I'm planning to use a two-fluted carbide end mill from McMaster - are their end mills typically sharp enough for cutting copper?

 — However, concentration methods such as froth floatation separate the copper minerals from the waste rock for more tricky ores, such as sulfide ores. The sulfide ore is then roasted or smelted into a purer copper concentrate called a slab. Finally, the copper slab undergoes electrolysis, resulting in 99.99% pure copper cathode slabs.
