  • Comprehensive Characterization of Spent Chemical Foundry

    The presence of chromite, occasionally used in foundries as a replacement for siliceous sand or in the production of chromium, was confirmed by XRD and SEM–EDS analyses. With the hardness of aluminum and chromite being of 5 to 6 on the Mohs scale and therefore lower than that of silica (7), the question arises as to their influence on the

  • Foundry Sand

    4.1 Introduction. Used foundry sand (UFS) (Fig. 4.1) is a discarded material coming from ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal-casting industry to create molds and cores. About 1 ton of foundry sand for each ton of iron or steel casting produced is used ( Siddique and Noumowec, 2008 ).
