Product Description
Electrometallurgical refining of copper plays a significant role in the production of high purity copper metal and in the recycling of copper. Once again this importance is reflected in the electrorefining papers presented in the Copper 2007-Cobre 2007 Conference. A comprehensive survey of the industry indicates the continued adoption of permanent cathode technology, the use of anode preparation machines and polymer concrete cells, and the application of electrode handling automation and more advanced wireless process control. Project activity in copper electrorefining continues at a strong pace, with several existing facilities being modernized and/or expanded (notably in Japan and China) and new greenfields refineries being proposed (notably in China). The many industrial refining papers in this volume are complemented by a suite of strong fundamental presentations which discuss reagents, cathode quality and refining process modeling. A significant percentage of the world's cathode copper is produced by the leach-solvent extraction-electrowinning processing route. Another comprehensive survey of the copper EW industry indicates the continued adoption of automated electrode handling, permanent cathode technology, larger electrode sizes and higher current densities. Overall these trends have further resulted in improved tank house productivities and improved electrowon cathode purity. Project activity in copper electrownning greenfields projects is centered on central Africa, in particular Zambia and the DRC. Like the refining papers in this volume the many industrial manuscripts are complemented by a collection of fundamental presentations that discuss modeling and cathode quality. Overall, the 49 electrorefining and electrowinning papers of Copper 2007-Cobre 2007 provide a valuable record of the present status of the industry and summarize the research and development work being carried out in support of the industry. ...

Description:
The Loch of Clickimin, Shetland, is well known for its broch and associated monuments supposedly of the Bronze and Iron Ages, although the former date is disputed. Pollen, diatom and sedimentological investigations permit fresh insights into the landscape and economic impacts of those who constructed the monuments, reveal that the environs of the site experienced environmental change from Neolithic times onward and provide the first Holocene radiocarbon dates from the immediate locality. The broch-building period witnessed a continuation of pre-existing pastoral husbandry for which heather burning may have exacerbated the natural spread of blanket peat. Initially, no evidence was adduced for local arable activity in the present investigation, and this was thought to be consistent possibly with the low numbers of excavated querns and the absence of cereal macrofossil finds when compared with other Shetland broch sites. The application of 'rapid scanning' techniques, however, led to the discovery of a consistent cereal-type pollen representation from Bronze Age times onwards. The discrepancies between the palaeoenvironmental evidence and the environmental and palaeoeconomic inferences made by the excavator of the site are explored. Evidence is presented that both supports and contradicts previous assumptions surrounding an important archaeological site. ... Read more
