From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture. A rotary dryer is then used to reduce the moisture content to 1 percent or less. Rotary dryers are the most common dryer type used, although fluid bed dryers are also used.
Silica and siliceous gangue are separated from desired mineral values, particularly iron and phosphate, by reverse froth flotation in the presence of amine collectors and effective amounts of alkanol amines such as diethanol amine.
The flotation circuit (FIG. 11) can then be separated into low silica and high silica flotation set ups giving much more flexibility to this process with some alternative interchangeable streams between both circuits. The low silica flotation feed in this embodiment receives the UF (−74 microns to 6 microns) from the desliming circuit stage.
flotation experiments were conducted at different energy dissipation rates, gas rates, froth heights. The flotation tests were also carried out on mixtures of hydrophobic silica and hydrophilic magnetite particles, so that the grades of the flotation products can be readily determined by magnetic separation.
AMINE COLLECTORS FOR SILICA (SANDS) The chemical processing plants are becoming more and more tolerant to Insol content in the acidulation feeds. As a result, the Insol levels in flotation concentrates have been relaxed from 5% to 3 58%.

Depression of the flotation of silica or siliceous gangue in mineral Patent... A flotation process is disclosed wherein the selectivity to the valuable mineral is improved by the depression of silica or siliceous gangue by the use of a hydroxycontaining compound such as an alkanol amine.
Successful application of the polymeric collector for fine silica flotation: Lupromin FP18 AS Mining Solutions
Water, surface and reagent chemistry experiments were performed at a laboratory, pilot, and full plant scale during the course of this work. Many of the conclusions developed in. the laboratory and pilot scale were found to be true at the full plant scale as well.

Application of carbonatesilica flotation techniques to western phosphate materials. [Avondale, Md.] : Dept. of the Interior, Bureau of Mines, 1982 (OCoLC)
The Jameson Cell can be used for the reverse flotation of silica from iron ore, where flotation columns have traditionally been used. Phosphate flotation. Phosphate processing operations that use flotation as the principal mechanism to concentrate the phosphatebearing minerals usually discard particles smaller than 20 µm in diameter.
Abstract. The recovery of iron from the screw classifier overflow slimes by direct flotation was studied. The relative effectiveness of sodium silicates with different silicatosoda mole ratios as depressants for silica and silicate bearing minerals was investigated. Silicatosoda mole ratio and silicate dosage were found to have significant effect...

A process for the recovery of mineral values by froth flotation comprising subjecting a particulate ore, which contains silica or siliceous gangue and is in an aqueous slurry, to froth flotation under conditions such that the minerals to be recovered are floated and the flotation of the silica or siliceous gangue is depressed, wherein the flotation is carried out in the presence of an anionic collector and a hydroxy .
found that the flotation behavior of kaolinite is opposite to that of silica. For example, ether diamine, a st rong collector for silica, does not induce any flotation of kaolinite at pH 10. The pH dependence of kaolinite flotation is also opposite to that of silica, which explains why it is difficult to remove kaolinite in iron ore flotation[29].
