Received: 11 December 2013; in revised form: 24 January 2014 / Accepted: 5 February 2014 / Published: 19 February 2014 Abstract: The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns. This has resulted in the generation of large quantities of electronic waste (e-waste) that needs to be managed. The handling of e-waste including combustion in incinerators, disposing in landfill or exporting overseas is no longer permitted due to environmental pollution and global legislations. Additionally, the presence of precious metals (PMs) makes e-waste recycling attractive economically. In this paper, current metallurgical processes for the extraction of metals from e-waste, including existing industrial routes, are reviewed. In the first part of this paper, the definition, composition and classifications of e-wastes are described. In the second part, separation of metals from e-waste using mechanical processing, hydrometallurgical and pyrometallurgical routes are critically analyzed.

He married and had eight children and was a converted Wesleyan Methodist. He manufactured and designed locomotives and other engines and worked with other significant railway individuals of the time, for example George and Robert Stephenson. He was responsible for manufacturing the first locomotive for Russia and British North America. It has been debated historically up to the present day whether Hackworth gained enough recognition for his work. Proponents of Hackworth have suggested that he invented of the ‘blast pipe’ which led to the success of locomotives over other forms of rail transport. His sons other relatives went on to be engineers. His eldest son, John Wesley Hackworth did a lot of work to promote his fathers memory after he died. His daughters, friends, grandchildren, great-grandchildren and ancestors to this day have worked to try and gain him a prominent place in railway history.

    Sir Lindsay Wood Born in 1834 at Killingworth Hall, Northumberland, he was the youngest son of Nicholas Wood, colliery owner and engineer who worked alongside George Stephenson during the early years of locomotive development as well as experimenting with a miners’ safety lamp. He was educated at Kepier Grammar School, Houghton-le-Spring and Kings College ,London. He served an apprenticeship as a mining engineer while working at the Hetton Collieries owned by the Hetton Coal Company. His father was manager of the Hetton Collieries and in 1858 Lindsay was appointed viewer (manager) of the North Hetton Colliery (Moorsley Pit). Shortly afterwards he became assistant to his father as manager of Hetton Collieries and when his father died in 1866 he became Managing Director of the Hetton Collieries which comprised the Lyons Colliery, Moorsley Colliery, the Hazard Pit as well as Eppleton and Elemore Collieries. He continued in this position until the company was sold in 1911 to Lord Joicey’s company. Lindsay Wood was married in 1873 to Emma Barrett of Heighington Hall near Darlington. They initially lived at Hetton Hall but moved to The Hermitage at Chester-le-Street. They had four sons and two daughters the eldest son being Mr. Arthur, Nicholas Lindsay Wood born in 1875. Mr Wood, like his father became a mining engineer and was also a captain in The Northumberland Artillery, a territorial regiment. In 1891 Mrs Emma Wood died suddenly in the late spring at the Hermitage, a great loss to the family. BY the 1870s Lindsay Wood was a managing partner in the North Hetton Coal Company as well as the Harton Coal Company.

  • Thermodynamic Studies of Liquid Au-Zn and Ag-Zn Systems
    Thermodynamic Studies of Liquid Au-Zn and Ag-Zn Systems By Akira Yazawa* and Alzbeta Gubcova** In order to clarify the basic principle of the Parkes process, in which precious metals are extracted from the crude lead by the addition of zinc, thermodynamic studies have been carried out for the liquid Au-Zn and Ag-Zn systems for which thermo- dynamic data have not been satisfactorily available. The electromotive force was measured using the following type of the cell: The error arising from volatilization of zinc was carefully avoided. The break points on the electromotive force curves against temperature suggest that the liquidus lines for the Au-Zn system recommended by Hansen are not acceptable, and that higher liquidus temperature may be reasonable. The activity curves obtained from the electromotive force values show considerably negative deviations from Raoult's law, especially in the Au-Zn system, suggesting the large affinity of zinc for gold and silver. In connection with the present data obtained, the properties of alloys between groups IB and II have been discussed in terms of the electronegativity, ionic radius and electron configurations. It is proved phenomenologically that the obtained data may be also interesting from the standpoint of recent stability theories of alloy phases. To understand the principle of the Parkes process, the results in the present study are combined with the data of the Au-Pb and Ag-Pb systems, and the free energy of mixing for the ternary Au-Pb-Zn and Ag-Pb-Zn systems has been calculated. Moreover, the removal limit of the precious metals from lead has been explained under the simplified assumptions.
