The characterization of total and leachable metals in foundry molding sands.
Waste molding sands from the foundry industry have been successfully used as a component in manufactured soils, but concern over metal contamination must be addressed before many states will consider this beneficial use. Since there is little data available on this topic, the purpose of this study was to characterize total and leachable metals from waste molding sands. A total elemental analysi...
متن کاملIdentification of Significant Impact of Silicon Foundry Sands Mining on LCIA
This paper presents a case study based on a LCA (Life Cycle Assessment) research program of the silicon foundry sand (SFS) due to the large quantity of produced waste foundry sand (WFS). The foundry waste is a high priority sector within the growing European foundry industry. It is necessary to understand the full life cycle of the foundry waste in order to correctly identify magnitude and type...
متن کاملHarmless Treatment of Used Foundry Sands and Dewatered Municipal Sludge by Microwave
H. F. Wang, J. J. Lu, K. F. Chen, H. L. Duan, Wuhan Textile University, Wuhan, China A new method to treat four solid wastes of sodium silicate used sands, dewatered municipal sludge, clay sands sludge and waste polyethylene, was discussed. About wt/ 50 % sodium silicate used sands and wt/ 50 % dewatered sludge were mixed, and then cured by microwave with a certain thickness film of clay sands ...
متن کاملNew Bicomponent Binders for Foundry Moulding Sands Composed of Phenol-furfuryl Resin and Polycaprolactone
The aim of this article is to test the properties of foundry moulding sands with a new bicomponent organic binder. The new binder is the composition of phenol-furfuryl resin, commonly used in foundry practice and biodegradable material – polycaprolactone. The paper presents the research of strength properties, thermal destruction and thermal deformation of moulding sands with a new bicomponent ...
متن کاملUse of standardized procedures to evaluate metal leaching from waste foundry sands.
As part of the casting process, foundries create sand molds and cores to hold the molten metal to specific dimensional tolerances. Although most of the waste foundry sands (WFSs) from this process are land filled, there is great interest in diverting them for use in agricultural and geotechnical applications. One potential limitation to their beneficial use is concern that the WFSs will leach h...
