Read More2020-11-2 Casting of alloyed or refined copper products is the final step used by the secondary copper industry in the recovery of copper from scrap material. The molten metal is poured into molds from ladles or small pots serving as surge hoppers and flow regulators. The resulting products include shot, wirebar, anodes, cathodes, ingots, or other cast shapes.

Read More2013-1-19 Based on the source of copper, copper smelter method is divided into two categories: primary copper smelter and secondary copper smelter. If the source of copper material came from earth (ore), then it is primary copper smelter. But, if the source came from scrap (pipe, wire, bushing, bearing, etc), then it is secondary copper smelter.
Read More2015-9-10 Fugitive emissions occur from each process associated with secondary copper smelter operations. These emissions occur during the pretreating of scrap, the charging of scrap into furnaces containing molten metals, the transfer of molten copper from one operation to
Read MoreCopper scrap is smelted in primary (concentrate) and secondary (scrap) smelters. Primary smelters mainly smelt concentrate. Some, however, are well adapted to smelting all grades of scrap. Smelters with Ausmelt/Isasmelt, Mitsubishi, Noranda, reverberatory, and top-blown rotary converter smelting furnaces are particularly effective.
