Process of separating gold from copper anod

Mar 01, 2014 The current work attempts to study the recovery of gold from copper anode slime by means of a novel process utilizing magnetite nanoparticles (MNPs). In this process, MNPs were first synthesized by the co-precipitation method, and the characterization of the product was then carried out using the X-ray diffraction (XRD), transmission electron

    Recovery of Silver and Gold from Copper Anode Slimes

    Sep 11, 2014 1. Roasting. Copper anode slimes are roasted at 600–800 C with sulfuric acid or oxygen, which depends on the composition of slimes. During the process, selenium is evaporated in the form of SeO 2 gas. Copper is present in the form of soluble copper sulfate, which can be removed with dilute acid or water leaching. 2

    Process for the Recovery of Gold from Anode Slimes

    Aug 15, 2013 The smelting stage of the copper producing process produces a copper anode which is typically three hundred plus pounds and 98+ percent copper. These anodes contain, among other elements, various metals some of which are quite valuable. In order to separate these other elements from the copper, these anodes are placed into a tank (or

    May 22, 2018 You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off
