  • Analysis of the Present Copper Recycling Market

    With the development of our economy, the copper recycling market sees a rapid growth. Now 1/3 of the copper consumption comes from the recycle of the copper scrap, therefore the recycle and status of the transaction of the copper will produce greater influence on the whole copper market in the future. Meanwhile, as the construction of the circular economy has been continuously getting ...

  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • EDXRF Analysis of Lead, Cadmium, Silver, Copper in Lead-Free Solder Materials

    X-ray fluorescence analysis can be used to quickly and easily analyze samples in solid, powder, and liquid states nondestructively, and is therefore widely used as a screening technique for compliance with the RoHS/ELV directives. A large amount of lead-free solder is used for surface-mount circuit boards. Here we evaluated the sensitivity of analysis of Pb, Cd, Ag, and Cu in lead-free solder ...

  • Analysis of chromium and copper by cathodic stripping voltammetry with mixed ligands

    Abstract Cathodic adsorptive stripping voltammetry is one of the most sensitive analytical methods for ultratrace analysis. The detection limit is usually lower than 10 -9 mol/L. Most adsorptive stripping procedures have been focused on the one ligand/one analyte approach. In order to reduce analysis time and sample volume, the possibility of simultaneously determining several metals by cathodic ...

  • Copper distributed by Atx1 is available to copper amine oxidase 1 in schizosaccharomyces pombe

    Copper amine oxidases (CAOs) have been proposed to be involved in the metabolism of xenobiotic and biogenic amines. The requirement for copper is absolute for their activity. In the fission yeast Schizosaccharomyces pombe, cao1+ and cao2+ genes are predicted to encode members of the CAO family. While both genes are expressed in wild-type cells, we determined that the expression of only cao1+ but ...

  • Surface Decontamination of Copper Compounds (Copper (elemental), Copper (I) Oxide) by DeconGel 1101

    Abstract Surface decontamination efficacy determination of DeconGel 1101 on stainless steel, carbon steel, concrete, Lexan, and rubber surfaces contaminated with elemental copper and copper (I) oxide (Cu2O) was performed with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) according to Environmental Protection Agency (EPA) SW-846 Methods: 3005A (sampling) and 6010C ...

  • Assessment of the ecological sustainability of pyrometallurgical copper extraction

    The present investigation is an attempt at assessing the ecological sustainability of one of the most popular technologies for pyrometallurgical copper production, namely Outokumpu's flash smelting method. The real operating installation in Umicore-Pirdop, Bulgaria has served as a model flowchart. The assessment has been made using the exergy method of thermodynamic analysis. The exergy of ...

  • Impact of plumbing age on copper levels in drinking water

    Theory and practical experiences suggest that higher copper levels in drinking water tap samples are typically associated with newer plumbing systems, and levels decrease with increasing plumbing age. Past researchers have developed a conceptual model to explain the ‘aging effect’ founded in the proposed evolution of copper(II) corrosion by-products on the pipe surface, based on theoretical ...

  • Comparison and analysis of burden design methods in blasting: a case study on Sungun copper mine in Iran

    In this study, 19 burden designing methods have been analysed for burden design in the Sungun Copper Mine in Iran. Also, economical Optimum Burdens (OBs) have been calculated using the results of actual blastings. The results of mentioned methods and optimum burden have been compared with each other. The comparison shows that the Anderson, Pears, Allsman, Langefors and Energy Transition (ET) ...

  • SENSPOL evaluation of Cadmium, Lead and Copper onsite monitoring of water and soil samples

    This study details the onsite analysis of water and soil samples from 5 different locations in germany using the PDV6000plus and contains comparison data with Graphite Furnace Atomic Absorption ...

  • Study of key factors in geometrical and grade modelling of copper porphyry deposits

    Despite the development of a series of remarkable modelling technologies and sophisticated commercial software packages in the past two decades, the modelling process and software application are technically and practically facing a number of challenging issues. Some challenges are related to the theory and algorithm of modelling, and some of them related to the uncertainty of data. There is also ...

  • Copper status of exposed microorganisms influences susceptibility to metallic nanoparticles

    Although interactions of metallic nanoparticles (NP) with various microorganisms have been previously explored, few studies have examined how metal sensitivity impacts NP toxicity. Herein, we investigated the effects of copper nanoparticles' (Cu‐NPs) exposure to the model alga, Chlamydomonas reinhardtii, in the presence and absence of the essential micronutrient copper. The toxic ranges for ...

  • Effects of current density on copper nanoparticle prepared by electrochemical method

    Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
