Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around four million tons of slag are disposed every year, and another 40–45 million tons are historically cumulated. Copper slag contains iron in the range of 42–45%, which can be recovered and recycled along with.
May 25, 2017 . To improve the recovery of copper, the viscosity of copper molten slag is decreased by the reduction of magnetic iron, which, in turn, accelerates the settling and separation of copper droplets from the slag. A new technology is proposed in which waste cooking oil is used as a reductant to reduce magnetic.
The slag material normally contains appreciable amounts of various metal values, including (depending on the nature of the ore) copper, iron, zinc, lead, and other materials all in combination with alkaline earth metals in a matrix of metallic and nonmetallic silicates. The recovery of these metal values has not been found.

Oct 5, 2017 . Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product which can be a feed material for steel making. On the other hand, the non-metallic residue, the secondary slag, can be used in the glass and.
equipment used in the recovery of iron from copper slag,
To improve the process efficiency, lime is used to raise the pH of the water bath, causing the collector to ionize more and to preferentially bond to chalcopyrite (CuFeS2) and avoid the pyrite (FeS2). Iron exists in both primary zone minerals. Copper ores containing chalcopyrite can be concentrated to produce a concentrate.
Characterization of copper smelter slag and recovery of residual metals from these residues. Resumen ..  used three different tests (sulfuric acid leaching, leaching . this calcine, atomic absorption spectrophotometry for copper, iron, gold and silver was carried out, using the Thermo Scientific iCE 3000 Series equipment.
Liquid copper and iron fall to the bottom of the furnace like a molten metal rain, while the sulfur combines with oxygen to form sulfur dioxide gas. This combustion releases a . It will be recovered and sent back through the mill and concentrator to recover any copper that might have been trapped in the slag. The Converter.

copper recovery. Tailings from flotation of copper slag are a second RCRA special waste. Traditionally, reverberatory furnaces have been the most common furnaces used for smelting, however, they are being replaced by electric or flash furnaces, which are more energy efficient. Reverberatroy furnaces also produce large.
Apr 19, 2016 . Slags are remarked as one of the main sources of copper. It is not only regarded as a waste but also identified as another resource extracting base metals. Slags are characterized by copper high grade. Thus, slag copper recovery can be led to different cut-off grades and net present value (NPV).
Dec 18, 2017 . Copper slag, which is produced during pyrometallurgical production of copper from copper ores contains materials like iron, alumina, calcium oxide, silica etc. . In the case of Cu slag, in addition to the above applications, they can also be used as an abrasive for cutting tools, in pavement and concrete,.
Metal Reclamation & Slag Recycling. The DIDION Rotary Dross / Slag Metal Reclaimers are being used to reclaim metal from dross, slag, salt cake, skimmings, spillage, and pot liner in the following materials: Aluminum; Brass; Bronze; Copper; Iron; Nickel; Steel/Stainless; Specialty Alloys.
Copper slag usually contains a certain quantity of valuable metals, such as copper, nickel, cobalt and iron (Gorai et al., 2003). Therefore, it can be treated as a secondary resource for metal extraction rather than as a waste. Numerous studies have been carried out on metal recovery from copper slag, using hydro- and/or.

Several different processes can be used for copper production. The traditional process is based on roasting, smelting in reverbatory fur- naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con- verting for production of blister copper, which is further refined to cathode copper.
