In this study, an optimized method was presented for the reverse quartz flotation in iron ore purification where sodium oleate (NaOL) always selected as collector due to its accessibility and economic benefits. Three alcohol ethoxylates, octylphenol ethoxylate (OP-10), nonylphenol (NP-10) fatty ethoxylates (AEO-9) were introduced improve collecting performance of NaOL quartz. It turned out that...

It is more common than not, for mineral processing studies to proceed via the examination of model flotation systems with the resulting data often lacking statistical verification. The resultant concentrates and tails may then be subjected to a restricted range of analyses, for diagnosis of the flotation behavior variations observed, that themselves bias the outcomes. For instance surface analy...

A study was carried out to determine the effect of water quality on flotation performance. The experimental test work comprised of batch flotation tests using Denver lab cell for a period of 10 minutes. Nine different test runs were carried out in triplicates to ensure reproducibility using different water types from different thickener overflows, return and sewage effluent water (process water...

Density flotation has been frequently used for the extraction of nematodes from field samples. Density flotation curves for four nematode species and five solutes have been prepared. The curves confirm that flotation was governed by several factors: solute density, solute osmotic activity, and physiological properties of the nematode species. Nematode viability and function can be adversely aff...

In the flotation process, the concentrate grade and the tailing grade are crucial technical indices which reflect the product quality and efficiency. There are strong nonlinearity and uncertainty in such technical indices dynamic behaviors, which can hardly be described using accurate mathematical model. The technical indices which cannot be measured online continuously vary with boundary condi...

Froth flotation is a popular process used for the extraction of certain minerals from ore. The effective automatic control of this process has great financial importance. Utilising machine vision as the measurement component of an automatic flotation control system has several advantages: it is a cost effective solution due to its non-contacting sensors and consequent low maintenance, as well a...

In this study, we investigated for the first time whether flotation-REST might be used for treating chronic whiplash-associated disorders (WAD). Six women and one man, all diagnosed by licensed physicians as having chronic whiplash-associated disorder, participated. Two of the participants were beginners with regard to flotation-REST (2 or 3 treatments), and five of them had experienced between...

The flotation version of restricted environmental stimulation technique (REST) has been shown to improve perceptual-motor skills in sports and creativity in the sciences. We examined whether these effects would extend to jazz improvisation—an activity involving perceptual-motor coordination and creativity. College students enrolled in an intermediate-level jazz improvisation class (N 1⁄4 8) flo...
