3-8-2020 · From laterite ores. Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.
Lateritic nickel ore deposits - Wikipedia
Genesis and types of nickel laterites. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization.

Nickel | Geoscience Australia
After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and stone processing methods.
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 ...

What Is Nickel Smelting? (with picture)
22-6-2020 · Alex Newth Last Modified Date: June 22, 2020 . Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground.
Nickel Ores - ChestofBooks.com
The principal ores of nickel are magnetic nickeliferous pyrites, nickel arsenides (especially kupfer nickel, and nickel arseno-sulphide or grey nickel), and the hydrosilicates of nickel and magnesia.. The first-named ore is simply magnetic pyrites containing a certain proportion of nickel sulphide, and is one of the most important.
