  • Recovery of Precious and Secondary Metals from

    Recovery of Precious and Secondary Metals from Electrolytic Copper Refining (New York Meeting, February. 1934) MOST modern electrolytic copper refineries have found it expedient to build and operate a complete secondaries plant for the treatment of the electrolytic slime accumulated in the cells during the corrosion of the copper anodes.

  • Recycling of Copper

    Secondary copper can be used for the manufacture of these materials, though still within stipulated quality limits for impurities. Where scrap copper is associated with other materials, for example after having been tinned or soldered, it will frequently be more economic to take advantage of such contamination than try to remove it by refining.

  • Copper Scrap an overview ScienceDirect Topics

    Recycling of copper is based on a large variety of raw materials, ranging from low-grade copper scrap containing only a few percent Cu to very high-grade copper as well as pure copper close to 100% Cu (Table 7.1). Thus there are several options for recycling processes, within both primary plants and secondary plants treating only scrap material.

  • IsaKidd refining technology Wikipedia

    Prior to the development of the Isa Process technology, the standard approach was to use a starter sheet of high-purity copper as the initial cathode. These starter sheets are produced in special electrolytic cells by electrodeposition of copper for 24 hours onto a plate made of copper coated with oil (or treated with other similar face-separation materials) or of titanium.

  • Copper Smelting an overview ScienceDirect Topics

    W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching “oxide” and supergene sulfide

  • Copper Mining and Extraction: Oxide Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
