Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Pyrometallurgy - an overview | ScienceDirect Topics

The crude copper is then added to the anode furnace, and the reducing agent is added too.The crude copper continues to be refined to 99.99% of the cathode copper, while the anode mud contains precious metals. After drying, the anode slime would be put into the precious metal melting furnace. The anode slime is first cast into ingots.

Cut Copper still is too expensive – Minecraft Feedback

Cut Copper still is too expensive. Recently they made it so that you can make a copper block with just 4 copper ingots but that's still like 16 ingots for four cut copper. I feel like that can be tweaked slightly, maybe four copper blocks for six cut copper. It feels a lot better now but I still think they can tweak it a tiny bit more.
