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...

Traditional processing of kaolin is achieved by dispersion of the mined ore and classification by means of multistage hydrocyclones. The inefficiencies inherent to cyclones produce a middling product that is commonly disposed back to the quarry. In this research recovery of kaolinite from tailings of the Zonoupz kaolin washing plant, which is located in Iran, was investigated by cationic flotat...

Flotation wastes are becoming a valuable secondary raw material and source of many metals semimetals worldwide with the possibilities industrial recycling. The flotation tailings contain oxide sulfide minerals that have not been sufficiently stabilized form acidic mine waters, which in turn contaminate groundwater, rivers, reservoi6sediments. An effective way to recycle these is recover through...

Usually, the concentration of minerals is carried out with a set flotation and grinding units. Most modeling strategies for stages have followed separate developmental paths. This paper presents strategy based on using studies to model via an integrated approach. The methodology, which approximate method that allows one study effects circuits, applied copper sulfide mineral appropriate results....
