Barwise, C. H. : Barite flotation with Flotbel selective collectors, note technique-Fospur Ltd, Somercotes, Derby, England, March 1988. Selective flotation of non selective minerals Jan 1957
Barite (barium sulphate) often occurs as large veins or beds, as gangue mineral in various mineral veins, in limestones, sandstones and like deposits.The ores are generally low grade and require concentration by flotation to meet market specifications. Barite, which has the ability to influence other materials with its basic characteristics, makes this heavy spar indispensable in maintaining ...
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).

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
The above results suggest that flotation separation of barite from calcite can be realized when the AWG is used as a depressant for calcite. Hence, flotation tests of barite and calcite mixture with the mass ratio of 4:1 were performed in the present and absence of AWG using NaOl as the collector at pH ˜8, the result of which is shown in Table 2 .

of flotation were applied to barite and fluorite-barite ores. Definitive choice of optimal flotation requirements focused on Petronate L (1000 g/t ; pH 6.5) for barite flotation and on Flotbel R171A (100 g/t ; pH 9) for fluorite, combined with potassium dichromate as depressing agent for quartz and barite.

Barite flotation tests carried out in the pH range comprised between 3 and 10 have given a maxi-mum flotation rate at natural pH (6.2), with a con-sumption of 500 g/t. This recovery decreases up to 33% and up to 62%, respectively at pH 3 and pH 10, which gives a bell-shape curve. Increasing of
The barite rougher flotation is rapid and the addition of a small amount of reagent towards the end of the circuit assures ample froth for the scavenger operation. The rougher concentrate is cleaned three times, using plenty of clean spray water to cleanse the froth and obtain satisfactory slime rejection.

Over-grinding of the brittle minerals is avoided by stage grinding and careful selection of equipment. We have experience in diverse regimes for treatment of a wide range of oxide minerals such as • barite
The flotation results showed that SPS performed well in a wide pH region (7–11) even at a low temperature (5 °C), while the flotability of fluorite and barite were almost the same.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

concentrator was converted from mechanical flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs. The ore is a volcanic phosphate ore containing approximately 20 %P 2 O 5 (27% to 28% CaO) primarily as apatite. Principal impurities are barite (9% to 15% BaSO 4), hematite (19% to ...
The flotation flow sheet was modified to reject barren coarse and/or slime fractions from some of the samples, and one feed sample had to be scrubbed prior to flotation to remove residual flotation reagents. The cleaned concentrates had BaSO4 contents ranging from 95.0 to 96.9 percent, while recovering 81.2 to 95.9 percent of the barite in the ...
