  • The recovery of copper from a copper mine effluent in a hybrid flotation/microfiltration cell

    A new hybrid process for cleaning wastewater, combining flotation and membrane microfiltration, was investigated. The hybrid process combined the advantages of both flotation and membrane separation: the flotation cell removed a large proportion of suspended solid particles, while the membrane module produced clean water permeate effluent. The hybrid cell performance has been studied in depth and ...

  • Recovery of Copper From Automotive Wiring Harnesses

    Auto manufacturers have set a goal for the technical recyclability and recovery of new vehicles that calls for as much as 95% of the vehicle weight to be diverted from landfill in a technically and economically feasible manner. In order that future vehicles achieve this goal, which is in line with the draft European Union End-of-Life Scrap Vehicle Directive, it will be necessary to develop a ...


  • Sequential recovery of copper and nickel from wastewater without net energy input

    A novel bioelectrochemical system (BES) was designed to recover copper and nickel from wastewater sequentially. The BES has two chambers separated by a bipolar membrane and two cathodes. Firstly, the copper ions were reduced on a graphite cathode with electricity output, and then with an additional bias-potential applied, the nickel ions were recovered sequentially on a copper sheet with ...

  • Optimizing the recovery of copper from electroplating rinse bath solution by hollow fiber membrane

    This study aimed to recover and remove copper from industrial model wastewater solution by non-dispersive solvent extraction (NDSX). Two mathematical models were developed to simulate the performance of an integrated extraction–stripping process, based on the use of hollow fiber contactors using the response surface method. The models allow one to predict the time dependent efficiencies ...

  • The use of step and pulse tests to design activated carbon adsorption columns for recovery of copper ions from aqueous industrial effluents

    Dynamic experiments were carried out on the adsorption of copper ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a conventional heterogeneous model of the activated carbon bed, assuming a Langmuir adsorption isotherm. Bed depth had little effect on ...

  • The Comparison between Two Kinds of Copper Cable Granulators

    Copper cable granulator, also named scrap wire recycling equipment, is a machine used for crushing copper scrap and later separating copper from the plastic. It belongs to environmental protection equipment. The current copper cable granulator is generally divided into two kinds: dry-type copper wire granulator and wet-type copper wire granulator. What merits and demerits do they have? ...

  • Flotation of copper residues with high oxidation and combination ratios

    Sulphidising flotation was employed to successfully recover copper residues with high oxidation and combination ratios and the main components of the mineral chrysocolla (CuSiO3). Sodium sulphide (Na2S), ammonium sulphate ((NH4) ...

  • Copper Smelting Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Microbiological leaching of chalcopyrite: an environmentally sound approach to processing a sulphide copper concentrate

    Mineral sulphides are the main source of copper, from which this metal is recovered by pyrometallurgical processing after a flotation procedure. These processes generate high emissions of SO2 gases, which, in many cases, are discharged into the environment. The bioleaching method had been successfully used in copper recovery from low grade and secondary sulphide ores. Only recently, has it ...

  • Control of Copper Electrolyte impurities using short bed ion exchange

    Abstract; This paper discusses the short bed ion exchange process for the removal of metal contaminants from copper electrolyte bleed streams. Processes for the selective removal of sulfuric acid, nickel, arsenic, antimony, bismuth, and iron will be discussed. Considerable importance is given in controlling nickel and iron content in electrolyte by adopting the short bed ion exchange process for ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Evaluation of microbial population and attachment study during bio–heap leaching at Malanjkhand copper project

    Microbial analysis of a 2X1000–tonne bio–heap leaching plant of Malanjkhand copper ore was done. Continuous monitoring of the micro–organism profile was done through conventional methods. The evolution of microbial population was done at quarterly intervals. The bacterial cultures were allowed to grow on Feo medium and FeSo medium. Three iron–oxidising acidophiles, namely, ...

  • Removal of copper and lead ions from aqueous solutions by adsorbent derived from sewage sludge

    Adsorbent prepared from sewage sludge has been used for the adsorption of Cu2+ and Pb2+ from aqueous solutions. It was noted that an increase in removal efficiency achieved 72% and 56% when agitation time achieved 120 min, and a decrease in the removal efficiency from 81% and 70% to 36% and 40% when the heavy metals initial concentration from 10 mg L ...

  • Removal of copper ions from aqueous solution by the sodium salt of the maleic acid-allylpropionate-styrene terpolymer

    The sodium salt of the maleic acid-allylpropionate-styrene terpolymer was used for recovery of copper ions from aqueous solution. Effects of contact time, sorbent weight and initial Cu2+ ion concentrations on removal efficiency were tested. The maximum experimental sorption capacity of the sorbent for copper ions is 0.71 g g−1. The sorption isotherm of copper ions onto a prepared polymer ...
