The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation …
The Slag Mill Plant achieves on average copper recovery of 75% and a tailings grade of 0.65% copper. Copper minerals in slags are made up of elements in the mother ore, however, fluxing to aid the smelting process also contributes to the mineralogical composition of the slags. ... Slag cleaning is the process of removing wanted minerals …
The copper concentrate is submitted to the smelter and converter, creating matte, white metal and blister copper, and slag in several steps. The slag is normally submitted to a slag cleaning process including another comminution, flotation and smelting cycle, while the final slag is discarded.
Electromagnetic stirring in a copper slag cleaning process aims at improving the recovery efficiency of the finely dispersed metallic materials from the waste.
The ability to efficiently remove impurities contained in concentrates is a key point to consider when selecting copper smelting technology for new plants or modernisation projects.
Levels can also be controlled using slagging and slag cleaning at the smelter and electrolyte purification in the refinery. ... Hot flue dust energy can be used for leaching reactor heating and impure wash acid or wastewater from the acid plant can be utilized in leaching. ... The first method removes copper first from the solution using ...
Five parts per million of arsine were found to be present in the atmosphere during slag washing, but higher levels would have occurred on the occasions when slag from the making of an aluminium copper alloy from copper with an …

BLASSTING and CLEANING procedure : Nozzle size:5/6 – 1/2 inch Air / Grit mixtureThe grit valve is to be set at a lean feed. Too much grit in the air flow results in low production and ...
Therefore, it is very important to collect soot volatilized from the copper slag in the molten state to reduce environmental pollution. The mass of the reduction slag, ingot iron, carbon, and volatiles were obtained. The mass percentages of copper slag, lignite, and CaO before reduction were 314.60, 52.61, and 93.92 g, respectively.
Air-cooled and granulated copper slags have several favourable mechanical properties for use as aggregates in construction such as excellent soundness characteristics, excellent abrasion resistance and good stability (Gorai et al., 2003).These properties of copper slag make it suitable as a partial or full replacement for Portland …
Copper slag used in this study was cooled by water quenching, from a copper smelting plant, China Minmetals Corporation. The copper slag was first crushed and ground into −200 mesh powder before the experiment. XRF-1800 X-ray Fluorescence spectrometry (XRF) (Shimadzu, Japan) chemical analysis result is shown in Table 1. …
During about 40 years of copper production, about 8 million tons of slag with an average Cu content of 1.67 wt%, 40–56 g/t Ag, 1 g/t Au and 0.05 wt% Mo as a metallurgical waste has been disposed of by a way of stockpiling at a place near the refinery plant, and at present, about 750,000 tons per year of slag are added to the slag …

Large amounts of solid wastes are produced in copper and aluminum smelting processes, which not only cause losses of valuable resources but also threaten the ecology and environment. In this study, a reduction–sulfurization smelting method was used for recovering Cu and Co from converter slags by using spent pot lining (SPL) as the …
Fig. 1 shows the QBSD (quadrant backscattering detector) micrographs of main phases present in the raw material. From Fig. 1 (SEM-EDS), it was deduced that copper was present in three phases namely cuprite (Cu 2 O), delafossite (CuFeO 2) and metallic copper (Cu). Fig. 1 c and d also showed that the copper rich slag has small …
Copper slag is one of the mining wastes that is raising growing concern due to the huge volumes being produced and dumped annually worldwide. These huge …
Copper slag is a by-product obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. …
During the last few decades, the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized. The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most …
As part of the 2002 copper concentrator upgrade, a dedicated, slag cleaning, Jameson Cell, model E2532/6 was installed for cleaning of both converter and RHF slags ( Figure 15) (Carr et al 2003 ...

Materials. The smelting slag used in this study was obtained from a copper plant in China. Mineralogical analysis, performed using scanning electron microscope (SEM) and energy dispersive X-ray spectroscope (EDS), polarizing microscope and X-ray diffraction (XRD), indicated that fayalite (Fe 2 SiO 4) and magnetite (Fe 3 O 4) phases …
Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is ... sulfuric acid plant to treat copper smelter effluent gas streams ...
Copper slag, generated mainly during copper smelting, and classified as a potentially harmful waste, is an important secondary resource containing not only valuable metals, such as Cu, Fe, Zn, Co and Ni, in abundant quantities, but also hazardous …
