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.
A Study on the Copper Recovery from the Slag of the
The work was aimed at the investigation of the influence of the carbon reducer's surface on the rate of copper removal from the slag obtained from the flash directtoblister
Overview of foreign nonferrous smelter technology
sent to the converting furnace. Average copper loss in this waste slag is about 0.4 percent. With lances that introduce blow air, the converting furnace oxidizes the matte to blister copper, which is continuously tapped from the furnace. Slag formed during the converting stage is recycled to the smelting furnace by a moving bucket system.
Recovery of Cobalt and Copper from Nchanga Mines Slag
Recovery of Cobalt and Copper from Nchanga Mines Slag using Ferrosilicon K.L. Kakengelaa, C. Ngúnia, J furnace (SCF) to produce blister copper. The blister copper produced in this process is also laundered to an anode furnace The effect of reductant type and dosage on the recovery of cobalt and copper from Nchanga smelter slag was
Extractive Metallurgy of Copper ScienceDirect
The principal advantage of directtocopper smelting is isolation of sulfur dioxide evolution to one furnace of high sulfur dioxide strength gas. Its main disadvantage is the large amount of copperinslag. The products of directtocopper flash smelting are copper, slag, and offgas with different volumes.
MICROSTRUCTURE CHARACTERISATION OF FREEZE
lining microstructure forming on water cooled steel surface in a highsilica, slag cleaning furnace slag of a directtoblister copper smelter is mostly glassy or amorphous. It contains 530 µm magnetite crystals, very small and larger copper droplets as well as small magnetite and silie nuclei embedded in the glassy silicarich matrix.

ISASMELT Wikipedia
The process used at the Lünen smelter involves charging the furnace with copper residues and scrap containing between 1 and 80% copper and then melting it in a reducing environment. This produces a "black copper phase" and a lowcopper silica slag. Initially the black copper was converted to blister copper in the ISASMELT furnace.
