    Results of an extensive analysis of the abundance, shape and liberation grade of the aluminum and copper particles present in the incineration bottom ash (IBA) fine fraction, up to 2 millimeters, from a municipal solid waste incineration plant is presented. The total amount of aluminum and copper related to the IBA particle size fraction have been analyzed in order to propose different possibilities of separation technology for their recovery.
    It is shown that the aluminum content, 1655 grams per ton, is considerably higher than copper content (610 grams per ton). The amounts of metals are unequally distributed in the residue: more than 75% wt. of copper and 55%wt. of aluminum are in the fine fraction between 0.1 to 1.0 millimeters. Compared with aluminum, the shape of copper grains has a bigger ellipse ratio (the maximum height/width ratio of a grain) and they are the least liberated. In addition, no copper grains bigger than 1 millimeter were detected.
    This big amount of non-ferrous metals makes its recovery a profitable industry. According to the parameters analyzed and the physicochemical properties of these non-ferrous metals, electrostatic technologies are suitable to produce a high purity non-ferrous metals fraction, in addition, gravimetric concentration systems could be used for copper pre-concentration or separation and recovery of high purity non-ferrous metals fractions.
