reagents in zinc recovery from pb- flotation tailings of
effect of concentration parameters on recovery of zinc oxidized minerals from lead flotation tailings of dandy mineral processing plant in north-western iran was studied. a sulfidization-flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent, primary amine as collector, dispersants and flocculants with diffe...
متن کاملEffect of Flotation Procedure and Composition of Reagents on Yield of a Difficult-to-float Coal
The paper discusses two procedures of flotation of difficult-to-float oxidized coal. The first one is the normal flotation procedure which relies on wetting coal with water followed by addition of flotation reagents (dodecane, dodecyl tetraoxyethelene ether (C12E4), and 1-pentanol). The second, direct contact procedure consists of mixing pure reagents with dry coal followed by addition of water...
متن کاملA computer simulation study of sorption of model flotation reagents to planar and stepped {111} surfaces of calcium fluoride
Atomistic computer simulation techniques were employed to investigate the interaction of a selection of organic surfactant molecules with different surface features of the calcium fluoride {111} surface. The adsorbates coordinate mainly to the surface through interaction between their oxygen (or nitrogen) atoms to surface calcium ions, followed by hydrogen-bonded interactions to surface fluorid...
متن کاملFlotation of Biological Materials
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 ...
متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
