Copper (Cu) particles volume fraction in Aluminum-Copper (Al-Cu) have been detected by multiple-amplitude modulation which is implemented into an impedance measurement system (mAM-IMS). The mAM-IMS has an evaluation section and a measurement section. The evaluation section is composed of three steps which are 1) The evaluation step of single modulation frequency f_m for Cu particles volume fraction φ_Cu detection in static Al-Cu mixtures, 2) The evaluation step of multiple f_m for φ_Cu detection in vibrating Al-Cu mixtures, 3) The determination step of multiple-AM for the best modulation and carrier frequencies f_m/f_c combination for φ_Cu detection in vibrating Al-Cu mixtures under vibration frequency f_p. All steps in the evaluation section are investigated by a simulation study. After the evaluation step, the best f_m/f_c combination is tested and evaluated in the measurement section by the wet-type gravity vibration separator (WGS) deck for the experimental φ_Cu detection in vibrating Al-Cu mixtures under constant vibration frequency f_p. As a result, the mAM-IMS with the best f_m/f_c combination should satisfy the requirement of f_m ≤ f_p ＜ f_c where f_c = 2.5f_p. By evaluating the normalized measured impedance Z′^^exp_m in the range of 0% ≤ φ_Cu ≤ 57.14%, the mAM-IMS with the best f_m/f_c combination is able to detect the experimental φ_Cu in vibrating Al-Cu mixtures by spatial-mean error deviation 〈ε〉=8.12%.
