·In this paper −10 μm rutile and −30 μm garnet particles were selected as samples The effects of different reagents on the flotation of rutile and garnet single minerals were studied and
·Effect of different particle size fractions on flotation separation of fine rutile from Advanced Powder Technology IF Pub Date 2024 03 11 DOI / Shiman Zhu Liuyi Ren Shenxu Bao Yimin Zhang Bo Chen
·Chen et al [22] utilized garnet to control the rheology of flotation pulp in fine scheelite flotation and found that the pulp viscosity decreases and the flotation rate increases when garnet was
·Separation of calcium bearing minerals from themselves is very difficult because of their same surface properties Pugh and Stenius 1985 Marinakis and Shergold 1985a This is due to the presence of the same cation Ca 2 at the surface and very similar anions WO 4 2− CO 3 2 and PO 4 3− Marinakis and Shergold 1985b Filippova et al 2014 The low
·Improvement of flotation performance through de sliming pretreatment Omphacite and garnet fines are easily entrained into the froth and result in a low grade product De sliming was found to be indispensable before flotation to mitigate the detrimental effect of fine gangue mineral particles and improve the flotation performance [30] [31
·The problem of flotation separation still remains without the addition of extra reagents Deng et al 2016 After rough concentration of tungsten minerals the conventional Petrov process is applied for further separation of scheelite from other calcium minerals which requires steaming of bulk concentrate in 2 4% solutions of sodium silicate Na2SiO3 at
·The physical and chemical properties of feldspar and quartz are highly similar thus they cannot be easily separated effectively In this work the flotation separation of feldspar from quartz using sodium fluosilicate Na2SiF6; SF as a selective depressant was investigated Moreover the influence mechanism of SF on the selective flotation separation of feldspar and
·One of the most widely used ore beneficiation methods is froth flotation which allows for effective processing of complex metallic ores and coal The primary goal during coal processing involves reducing the ash and sulfur content whereas during metallic ore processing it includes the separation of metals like copper lead and zinc from the
·Abstract Chemical zoning of garnet is often used to deduce P T paths of rocks by inverse calculation To validate the derived P T paths it is desired to establish a method to predict the chemical compositions of garnet theoretically This study proposes a new forward calculation of the formation of Mg Fe Mn garnet from chlorite which solves the non linear
·Flotation is an effective sorting method for difficult ores in ilmenite beneficiation and can upgrade the ilmenite quality to commercial levels [5] [6] [7] of fine minerals including rutile has long been a challenging research focus This study selected rutile and garnet samples with size fractions of −15 −38 and −74 μm to
·It is well known that particle size plays a critical role for the froth flotation especially for flotation separation between two or more minerals [4 5] Grinding is necessary to achieve one mineral liberates from other minerals as a result fine grinding of coarse grained minerals is of interest to the mineral processing plant for its higher energy consumption and
·Demir 2010 proved that cationic flotation as amine using HF and NaCl as adjustor and depressant respectively is an effective method of separating Na from K feldspars from a weathered granite Fluorides produce sites of charged aluminum/fluoride complex at the mineral surfaces onto which cationic collectors adsorb Buckenham and Rogers
·The suppressing effect by fine hydrophilic mineral particles suggests that effective dispersing methods are required in order to reduce the masking interaction and realize more effective flotation in the future The interfacial interaction energy determining the aggregating behavior agreed well with the experimental results and can thus be a
·Quantitative P T path determination in metamorphic rocks is commonly based on the variation in composition of growth zoned garnet However some component of growth zoning in garnet is necessarily the result of an effective bulk composition change within the rock that has been generated by crystal fractionation of components into the core of garnet
·The selective separation of scheelite from fluorite is difficult because of their similar surface properties In this study diethylenetriaminepentaacetic acid DTPA was used as a novel depressant for the efficient removal of fluorite from scheelite and its depression effect and mechanism were systematically investigated by conducting micro flotation experiments and a

·A novel chemical scheme for the flotation of rutile from eclogite tailings has been developed in this work It consists of lead ion as the activator sodium fluorosilicate SF as the depressant and styryl phosphonic acid SPA and n octyl alcohol OCT as the using the proposed scheme to treat a feed ore of % TiO 2 a rougher concentrate of grade
·The recovery of scheelite from calcium bearing carbonate ores by foam flotation is challenging due to its low separation efficiency This study investigated the effect of pentasodium diethylenetriaminepentaacetate PD on the surface properties of scheelite and fluorite For this purpose we performed micro flotation tests and carried out zeta potential
·Additionally several characterization methods were used to evaluate the improvement of leaching performance The addition of oxidants and fluorinating aids strengthens the acid leaching process which greatly destroys the structure of a garnet which is conducive to the extraction of vanadium in a flotation concentrate
·The efficacy of flotation separation is dependent on the effective liberation of the valuable minerals for reagent attachment Over the last two decades major PGE producers embarked on optimisation campaigns to improve recovery whilst reducing % Cr 2 O 3 to < % in the final flotation concentrate for the UG2 ore feed Nel et al 2004 Vos
·Since the density difference between rutile mineral and omphacite is large but the difference between rutile and garnet is small a shaking table can separate rutile and omphacite well though rutile garnet separation is challenging 5 Flotation separation Foam flotation can separate fine grained rutile and remove undesired deposits like
·The shaking table can separate quartz tourmaline garnet and part of white titanite as tailings And the rutile is enriched in the shaking table s medium ore and concentrate 2 Magnetic Separation Flotation Flotation is an effective method for separating fine grained rutile and reducing metal loss 5 Pickling
·Flotation is a physicochemical process that is used for the separation of hydrophobic particles from hydrophilic ones This method is widely used in mineral processing for the selective separation of valuable minerals On the other hand positive bias conditions are more effective in a cleaner stage and fine particle flotation Table 1
