Copper processing Roasting, smelting, and converting

Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a “ blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
