2019-9-1  Nickel is upgraded by 17% and 36% for ore S and I, respectively. There is no change in the nickel grade of ore L using the Falcon, similarly to what was obtained using the magnetic separation. The XRD analysis of the light fraction of the Falcon concentrator for the ore S and I samples is presented in Fig. 4. It seems that both particle size and particle density are affecting the separation using the
