UG-Mat Nonferrous Slags Recycled Materials Resource
Copper Slag Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment applications. Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145. (11) Unit Weight: Copper slag
Recovery of Copper from Reverberatory Copper Slag and
2016-6-8 concentrate, various mining operations have initiated the recovery of copper from dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag.

Biorecovery of copper from converter slags: Slags
2009-6-1 The heaviest molten phase obtained is periodically tapped from the furnace and sent to a converter for its conversion to blister copper. 2. Slag is subjected to cooling/solidification, crushing, grinding and flotation to obtain a 30 to 60% Cu-concentrate (Rao and Nayak, 1992).
Comprehensive review on metallurgical recycling and
2021-5-1 The copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper losses of most plants in the discarded slag limited between 0.8 wt.% and 1.0 wt.% (Coursol et al., 2012). However, the final copper slag still contains large amounts of valuable metals
