Dalmia - Slag Cleaning
There are two types of Electric Arc Furnace (EAF) designs based on Tapping Device – 1.EAF with Launder Tap, where the molten metal is teemed from the furnace through a Launder system. 2.EAF with EBT System, where the molten metal is teemed through a Tap hole device from the bottom of the furnace.
Working Of Copper Slag Cleaning Furnace
The copper slag cleaning in an electric furnace is based on slag reduction and settling of copper matte inclusions Copper recovery depends on the slag temperature degree of magnetite reduction and slag residence time The formation of solid buildup on the furnace hearth leads to the decrease of furnace volume and slag residence time affecting copper recovery and furnace capacity .

12.3 Primary Copper Smelting
Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte. All but ...
Copper slag - Wikipedia
Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece.
