“…Stringent legislation is being implemented across Europe relating to contamination from heavy metals in the environment. Forton et al 175 reported a method for the reliable determination of the Cu, Fe, Pb and Zn content of automotive shredder residue. The material was first pyrolysed in a rotary kiln to remove organic fractions so that different analytical methods (ICP-MS, EDXRF, WDXRF and PXRF) could be used to analyse the burned char, which varied from large fractions of metal to fine powder.…”

This annual review of X-ray fluorescence covers developments over the period 2007-2008 in instrumentation and detectors, matrix correction and spectrum analysis procedures, X-ray optics and micro-fluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications as assessed from the published literature. The trend set in previous years continues with an increase in the number of papers published on applications for XRF, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. Earlier literature has not been ignored in that some of Archimedes oldest writing, previously hidden from sight in a medieval prayer book has now been revealed thanks to the power of modern m-SRXRF. X-ray optics now benefit from the use of poly-capillaries systems, equipment portability has been extended to include the TXRF configuration and readers will find several papers on the use of both two and three dimensional imaging to support environmental, geological and biological studies.

“…But the conventional high temperature chloridising roasting is mainly used for processing high iron grade ores, and it heavily erodes equipment, especially rotary kilns (Li, 1992;Fraissler et al, 2009). Furthermore, reduction roasting in the rotary kiln is a significant method and has been successfully applied in industry to recycle lead and zinc from metallurgical solid wastes (Jiang et al, 2006;Forton et al, 2007). Reduction roasting is also an effective technology to improve the iron grade of blast furnace burden.…”

In this paper, a study of processing pyrite cinder and metallurgical slag using a 'one step' technology in strand grate-rotary kiln at a laboratory scale is presented, which aims to recover iron, lead, zinc and copper. The compressive strength of preheated pellets reached 527 N per pellet and the removal rates of copper, lead and zinc reached 36?36, 92?86 and 20?0% respectively, when the green balls were preheated at 1125uC for 10 min. Reduction of preheated pellets was followed, at the carbon/iron ratio of 3?0 and 1100uC, for the reduction time of 70 min, and the metallisation degree of 86?31%, the compressive strength of 1777 N per pellet and the copper, lead and zinc removal rates of 36?36, 99?12 and 71?00% were achieved respectively. These prereduced pellets with 80?58%Fe made from pyrite cinder and metallurgical slag can be widely applied to enhance the operation of blast furnace.

End-of-life vehicles (ELV) have become a global concern as automobiles have become popular worldwide. An international workshop was held to gather data and to discuss 3R policies and ELV recycling systems, their background and present situation, outcomes of related policies and programs, the framework of recycling and waste management, and case studies on related topics in several countries and regions, as well as the essential points of the comparison. Legislative ELV recycling systems are established in the EU, Japan, Korea, and China, while in the US, ELV recycling is managed under existing laws on environmental protection. Since automobile shredding residue (ASR) has a high calorific value and ash content, and includes heavy metals as well as a mass of unclassified fine particles, recycling ASR is considered highly difficult. Countries with a legislative ELV system commonly set a target for recovery rates, with many aiming for more than 95 % recovery. In order to reach this target, higher efficiency in ASR recovery is needed, in addition to material recycling of collectable components and metals. Environmentally friendly design was considered necessary at the planning and manufacturing stages, and the development of recycling systems and techniques in line with these changes are required for sound ELV management.
