Nickel Flash Smelting Total Materia Article

Nickel Flash Smelting Total Materia Article

Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte. Nickel (Ni) is a silvery-white, hard metal.

NICKEL AND COBALT ORES FLOTATION

The nickel content in such sulRde ores is generally low (0.23%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde

Smelting Reduction of Spent Catalyst Containing Nickel A

The aim of this research was to study the recycling process and the feasibility to smelt the spent nickel catalyst for the production of nickel alloy or ferronickel. The smelting process was carried out in a laboratory induction furnace. The effects of SiO2/CaO for slag forming on metal recovery and smelting time were investigated. Petroleum coke was used as reductant.

What Is Nickel Smelting with picture Info Bloom

Nickel requires higher smelting temperatures (in the range of 1,350 C 2,460 F) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
