Nickel Sulphide Flotation From Serpentine

Teck's CESL Nickel Process: Advancing Towards a …

3 Nickel Sulphide Resources1 Nickel resources are typically classified as sulphides or laterites. Approximately 73% of the world’s nickel resources are estimated to be contained in laterites while 27% are as classified as sulphide. Currently, some 37% of the world’s nickel supply is derived from sulphide resources and almost all

contaminate metallic mineral concentrates during traditional flotation of coarse sulphide particles. This could pose quite a complicated and challenging problem in the case of some types of low-grade and finely disseminated Cu-Ni ores bearing high serpentine contents. This is the case for the copper and nickel sulphides from the Yunnan Mine, China.

Upgrading nickel in laterite ores by flotation - ScienceDirect

Jun 01, 2018· This size fraction corresponds to a P 80 of about 140 µm which is appropriate for flotation tests. The nickel head grade of samples L, I and S (at the −300 µm size fraction) was found to be 1.2%, 1.1%, and 3.0%, respectively. Nickel was found, more or less, at the same grade in all size fractions in these laterite ore samples.

Leaching of Low Grade Nickel Sulphide Serpentinite Ores: A ...

A low-grade disseminated nickel sulphide serpentinite ore from W.A. had a relatively high permeability after drying. Various techniques indicated that the permeability resided within a fine network of fibrous vein- lets and especially within coarse cracks along which the sulphides lay. The ore minerals were therefore open to selective extraction by chemical leaching.
