Copper Slag Concentrator

Copper extraction - Wikipedia

Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters …

Copper Slag - an overview | ScienceDirect Topics

Copper slag granulated by water quenching produces vitreous amorphous solid particles that show higher chemical stability than those air-cooled solidified (Pavéz, Rojas, Palacios, & Nazer, 2004). The chemical composition of copper slag varies with the type of furnace. The typical composition of smelting slags is Fe (as FeO, Fe 3 O 4) 30–40%; SiO 2 35–40%; Al 2 O 3 up to 10%; and CaO up to ...

Recovery of Copper from Reverberatory Copper Slag and ...

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. The process also has reduced flotation recoveries and requires high ...
