The recovery and concentrate grade, used simultaneously, are the most widely accepted measures of assessing metallurgical performance. Meanwhile, new challenges are being found with more complex ores around the world, a new methodology to evaluate flotation circuits more accurately is used to keep the Mineral Industry afloat in a changing world by increasing revenues. The flotation process is d...

Flotation is the single most important method of mineral processing and is widely used for the concentration of metal ores, industrial minerals, and coals. Several investigations were carried out during the last century, and the flotation literature was immense, particularly on selective collectors and their interaction mechanisms on sulfide, oxide, and silicate minerals. However, it is often d...

in this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. the effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. a software based experimental design approach (dx7) was applied to determine and mod...

In the oil industry, strontium sulfate (SrSO4) scale deposits have long plagued oilfield and gas production operations. This remains an unsolved problem. We here show how bubble column evaporator (BCE) can be used to control aqueous precipitation from salt solutions. Mixtures of nitrate sodium in BCE system were precipitate at different degrees supersaturation. The effectiveness was compared st...

Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

Plasma high-densitjj lipoprotein (HDL) consists of a number of structurally and functionally distinet subspecies. Flotation procedures permit the separation of HDL, and HDL, (density ranges 1.063-1.125 and 1.125-1.21 g/ml, respectively), whilst apolipoprotein (apo) E-rich and apo E-poor subfractions have been obtained by heparin-Sepharose affinity chromatography (Weisgraber & Mahley, 1980). Alt...

Flotation constitutes a gravity separation process, which originated from the minerals processing field. However, it has, nowadays, found several other applications, as for example in the wastewater treatment field. Concerning the necessary bubble generation method, typically dispersed-air or dissolved-air flotation was mainly used. Various types of biological materials were tested and floated ...
