Sentence examples for mineral surface is from inspiring English sources

In the EDL model, a negatively (or positively) charged mineral surface is surrounded by a layer of electrostatically attracted cations (or anions) as the counter ions.

The reactivity of a mineral surface is determined by the variety and population of different types of surface sites (e.g., step, kink, adatom, and defect sites).

In this work pore-scale modeling of coupled fluid flow, reactive transport, and heterogeneous reactions at the mineral surface is applied to account for permeability alterations caused by precipitation-induced pore-blocking.

Our results showed that work function on olivine mineral surface is mainly affected by surface morphology and crystal orientation and that the variation range of work function is 7.3 8.5 eV.

In all these scenarios, the reactivity of HS (towards complexation with Fe(II), Al III), and/or the mineral surface) is the cause of interference with Fe(II) precipitation, which implies that effects will vary with the chemical properties of HS.

For example, the sulfur oxidizer Thiobacillus caldus is very efficient at removing the elemental sulfur layer that forms on arsenopyrite and other sulfide minerals during oxidative dissolution.[14] The abundance of elemental sulfur at the mineral surface is certainly a determining factor in the growth of such microbial communities.

For comparison, the fractured mineral surface was also studied by XPS.

Charges on the mineral surface were also linked to observed wettability change.

Based on these analyses, an adsorption model of the mixed collector NaOL/DTAC on the mineral surface was drawn.

The various reactions occurring on the mineral surface were investigated by a range of techniques, including OH− addition to maintain the grinding pH, ethlenediamine tetra acetic acid disodium salt (EDTA) extraction, X-ray photoelectron spectroscopy (XPS) and Time-of-flight secondary ion mass spectrometry (TOF-SIMS) measurements.

The static adsorption onto the mineral surfaces is measured by the depletion method.
