Feb 08 2017 Consequently flotation was attempted to recycle Cu in slag containing copper sulphide components Three key factors affecting flotation were ascertained namely grinding fineness the collector and the pH value while the recovery of Cu estimated by ICP and XRF Copper concentrate grading at 1447 with 7966 Cu recovery was obtained in the
Feb 08 2017 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 distribution in which bornite was the main copperbearing mineral after a detailed mineralogy analysis via polarizing microscope SEM and XRD
Oct 10 2015 The information will help in the flotation of copper smelter slag for better copper grade and recovery Abstract Present work focuses on the differences in the performances obtained in the froth flotation of copper smelter slag with multiple collector viz sodium isopropyl xanthate SIPX sodium diethyl dithiophosphate DTP and alkyl
Jan 01 2020 Slag cleaning can be divided into two types first being the pyrometallurgical reduction and settling of liquid slag which is performed in slagcleaning furnaces and the second type being the mineral processingbased slag cleaning of solidified or granulated slag by crushing andor grinding followed by gravity concentration or froth flotation
Feb 01 2007 The recovery of copper and cobalt from ancient copper slags from the K re region of Turkey was investigated A fayalitictype of ancient copper slag containing 124 Cu 053 Co and 5316 Fe were subjected to an experimental study Two different routes were followed to recover the metal values The first route was roasting the slag with pyrite followed by leaching
Optimization of the flotation of copper smelter slags from Namibia Custom Smelters Slag Mill Plant Elias Sipunga A research report submitted to the Faculty of Engineering and the Built Environment University of the Witwatersrand in partial fulfillment of the requirements for the degree of Master of Science in Engineering
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
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 This article focuses on industrial flotation which consisted of two oneyear campaigns
Flotation is an important technology to recover copper from copper slag There are a few industrial flotation facilities for treatment of copper slag such as Magma Copper San Manual facility USA Altonorte Flotation Plant Chile Outokumpu facility Finland

flotation of slag tailings using sulphuric acid solutions without or with the addition of either ferric sulphate or hydrogen peroxide However the maximum copper extraction attained with the slag was modest at about 63 whereas that obtained with the slag flotation tailings was as low as 33 Urosevic et al 2015 Accordingly the objective
Jan 01 2020 The copper content of the slags range between 08 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
Feb 01 2007 The second route was flotation of the slags roasting of the flotation tailings with pyrite and leaching The second route was found to be suitable for the treatment of the copper slag studied In the flotation step a copper concentrate containing approximately 11 Cu was produced with a 77 recovery while 93 of the cobalt stayed in the tailings
The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant Slag Mill Plant for liberation and recovery of copper This work focuses on optimizing the recovery of copper minerals in copper smelter slags by means of froth flotation
Guo et al 2016 developed a new technology to improve the beneficiation of copper and iron components from copper slag by modifying the molten slag to promote the mineralization and grain growth of the valuable compounds Results showed that under the proper conditions the copper grade of the rougher stage increased from 643 to 1104 the iron recovery of magnetic separation
Production of copper concentrate by flotation of smelter slag has started in 2001 Flotation concentrate goes to the Copepr Smelter once more for production of copper cathodes and the rough flotation tailings go to the flotation tailing dump Copper recoveries in the flotation process of smelter slag reaches the value of about 45 50

Feb 03 2021 Possibilities for minimizing copper losses in converter slags include 1 settling the molten slag to recover entrained matte and copper 2 smelting the slag with a suitable reductant to recover a copperiron alloy or a lowgrade matte 3 beneficiation of slags by magnetic separation and
Key words Converter slag flotation copper cobalt sulphurization 1 Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile and it is estimated that around 4 million tons of slag are disposed every year and another
Copper recoveries in the flotation process of smelter slag reaches the value of about 45 50 Slag in RTB plants is processed in a facility that is not designed for slag processing but it is only adapted to these conditions The obtained results are worser than the expected ones and testing that could improve them will continue This paper shows the way of obtaining the flotation concentrate of smelter slag
Based on the chemical compositions of the slag and the slag flotation tailings Table 1 it can be concluded that the copper dissolved from the slag flotation tailings mainly originates from the copper oxide phases about 10 wt which are not amenable to flotation Low copper extractions both from the slag and the slag flotation tailings
