• A New Process for Cobalt Nickel Separation

    removes most of the deleterious impurities, and thus produces a nickel-cobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way; however, not all sulphide ores remaining today are suitable for this route.

    Nickel Wikipedia

    Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of

    Electronic structure of nickel, iron, and cobalt

    We present theoretical results for the electronic structure of nickel, iron, and cobalt impurities in MgO, calculated using a linear muffin-tin-orbital Green's-function method. We investigate the ground states and the localization properties of these defects, where lattice relaxations are not taken into account. With the help of a method from Fazzio, Caldas, and Zunger we analyze the optical

    Relaxation rates of 101 Ru in Ni and of 51 V and 103 Rh in Co were measured in high external field. Our results and the published results on 55 Mn and 59 Co in Ni are in agreement with the band structure for these impurities. For 101 Ru in Ni, our results show the occurrence of a large density of impurity d states at the Fermi level corresponding to an extended virtual bound state.
