Copper isotope evidence for large-scale sulphide fractionation during Earth’s differentiation [PDF]

, 2015
The differentiation of Earth into a metallic core and silicate mantle left its signature on the chemical and isotopic composition of the bulk silicate Earth (BSE).

Simultaneous fractionation of sulfur dioxide explains mass independent fractionation of sulfur isotopes in Archean sedimentary pyrites

, 2021
The relationship between ∆36S and ∆33S in Archean sedimentary pyrites has been used to evaluate early geologic processes, including photochemical reactions in the anoxic atmosphere, biological activity and thermochemical alteration during sediment ...

Characterising Coarse Particle Gangue Densimetric Separation Response in Gold Bearing Sulfide Ore Broken by Different Fine Crushing Modes [PDF]

, 2020
The separation behaviour of gangue during densimetric classification and the subsequent inherent propensity to pre-concentrate metal values in gold-bearing sulfide ore is reviewed in this thesis.

Estimate of Sediment Pickup Rate with the Densimetric Froude Number

, 2015
The present study shows that the sediment pickup rate is better correlated with the densimetric Froude number than the Shields number. With laboratory data collected in open channel flows, an empirical formula for estimating the pickup rate is proposed ...

A novel binary particle fractionation technique

, 2010
An interesting development towards a robust particle fractionator is presented. Typically acoustic fractionators rely on time of flight in a constant acoustic field to separate different populations .
