Copper Smelting Process - Furnaces Used, By-Products,

2010-4-9  The copper ore become molten copper droplets that fall to the bottom of the furnace forming a molten copper layer with a slag floating on top of it. The molten copper is tapped and sent through the same processes as the reverb smelted copper, except for the converter stage, as it has been already converted to blister copper in the flash furnace.

Smelting - an overview ScienceDirect Topics

Smelting is an energy-intensive process used to refine an ore into usable metal. Most ore deposits contain metals in the reacted or combined form. Magnetite (Fe3 O 4), hematite (Fe 2 O 3), goethite (αFeO [OH]), limonite (the generic formula for limonite is FeO [OH].nH 2 O), and siderite (FeCO 3) are iron ores, and Cu 5 FeSO 4 is a copper ore.
