  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • BlueOak - Precious metal recovery from electronics waste - Case Study

    The Challenge In the US, consumers alone dispose of some 3.2 million tonnes of e-waste annually; more than 80% of this ends up as waste, contributing >70% of all toxic metals in U.S. landfills. In a bid to tackle this wastage, BlueOak Resources. USA announced in July 2014 that they had selected Tetronics' technology for their national project to sustainably recover precious ...

  • E-scrap: metals too precious to ignore

    Increased recovery of waste electrical and electronic equipment (WEEE) is providing the global recycling industry with fresh challenges. Researchers from Berlin’s University of Technology have been taking a close look at the material flowing into and out of the recycling process, paying special attention to the precious metals content. Their main conclusion is that conventional sorting ...

  • Duncan recyling & refining - Precious metal recovery from spent catalysts case study

    The Challenge Spent catalysts contain Precious Metals, specifically the Platinum Group Metals (PGMs) that are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction/refining from primary sources. Duncan Refining and Recycling's (DR2) President, David Nichols, made the decision to ...

  • WEEE – aren’t materials too precious to lose?

    Chris Oldfield, managing director of UNTHA UK, was interviewed by leading journal MRW magazine recently, on the subject of WEEE. Drawing upon his specialist industry insight he commented on the methodology used to process WEEE and the extent to which the sector needs to go ‘back to basics’ to ensure precious materials are not lost. Conversation surrounding recyclate quality has ...

  • Platinum group metal recovery from spent catalysts case study

    The Challenge Catalyst wastes, including automotive catalytic converters and industrial catalysts, contain Precious Metals and specifically Platinum Group Metals (PGMs), which are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction and refining from primary sources. Furuya Metal Co. Ltd., ...

  • Phoenix county metals case study

    With their order placed before the instrument was officially available, Phoenix County Metals quickly benefited from their new Thermo Scientific Niton XL2 handheld XRF analyser. The robust Niton XL2 has proven ideal for Phoenix’s application, which involves the identification of gold, silver, platinum, palladium and rhodium from waste materials and products. Phoenix is a specialist ...

  • 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 ...


  • Recovery of Ruthenium and Other PGMs from Spent Petrochemical Catalysts

    The recovery of platinum group metals from spent petrochemical catalysts has economic benefits by the protection of the supply chain of these valuable and rare metals, thereby helping to create a sustainable value chain in the petrochemical industry for catalysts. Introduction The platinum group metals (PGMs) are used extensively in catalysts for the petrochemical industry owing to ...

  • A direct method for ultrafine gold networks with nanometre scale ligaments

    Preparation of precious metals into porous structures in nanoscale regime is currently only achieved by dealloying processes, in which a second or third component is leached out of matrices of metal alloys. To avoid loss and hassle of recovery of leached precious metals, direct synthetic methods should be developed. In this work, we report our chemical synthesis of ultrafine gold networks through ...

  • We Created the Technosphere, but is it the Birth Place of the Circular Economy

    Human activity has created the ‘technosphere’, a landscape which is composed of the materials we have developed, created and thrown away. Far from being a miserable landscape that may initially come to mind, like the desolate garbage filled scene in WALL-E, it could actually be the basis on which we can create a more sustainable way of managing our resources. Just like we have ...

  • Electronic Waste: The Rich Resource in the Urban Mine

    Forgetting your mobile phone can be a real pain, playing on your mind during the day. Then as you think you can feel your phone vibrating in your pocket and you come to realise how dependent we are on our gadgets. Electrical equipment has changed our lives completely and we rely on phones, microwaves, TVs, kettles, computers to keep us informed, entertained and even alive. It is hard to imagine ...

  • 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 ...

  • Case study: Mechano-chemical grinding

    Challenge Traditional grinding mills reclaim only a fraction of precious metals from ore, leaving valuable material in the tailings. These minerals are more difficult to liberate, as it requires the ore to be ground to a very fine mesh.
