Historically most sulfide nickel ore bodies have had grades of 1% to 2% Ni, mined underground at relatively low production rates and with high operating costs. Laterite nickel deposits can be bulk mined, but the nickel can't be concentrated, so that both capital and

Nickel laterite ore had a complex internal structure and mainly consisted of limonite (10 wt.%) and serpentine (87 wt.%). Sulphides were not a significant part of this laterite ore and were rarely observed. Furthermore, the nickel was mainly hosted in serpentine by substitution for Mg or by adsorption.

Monel (alloys of nickel and copper), is a hard compound and can resist corrosion by seawater. Hence, it is used in propeller shaft in boats and desalination plants. Properties Of Nickel. Nickel is silvery-white, hard, malleable, and ductile metal. It is a good conductor of heat and electricity. It is bivalent, that is it has a valency of two.

The corrosion of low-grade nickel sulfide ore shows characteristic kinetic current. A. ferrooxidans facilitates the electron exchange by reducing resistance, improving diffusion of product layer, and accelerating transformations of the Fe 3+ /Fe 2+ couple and S 0 /S 2− couple for promoting sulfide mineral corrosion. As a result, the average ...
