  • Is it time to recycle more nickel?

    Now you might think me a little sad, but I have to confess that as a metallurgist, I always find it interesting just how closely the history of mankind is linked to advances in metal working. The first evidence of metal working in Europe dates from around 5500 BC with the extraction of copper, lead and precious metals and this was followed by the working of bronze from around 4000 BC, both of ...

  • Nickel salt recovery using Recoflo short bed ion exchange

    Since its commercialization over thirty years ago, the Recoflo® short bed ion exchange process has been extensively utilized for recovery of a wide variety of acids and metal salts. The process has a number of unique features such as utilization of fine mesh resins in a compressed bed, typically 12 – 24 inches in height, which together make it ideal for these types of applications. With ...

  • Recovery of nickel from spent catalyst by single- and multi-stage leaching process

    Nickel-supported catalyst is used in petroleum, fertiliser and iron industries. This research studied the possibility of recovering nickel by leaching the ground catalyst with sulphuric acid. The leaching was done in single stage and multi-stages. The results obtained in single-stage leaching showed that the percentage recovery of nickel increased with increasing acid concentration used up to 25% ...

  • 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 ...

  • 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 ...


  • Metal Recovery in Electroplating: Email Ltd, Kitchen and Bathroom Products Division

     The Dorf Design division of Email Kitchen and Bathroom Products Pty Ltd have installed electrolytic recovery equipment on their drag-out tanks of nickel and gold plating lines, and replaced chrome with hydrogen peroxide in the bright dipping process. The total capital cost of these initiatives was $67,800, with annual savings of between $43,190 - $50,190 per annum. This represents a payback ...


  • Aqua Regia Digestion for Trace Metals Recovery from Soil and Water

    Metals are regulated because they have the potential to harm human health and the environment. Unlike organic chemicals, metals are not degradable and have a greater tendency to accumulate. According to Environmental Protection Agency metals and metalloids of primary interest are: Silver (Ag), Aluminium (Al), Arsenic (As), Boron (B), Barium (Ba), Beryllium (Be), Cadmium (Cd), Cobalt (Co), ...

  • Metal removal and recovery from process solutions using short bed ion exchange

    Ion exchange has historically proven, in certain applications, to be an effective method for the metal finishers to minimize waste, ensure effluent compliance, provide water recycle, and even produce a concentrate suitable for recycle back to the process bath. One of the more interesting innovations in ion exchange technology over the past few decades has been the Recoflo short bed ion exchange ...

  • Bioremoval of toxic metals from aqueous mixtures and recovery of biomass by dispersed-air flotation

    In the present paper the solid/liquid separation of suspended, metals-loaded biomass was mainly studied by successfully applying flotation. Industrial non-living biomass samples of different origins have been tried in the laboratory as sorbents of metal ions, with particular emphasis on Streptomyces rimosus, an effective for this purpose biomass. Dispersed-air flotation was used as the harvesting ...

  • 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 ...

  • Removal of Ni(II) from electroplating rinse waters using cation-exchange resins: batch and column studies

    The adsorption of Ni (II) from nickel electro plating rinse water has been attempted. Indion 225 and Dueolite C 20 cation-exchange resins through batch and column mode for the recovery of Ni (II), which showed a remarkable increase in sorption capacity. On the basis of isotherm analysis, more efficient adsorbent is chosen for column mode adsorption studies. The continuous-flow study was to ...

  • Separation of finely dispersed sorbents from purified water by ultra-flocculation and turbulent micro-flotation

    This paper describes studies of the process of recovery of finely dispersed sorbents from water by means of ultra-flocculation, sedimentation and turbulent micro-flotation, and the sequential combination of these steps. With reference to the most commonly used finely dispersed sorbents in the purification of water from organic contaminants, heavy metals and radio nuclides (aluminium hydroxide, ...

  • ACID SEPARATION FOR IMPURITY CONTROL AND ACID RECYCLE USING SHORT BED ION EXCHANGE

    Acid separation using short bed ion exchange is a now well established technology in copper refinery tankhouses. Refinery bleed streams from liberator cells are treated by short bed systems to produce an acid-free byproduct stream that contains the bleed metals and valuable nickel salts. Removing the acid eliminates the need for a black acid evaporator and reduces the amount of sodium carbonate ...

  • Improvement of the Caenorhabditis elegans growth and reproduction test to assess the ecotoxicity of soils and complex matrices

    A growth and reproduction test using the nematode Caenorhabditis elegans was recently standardized by the International Organization for Standardization. Performing the ISO 10872 protocol (2010) revealed some drawbacks when applied to soil or soil mixed with complex matrices. We propose some modifications to the current protocol in order to normalize the test conditions. An appropriate range ...
