Flotation of the corundum using petroleum sulfonate in an acid circuit resulted in a concentrate containing 89.7-pct corun dum with a recovery of 75.5 pct. Flota tion of the carbonate minerals using sodium oleate in an alkaline circuit prior to flotation of the corundum resulted in a higher grade concentrate
Bureau of Mines conducted laboratory-scale beneficiation tests on a sample of corundum gneiss from Montana to devise a method for beneficiating corundum for use as a substitute for refractory-grade bauxite. A flotation process utilizing petroleum sulfonate as the collector in an acid circuit was devised.

In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, [21] requiring little or no addition of collector).
A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate

Mineral processing Mineral processing Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic

Results showed that two flotation schemes each produced a concentrate exceeding the national stockpile specifications for calcined bauxite. From a feed containing 28 pct corundum, concentrates containing up to 92.5 pct alumina (al2o3) were produced with a corundum recovery of 78.5 pct.

Flotation recovery of corundum (Al 2 O 3) with 4x10-5M additions of collector Quartz has a pzc of 1.8. Anionic collectors such as sulphonates or alkyl sulphates are not adsorbed in sufficient amount below the pzc to promote flotation.

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.
The concentrate tested was a flotation concentrate from the Northmet project, USA, assaying 14.7% Cu, 3.05% Ni, 0.14% Co, 26.7% S, 1.4 g/t Au, 2.2 g/t Pt, and 9.9 g/t Pd. Pressure-oxidation conditions were 225 °C, pulp density was 11%, retention time was 120 min, and oxygen overpressure was 689 kPa. The ore treated had a P80 of 15 μm.

Thickening tests on flotation tailings and final flotation concentrates Filtration tests on the final flotation concentrate. It should be noted that flotation retention times determined by laboratory testing are generally scaled-up by a factor (depending on the mineral in question) to establish the retention requirements needed in a commercial concentrator.
1 Froth Flotation Fundamental Principles concentrate, and tailings, respectively; and f, c, and t are the assays of the feed, concentrate, and tailings. We now need to eliminate T from these equations so that we can solve for F/C: Ff = Cc + Tt, and multiplying (F = C + T) by t gives us:
