Jun 28, 1990 BACKGROUND OF THE INVENTION. This invention is related to reverse flotation processes wherein silica or siliceous gangue is floated. Flotation is a process of treating a mixture of finely divided mineral solids, e.g., a pulverulent ore, suspended in a liquid whereby a portion of the solids is separated from other finely divided mineral solids, e.g., silica, siliceous gangue, clays and other ...
By this work, selective flotation of various chromite ores were studied to determine some of the features of flotation. Different chromite ores from South Africa were made flotation using the anionic collector, A825 petroleum sulfonate, after conditioning with H2SO4 at low pH values in the range of 1 and 3.

In these flotation tests, chromite minerals were floated and separated from gangue minerals in presence of H 2 SO 4 very effectively. The results in the Table 2 show that higher recovery ratio of chromite with lower recovery ratio of silica has been obtained at low pH values for almost all chromite ores. Flotation 1 st Cleaning 2 nd Cleaning 3 ...

Chromite ore with a small amount of coke is ground wet in a ball mill after which chromite are minimied by i rejecting chromite to tailings during flotation in socalled chromite glae the result of chromite being fluxed by silica or clay Fayalite is not magnetic and so cannot be separated from the sand magnetically.
Batley 1972. Olivine is an orthosilicate containing isolated silica tedrahedrons and divalent magnesium and ferrous ions in changeable proportion Batley 1972. The response of chromite to fatty acid flotation in a wide pH range has been discussed according to the
Claim cation Date 27.06.91 F AMERICA 1. A froth flotation process for the separation of silica or siliceous ganguie from mineral values wherein the silica or siliceous gangue and mineral values In particulate form in an aqueous slurry are subjected to froth flotation in the presence of an amine collector and an alkanol amine corresponding to the formula NH3x wherein x is from 1 to 3 and R is ...
Preconditioning with fuel oil permitted flotation of the chromite from the flocculated siliceous-gangue slimes. Recoveries of up to 91 percent were realized with products containing up to 45 percent Cr 2O3 Hunter and Sullivan, 1960. The CrFe ratios ranged from 2.17 to 2.46. Oleic acid was used for flotation.
Jun 05, 2017 The technique was also applied to chromite gravity concentrates to further upgrade chromite and to reject silicates. Flotation of a gravity concentrate containing 40.9 percent Cr2O3 and 4.4 percent SiO2 recovered 90 percent of the chromite in cleaner products containing 44.9 percent Cr2O3, and 0.63 percent SiO2.

Nov 23, 2020 Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditions.
face behavior of chromite for effective flotation. The source minerals of manganese include pyrolusite, psilomelane, wad, manganite, rhodonite and rhodochrosite. These minerals are frequently associated with silica and aluminum silicates. FLOTATION BEHAVIOR Chromite
process and found that significant removal of iron bearing mineral such as goethite and silica is possible using FDS in a single stage operation. The maximum of 83 recovery of chromite is possible with 22 to 23 Cr2O3 content and thus obtained FDS underflow is suitable for flotation circuit.
