flotation separation of barite from iron ores

Flotation Reagents Collectors Froth flotation is the most widely used industrial process for the separation of finely liberated minerals The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to Selective flotation of fluorite from barite using Micro-flotation results showed that good floatability of both fluorite and barite was obtained at around pH 8 5 using sodium oleate (NaOL) as a collector TSP showed a selective depression for barite and flotation separation of fluorite from barite was achieved using TSP as a depressant and

Separation Behaviour of Iron Ore Fines in Kelsey

Kelsey Centrifugal Jig was found to be promising for the beneficiation of fine iron particles The present study was car-ried out to have a better understanding of the separation process of Kelsey Jig through detailed experimentation Ben-eficiation of fine iron ore fines was studied in Kelsey Jig

separate minerals and froth flotation are two of the most common methods used to beneficiate barite [9 10] Using froth flotation barite samples with concentration of over 95% BaSO 4 have been obtained from different sources tailings [4] from complex iron ore in Bulgaria [5] 96 32% and 91 26% respectively from low grade

Here is a brief introduction of iron ore reverse flotation method Flotation technology is widely used in iron ore separation Conventional flotation method was adopted to remove the impurity of iron concentrates but it turned out to be a poor performance In order to solve this problem reverse flotation method is found to be efficient in


BENEFICIATION OF AZARA BARITE ORE USING A

separate minerals and froth flotation are two of the most common methods used to beneficiate barite [9 10] Using froth flotation barite samples with concentration of over 95% BaSO 4 have been obtained from different sources tailings [4] from complex iron ore in Bulgaria [5] 96 32% and 91 26% respectively from low grade

Flotation circuits are often operated at a pH range of 7 5 to 11 5 The exact range at any given plant is optimized for the ore at that site Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite Particle Size The particle size to which the ore is ground depends on the nature of the ore

3 This iron ore slurry is pumped to the agitation tank This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~-0 074 mm) going to froth flotation cells for recovery of iron 4 In magnetite processing plant the process of flotation separation is replaced by magnetic separation

As reported SPS has been extensively applied in the flotation of silicate and iron ores but seldom have researchers examined the performance of SPS in the flotation of fluorite or barite Apart from collectors depressants are vital to achieve desirable separation results in fluorite ore beneficiation

In flotation of fluorite it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral and ensures the quality of fluorite concentrate Mixed flotation of fluorite and barite flotation and then separate them In mixed flotation obtain

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing paper recycling and waste-water treatment industries Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century

barite ore separation for sale Barite 2013 USGS Mineral Resources Programwashing or more complex methods such as flotation heavy media separation or magnetic separation Most barite ores require some upgrading to minimum commercial purity or density levels the primary use of barite is as a weighting agent in drilling muds

A combination of classification (initially screens to remove the coarser 'impurities' then hydrocyclones to remove the finer 'impurities' with some barite loss) gravity (calcite/fluorspar/silica from barite and sulphides from barite) and flotation (oleic acid/alkyl sulphonates/sulphates with sodium silicate as the dispersant and neutral to alkaline pH - barite is depressed at acidic pHs)
