This effect can be used to separate, concentrate, manipulate, trap, target and transfer macromolecules such as bio-molecules and DNA in a microchannel.
All ore coming out of the mines is low-grade, with iron content of around 35%. Pelletizing that ore a laborious process of grinding, separating, concentrating, filtering, drying and heating bumps that content up to 65% or so.
Flotation makes possible the processing of complex intergrown ores containing copper, lead, zinc, and pyrite into separate concentrates and tailings an impossible task with gravity, magnetic, or electric separation methods.
To obtain separate concentrates by selective flotation involves high unit-cost, poor quality of the concentrates and relatively low overall recoveries [ 15].
Governmental power was to be separated, not concentrated.
The assay bead is dissolved in aqua regia and the metals separated and concentrated, often by solvent extraction.
A few hundredths of a percent of such metals as nickel and cobalt and a percent or so of manganese also are generally present in a micronodular fraction of the clays and in all likelihood can be separated and concentrated from the other materials by a screening process or by some other physical method.
Distillation: The brew from the fermentation process is separated and concentrated into 95percentt pure alcohol, water, and other residues.
The organic phase was separated and concentrated before injection of the totality of the sample in gas chromatography (GC, Thermo Finnigan Trace GC; HP-5 Agilent column).
Secreted fungal proteins were separated and concentrated from supernatants of 24-h hyphal cultures by extensive ultrafiltration/dialysis through a low-adsorbance ultrafiltration membrane (molecular cut-off 10 kDa, Millipore, Bedford, MA), as described elsewhere [92].
