This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two one-year campaigns (2016 and 2017). The first campaign was carried out using an existing copper slag flotation circuit in the plant.
For this purpose, it uses existing flotation line (mill section B) for copper slag processing in the Bor flotation plant. The projected capacity of the copper slag processing is 340.000 tons per year with an average copper content of about 2 %. This amount of copper slag will be obtained from 290.360 tons/ year from the Flash process technology ...
The Eti Bakır Company basically consists of six main facilities (Figure Figure1 1): a copper smelter plant, a flotation plant, a sulfuric acid production plant, an electrolysis plant, an oxygen plant, and a crystallized ammonium sulfate plant. In the copper smelter plant, 99.9% pure cathode copper is produced using flash furnace …
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% Fe equivalents to those in the copper and iron ores, respectively. Most of the research was focused on the recovery of iron from the …
The performance of copper slag flotation is significantly improved through the proposed approach, which provides an idea for improving the recovery of copper slag …
KEX concentration as a function of flotation time for flotation test SL28 (self-pulverising pilot plant slag). Note KEX additions of 100, 50, and 50 g/t made at 0, 15, and 30 min respectively. Flotation periods are 6–14, 17–25 and 32–36 min.
In this study, a hydrometallurgical method for the recovery of copper, cobalt, and zinc from copper slag flotation tailings (SFT) was investigated. SFT contains large amounts of valuable metallic compounds, such as copper, cobalt, and zinc. A representative SFT sample containing 0.50% Cu, 0.148% Co, 3.93% Zn, and 39.50% Fe was used in …
For this purpose, it uses existing flotation line (mill section B) for copper slag processing in the Bor flotation plant. The projected capacity of the copper slag processing is 340.000 …
Detailed process oriented characterisation on representative samples from plant survey of the slag flotation plant belonging to Aurubis, Bulgaria has been realised in order to evaluate the mineralogical occurrences of Cu, Ni, Mo and Co bearing phases. The slag subjected to flotation consisted in majority of fayalite, magnetite-iron oxides and a ...

Several plants recover the copper contained in the copper slag by flotation. This method is generally appropriate for liberated metallic copper and sulfide minerals. It is unsuitable for recovering base metals such as cobalt, zinc, and nickel and forms of oxides or doped slags (Aatach et al., 2020).
Owing to the selective oxidation and uneven combustion that occur on the surface of carbon anode, some carbon particles detach and form carbon residue, which is defined as spent anode slag (SAS). The highly graphitized and toxic impurities such as fluorite (CaF2), corundum (α-Al2O3), and cryolite (NaAl11O17) are crucial components of …
A sample of slag from the Flotation Bor, RTB Bor, was mineralogical tested after granulation in the laboratory conditions. Minerals contained in the sample of granulated slag are: fayalite and ferrite
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Shamsi et al. [] studied the effect of copper slag particle size on the flotation effect, the highest copper recovery efficiency of 79.89%was achieved when the grinding time was 80 min and the grinding size was 48 μm [].Sibanda et al. [] controlled the size of copper slag and flotation reagents to improve copper recovery by 16% when the …

Slag Flotation Plant. The slag from the customer's smelter furnace is processed at the Slag Flotation Plant (SFP) via various minerals processing technologies. The SFP plays an important role in extracting maximum value from the ore. In 2016, during the early installation phase of the customer's new SFP, Outotec undertook a …
Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...
The reclamation plant at NCS consists of a milling circuit, which produces a fine circuit product (75% passing 45 microns) at 25 tons per hour that is fed to a flotation …
Accompanying with the pyrometallurgical processes of copper, a large number of copper smelting slag is generated, in which. the average content of copper reaches more than 1% (reaching or even exceeding China s copper ore grade for smelting). Chinas output of copper slag is up to 15. million tons per year [2].
An evaluation of the modal analyses performed around this copper flotation circuits revealed the following: During the plant survey the copper rougher circuit recovered about 60% of the copper, 20% of the …
