Recovery of Cu-Fe Alloy from Copper Smelting

Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 wt% Cu and 35–45 wt% In order to maximize the utilization value of copper slag, a process of smelting copper–iron alloy with copper slag is proposed here. The reduction kinetics of copper slag by H2 are studied in this paper. The main phases of the copper slag were Fe2SiO4 and Fe3O4. The suitable conditions of reduction were a temperature of 1373.15 Minerals Free Full-Text Reduction Kinetics of Copper Slag

Stepwise Utilization Process to Recover Valuable Components from Copper

Waste copper slag is a typical hazardous solid waste containing a variety of valuable elements and has not been effectively disposed of so far. In this paper, a stepwise extraction process was proposed to recover valuable elements (copper, iron, lead and zinc) from waste copper slag. The specific procedures are as follows: (1) A flotation The chemical composition of copper slag depends on the treatment process and furnace type, and is typically 30–40% Fe, 35–40% SiO 2, ≤10% Al 2 O 3, ≤10% CaO, and 0.5–2.1% Cu . A significant portion of the produced slag is stockpiled [ 1 ], an option that may result in environmental and space challenges [ 2 ].Efficiency of Chemical and Biological Leaching of Copper Slag

Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. In general, phosphate cements have a very rapid setting reaction at room temperature. The same holds for copper slag-based phosphate cements. This means that using them as a binder, for instance as mortar, is always possible on a small scale, but very difficult on a large scale.

A new method of full resource utilization of copper slag

Sarfo et al. (2017) carried out carbothermal reduction process of copper slag (from the United States) by mixing 12.5% carbon with copper slag and reacting at 1420 °C for 0.75 h. The initial copper slag is reduced to low-grade pig iron with the recovery efficiency of up to 90% (Sarfo et al., 2017). However, non-ferrous metal elements can In the El Teniente Converter, for example, the slag is forwarded to the El Teniente Slag Cleaning Furnace Process, which is a batch decoppering process that reduces magnetite and copper contents in the slag. This is achieved through the injection of a solid, liquid or gaseous reductant directly into the equipment.Chemical Composition Data of the Main Stages of Copper
