摘要：The purpose of this paper was to measure the leaching efficiency for a termostated column designed to extract metals in muds originated by foundry processes. The results obtained were useful to contemplate different alternatives helping to solve the problem of stocking enormous volumes of polluted sand produced by industries. Samples of residual sands and muds (treated sands) comingfrana an engine factory and horn a termostated column respmtively, were irradiated using an externa1 beam of 3.55 MeV energy protons. From the quantitative analysis PIXE (Proton Induced X-ray Emission), it was posible to-establish the level of pollution in sands due to the foundry processes and to evaluate the leaching efficiency of the output liquid pbase from the termostated column. For polluted sands, certain cases were observed for which the eficiency was not enough to decrease the level of pollution in, e.g., Cu, Zn, Br y Pb.
