1.2. Objectives. The objective of this present study is to characterize the BCL copper slag and analyze its composition properties. In the past, research has been focused on ferrous and non-ferrous slags with the intention of employing the findings in various applications [].We had to carry out the characterization task first in order to quantify the …
of copper slag is generated each year from world copper production (Gorai et al., 2003). It is usually disposed in uncovered dumps in the vicinity of a copper smelter plant. Dumping or disposal of such large amounts of copper slag can cause environmental problems. According to Mihajlovic (2012), copper slag is classified as hazardous

(2011) reported that the main constituents of copper smelter slags found around the world are ...
A smelting plant in Bor extract copper from copper ores and copper concentrates by a pyro metallurgical process. During years of operation, a considerable amount of copper slag has been generated as a by-product and has been dumped. Copper contents in these slags are as high as 0.6 up to 0.8%.
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. ... The existing CS flotation circuit in the plant was used in 2016. In 2017, a ...
Chemical analysis of smelter slag sample obtained from Flotation plant in Bor, Serbia, showed that it contains 3.56% of copper, of which over 73% is in the sulphide form, as well as 0.58 g/t of gold and …
In this paper, the results of the study of application of thionocarbamates in copper slag flotation are presented. Chemical analysis of smelter slag sample obtained from Flotation plant in Bor, …
Factors affecting flotation of water-quenched slag from a copper smelting plant in Hubei province,such as grinding fineness,pulp density,pH value and the reagent system,were studied.The results indicate that the best flotation efficiency was obtained with a grinding fineness of 95%-0.074 mm,a pulp density of 30%,a pH value of 7.0 and reagent …

Flotation of silica and alumina from the slag improved bio‐leaching performance and recovered about 74.0% of copper, 60.0% of nickel and 33.4% cobalt in the bio‐leaching process conducted at ...
How to Recover Copper from Slag by Flotation. Table of Contents. The bulk of the world's output of copper is produced by smelting copper sulfide flotation …
The copper smelter slags are highly heterogeneous and chemically diverse (Table 2).The bulk chemical composition of copper slags mainly depends on the metallurgical processes from which they are derived, which are determined by type of concentrate, type of fluxes, type of furnaces and cooling rates (Gbor et al., 2000, 2003; …
The first campaign was carried out using an existing copper slag flotation circuit in the plant. During the second campaign (2017), a circuit for sulfide ore flotation with an additional columnar flotation cleaning stage was evaluated. ...

Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide.
The pyrometallurgical production of copper generates slags, a residue with a significant content of this metal. Copper can be recovered from the slags by froth flotation after cooling, crushing ...
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 ).
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …
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 …
The researchers reported that particle size, reagent type, reagent dosage and slurry pH are the significant operating variables governing the flotation of copper slag. …
From the World Copper Smelter Survey 2004 it can be estimated that at that time 37% of the smelters used electric furnaces for slag cleaning, 26% used …
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.
The copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper losses of most plants in the discarded slag limited between 0.8 wt.% and 1.0 wt.% (Coursol et al., 2012). However, the final copper slag still contains large amounts of valuable …
