The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field.

The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua ...

nickel processing, preparation of the metal for use in various products.. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a face-centred cubic crystal structure, which gives ...

The invention relates to a method for directly reducing laterite nickel oxide ore to enrich nickel by an ore smelting electric arc furnace. The method comprises the following steps of: crushing the laterite nickel oxide ore until the granularity is 100 to 320 meshes, drying, adding a carbon reducing agent which is 3 to 13 weight percent of the laterite nickel oxide ore, reducing by adopting ...
