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 0.352 nm, giving an atomic radiusof 0.124 nm. This crystal structure is stable to pressures of at l

Pre-concentration of nickel in laterite ores using

Sep 01, 2019Of course, upgrading nickel using magnetic separation highly depends on the ore mineralogy and mineral liberation, and if nickel is associated with magnetic minerals. Table 3 also shows that the percentage of iron increases (by ~70%) in the magnetic product for ores S and I, but not for ore L. On the other hand, more silicon bearing minerals
