Abstract. Skeletal molybdenum/calcium ([Mo]/[Ca]) shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49 • N). These ratios were determined by quantitative LA-ICP-MS analyses of daily striae taken every third day (i.e. a temporal resolution of 3 days) in 36 flat valves (2-years old; 3 shells/year). Variations of ([Mo]/[Ca]) shell ratios were significant and reproducible for scallops from the same population, from different years (1998)(1999)(2000)(2001)(2002)(2003)(2004)

a b s t r a c tThis paper reviews the tools and methodologies used for incorporating sustainability considerations into the design of mineral processing operations. It was found that while there is a range of tools and methodologies that contribute to Design for Sustainability, there is no consistent, integrated approach to support the mineral industry in incorporating a greater level of sustainability into the design process. This paper identifies the required elements in such an approach and discusses the ways in which its development would progress the industry towards sustainability.

“…Molybdenum is mainly used in metallurgical applications as an alloying element in the production of stainless steel or castiron alloys (Barceloux 1999), and in the production of flame retardants, pigments and catalysts for high temperature chemical processes. The molybdate ion MoO 4 2-, the most common oxyanion of molybdenum, occurs in various types of wastewaters, like wastewater from a styrene monomer plant (1000 mg/l) (Swinkels et al, 2004), scrubber effluent of a municipal solid waste incinerator (0.95 mg/l) (Lievens et al, 2010) and mining water (, 0.1 to 2.2 mg/l) (Dessouki et al, 2005;Panayotova and Panayotov, 2004;Rojas and Vandecasteele, 2007). Traditional industrial wastewater treatment plants remove cations (e.g.…”

“…At high concentrations, oxyanions can be precipitated as their Ca-metalates, but this usually leaves rather high residual concentrations (Swinkels et al, 2004). Adsorption on goethite (a-FeOOH) and akageneite (b-FeOOH), is efficient for the removal of different oxyanions at low concentrations (Rovira et al, 2008Watkins et al, 2006;Wainipee et al, 2010).…”

Industrial wastewater may contain high molybdenum concentrations, making treatment before discharge necessary. In this paper, the removal of molybdate anions from water is presented, using clinoptilolite zeolite coated with magnetite nanoparticles. In batch experiments the influence of pH, ionic strength, possible interfering (oxy)anions, temperature and contact time is investigated. Besides determination of kinetic parameters and adsorption isotherms, thermodynamic modeling is performed to get better insight into the adsorption mechanism; molybdenum is assumed to be adsorbed as a FeOMoO 2 (OH).2H 2 O inner-sphere complex. At the optimum pH of 3, the adsorption capacity is around 18 mg molybdenum per gram adsorbent. The ionic strength of the solution has no influence on the adsorption capacity. Other anions, added to the molybdenum solution in at least a tenfold excess, only have a minor influence on the adsorption of molybdenum, with the exception of phosphate. Adsorption increases when temperature is increased. It is demonstrated that the adsorbent can be used to remove molybdenum from industrial wastewater streams, and that the limitations set by the World Health Organization (residual concentration of 70 lg/l Mo) can easily be met.
