Abstract: A method for recovering metallic materials from crystalline silicon photovoltaic modules. The method includes removing aluminium frames and junction boxes from the photovoltaic modules to provide photovoltaic sandwich structures. The method further includes shredding the photovoltaic sandwich structures to form photovoltaic sandwich structure particles and electrostatically separating the photovoltaic sandwich structure particles into a first fraction and a second fraction with an electrostatic separator. The method further includes feeding at least a portion of the second fraction to an electrostatic separator for one or more subsequent electrostatic separations into the first and second fractions, wherein the first fraction includes less than 5 percent by weight of total polymer particles and is substantially free of glass particles.
