flotation and dewatering of nickel

• 

  Dr Xumeng Chen - UQ Researchers

  The selection, testing, and commercial utilization of flotation reagents is best carried out in stages through microflotation tests on pure minerals and their synthetic mixtures followed by bench-scale batch flotation tests on the ore. A systematic approach to quantitatively evaluate different reagents, in particular, through the analysis of batch flotation data, has been …

  Investigation into the mineralogy and flotation performance of …

  20141015 · The objective of this study was to investigate the effect of geological oxidation/alteration on the mineralogy and flotation performance of PPM “silicate reef” ore. Oxidised PPM ore is characterised by high contents of alteration minerals (talc, serpentine, chlorite), Fe-oxides/hydroxides and negligible BMS.

  Effects of particle size on flotation parameters in the separation …

  2017715 · The classical first order flotation kinetics were used to fit the flotation data and first-order rate constant (k ), ultimate recovery ( R∞ ), modified rate constant ( Km ), selectivity index ( SI) and separation efficiency ( SE) were calculated and used as the flotation parameters to evaluate the separation effect of the two minerals.

  2021101 · Abstract The mining of ultramafic ores is required to meet society’s continued demand for nickel. These deposits, however, are difficult to process due to their high serpentine content. Serpentine, a gangue mineral, increases slurry viscosity, slime-coats the valuable Ni-bearing mineral pentlandite, and reports to and dilutes the froth …

  2022223 · The most commonly used dewatering methods include dewatering stockpiles, dewatering screens, thickeners, and filters (vacuum belt and pressure type). One of the most widely used ore beneficiation methods is froth flotation which allows for effective processing of complex metallic ores and coal.
