referred to as matte is treated in converters to oxidize iron in the first stage, and oxidize copper in the second stage. In the first stage oxygen enriched air is blown through the tuyeres to partially convert metal sulfides to oxides: FeS + O 2 = FeO + SO 2 CuS + O 2 ...

Vertical vs. Horizontal quench
So if it's horizontal in the forge, I'd quench it horizontally. Vertical heating and quenching would be better though (if you can heat it vertically), as the forces on the blade are much less when you carry it, which makes the chance of bending it a lot less. Another thing is that if you quench it entirely horizontal, there's a good chance the ...

Extractive Metallurgy of Copper | ScienceDirect
Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was ∼$9/kg.
