For many people, coffee is the drink of choice first thing in the morning. The beverage made from what adults think of as magical wake-up beans gives the boost of energy many need to get out of bed.
Cuprous oxide reacts with cuprous sulfide to convert to blister copper upon heating: 2 Cu 2 O + Cu 2 S → 6 Cu + 2 SO 2. This roasting gives matte copper, roughly 50% Cu by weight, which is purified by electrolysis. Depending on the ore, sometimes other metals are obtained during the electrolysis including platinum and gold.
