Apr 01, 1983· The flotation method most commonly applied is the one that is based on cationic flotation of silica and silicates (reverse flotation), and which is preceded, or not, by desliming or selective flocculation. INTRODUCTION Research on the flotation of iron ore, on either a bench or a pilotplant scale, started towards 1931 (Crabtree and Vincent, 1962).

Froth flotation of silica from iron ore Free Patents Online Under the conditions of the flotation trials, 105 pounds of lime per ton of 70 feed as used in test 4 was sufficient to yield a substantially saturated pulp, and gave good flotation of the silica and retardation of the iron oxid ...
A bulk of silica sand was taken from KowliKosh silica sand mine to reduce its hematite content by reverse flotation. The raw sample consisted of % SiO 2 and % Fe 2 O 3 and traces of Al 2 O 3, CaO, MgO, Na 2 O, K 2 O, TiO 2.
This invention relates to the use of a primarybranched aliphatic ether monoamine, 3nonyloxypropylmonoamine, its ethoxylated or propoxylated derivatives and partial acid salts thereof, as a major or minor constituent in the formulation of superior silica flotation collectors. Such collectors are employed in the separation of silica from iron ore, phosphate, and other valuable ores.

The ore is suitably prepared so that the bulk of the silica gangue may be floated away from the iron using a relatively cheap anionic reagent. lTailings from this flotation contain the bulk of the...
Flotation response of iron ore depends on its impurities. • Silica rich ores float better compared to alumina rich ores. • Clay and gibbsite coat on hematite and hinder flotation. • SEM studies support less coating of quartz due to coarser size. • Silica in the form of jasper present in BHJ ore is less floatable.

The nickel content from low grade nickel lateritic iron ore is upgraded by a combined process of segregation and magnetic separation or flotation. Ground ore is thoroughly mixed with a small quantity of calcium carbonate, calcium sulfate and coke and is sprayed with a solution of sodium chloride to make appropriate pellets. These pellets are gradually heated under a neutral or a slightly ...
Mar 01, 2009· The chemical analysis presented in Table 1 shows a very high content of SiO 2 in the sample (%). Quartz content is represented as insoluble silica (In SiO 2), and SiO 2 in kaolinite is the reactive silica (Re SiO 2).Available Alumina (AA) shows the alumina content in gibbsite, recoverable by the Bayer process: % in the head sample.

May 30, 2016· A series of flotation tests on Chador Malu samples were carried out to evaluate the effect of different silicate–metal salts mixtures on the apatite–iron oxides–silica flotation system. Experiments were performed at 800 g/t sodium silicate with modulus of and at the pulp pH of 10, using different silicate–metal mixtures.
The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
