Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

A comparative study of flash smelting furnace (FSF) slag and its flotation products (concentrate and tailing) reveals the factors affecting the separation of copper and arsenic in the ...

This article outlines and compares the different slag-cleaning systems that are currently in operation in the Chilean smelters, their strategies, the equipment in use, and their experiences.

Taking into account that the slag contained more copper than ore, a series of flotation tests was conducted on copper smelting slag produced in an electric furnace of …

Thus, implementing technologies of slag treatment is a complex and challenging task. Within this paper, application options, the environmental behavior, and …

The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment. Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper.

Copper slag has long been the subject of metal recovery. However, it has become apparent that copper slag flotation tailings can meet resource requirements under certain circumstances.

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 ...

Increasing the efficiency of metal in the new Bor smelter by 93 to 98 percent will contribute to the economic profit of the company, and one of the essential phase that RTB Bor will lead to higher metallurgical efficiency, and thus to greater profits, represents the processing of copper slag by flotation.

The beneficiation of copper slag employing gravity concentration and froth flotation, with particular emphasis on different collector systems, has been reviewed …

During the copper smelting process, it is common for a certain amount of copper to be lost to slag. In order to minimise this loss, the slag is further treated to recover the valuable metal. One treatment …

A series of laboratory batch flotation tests was conducted on a suite of calcium-ferrite-based slags made in continuous pilot plant smelting trials. The smelting tests were conducted as part of a ...

Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and …

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.

In this study, a sodium carbonate combined with mechanical activation enhanced flotation for recovering copper from copper slag was developed. Based on the phase analysis, the flotation experiment was conducted.

The first route was roasting the slag with pyrite followed by leaching. The second route was flotation of the slags, roasting of the flotation tailings with pyrite and leaching.

It has been estimated that for every ton of copper produced, approximately 2.2–2.5 tons of slag is generated as a result of the relatively low grades of copper concentrates now available. 2 There are several copper smelting plants throughout the world, and this has resulted in the production of approximately 40 million tons per year …

The efficiency of a flotation circuit operation relies on several factors that are pertinent to mineral nature and structure (variability of ore feed, particle size, complex mineralogy, and morphology) as well as the type of instrumentation and operational parameters (design parameters, reagents, quality of process water, air flow rate, and ...

Due to their relatively high average copper content (about 1.5 wt%), a mineral processing plant based on the flotation process has recently been established to produce thousands of tons of Cu-sulfide concentrate after slag crushing and …

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.

A series of laboratory batch flotation tests was conducted on a suite of calcium-ferrite-based slags made in continuous pilot plant smelting trials. The smelting tests were conducted as part of a wider CSIRO Minerals' research project aimed at developing a single-stage continuous copper making process.

Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly …

A comprehensive review of the methods of copper recovery from slags is presented by Kundu et al. [38], where the authors compare the efficiency and environmental impact of methods of flotation ...

The recovery of copper from smelter slag using flotation approach was studied (Fan et al., 2017). Three key factors affecting the flotation process such as grinding fineness, collector dosage, and ...

Various methods for the recovery of copper and other precious metals from this byproduct have been studied, and there are many operating flotation plants in industrial scale.

The present article attempts to review important research carried out in this direction. The beneficiation of copper slag employing gravity concentration and froth flotation, with particular emphasis on different collector …
