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 ...

Meanwhile, the high-grade nickel market saw a moderate deficit as evidenced by a decline in total nickel inventories of the LME and SHFE, which dropped by 49 kt in 2022 to 58 kt at the end of the year, or less than 10 days of global consumption. ... Nickel ore imports from the Philippines were down due to bad weather conditions, which kept ore ...

A novel method of high-grade ferronickel production was developed using self-reduction and selective oxidation. • Oxidation by CO 2 at a concentration of 70 vol% allowed for a nickel recovery >95% and grade of ~32 wt%.. Metallic nickel and iron were separated by selective oxidation with CO 2, and CO 2 was efficiently utilised.
