Abstract
The main goal of this paper is to present a new approach to evaluate the recovered conductive granular waste purity. For this purpose, the eddy current approach which is commonly applied in nondestructive evaluation has been used. The experimental tests consist of several samples composed of copper particles mixed with sand inserted in a cylindrical container with solenoidal coil. The impedance of the coil is measured, using precision LRC-meter, for several frequencies per sample and used according to the Experiment Design Methodology (EDM) to determinate the relationship between input and output of experiments, to have a quadratic model that will be used for inversion. The input and output are successively impedance and percentage of copper particles contained in the container. The results show the capability of the proposed approach to evaluate the conductive recovered waste purity.
