  • Volumetric Analysis & Three-Dimensional Visualization of Industrial Mineral Deposits

    Abstract Base and precious metal deposits are typically characterized by a single parameter such as the total weight of mineable gold. Industrial mineral deposits, on the other hand, are characterized by their end-use. For example, the volumetric evaluation of a limestone deposit depends upon who’s buying the product. The concrete industry has a suite of evaluation parameters such as ...

  • 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 ...

  • 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 ...

  • Method of low temperature pyrolysis as an answer for PCBs utilization.

    When people buy new computers, TV-sets or trendy mobile phones they do not think much about the future of substituted models. In a consumer society where devices are changed due to their obsolescence rather than break down the problem of pollution by e-wastes becomes more relevant. Disposal of printed circuit ...

  • Used to Useful

    Thanks to Mother Earth for giving us millions of tons of natural resources for our need & greed. After extraction & converting these resources in to products for our requirement, we forget to pay attention to recycle the used products but continue to extract afresh as if, nature has no right to say no. In the process, we attract natural calamities (natural recycling) to balance the ...

  • 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 ...

  • Advanced Threeway Catalysts

    One area of catalyst system design which has received relatively little attention is the method of application of precious metal, specifically with regard to its positioning in the catalyst. Recent advances in catalyst coating technology have enabled both washcoat and precious metals to be distributed inhomogeneously (zoned) along the length of a catalyst monolith. With the option of zone coating ...
