Graphite can be easily enriched by flotation because of its high natural hydrophobicity . isobutyl carbinol are used as frothers and sodium silicate, quebracho and starch are
Quartz, clay and other silicate Reverse adsorptjo!!of s~rfactants Hydrophobicity flotation of quartz using a cationic surfactant. The depression might party be due to the competitive interaction between the polymer and amine at the adsorption sites on the mineral PAMD is known to adsorb well on quartz and even cause flocculation
Reverse cationic flotation is the most-common approach for hematite-quartz separation Amines are used as collecting reagent; two amine variants supplied by . reverse flotation in mining
When complete silica removal is required, various combinations of Reverse Osmosis and ion exchange processes are used. RO systems are currently unable to remove as much silica as ion exchange can but is far better at removing various forms of non-reactive silica and will remove many additional contaminants not addressed by ion exchange.
Flotation systems for removing silica from magnetite ores have to be designed differently from flotation systems for the treatment of hematite ore. In magnetite flotation, the collector must be able to float mixed magnetite-silica grains; in hematite flotation, the typical need is
Four types of cationic collectors were tested and evaluated for their performance in the reverse flotation of silica from the spiral preconcentrate of Kudremukh iron ore. A stagewise flotation was conducted by adding the reagent in three stages. Starch was used to depress hematite.
A process for separating magnesite from its contaminants by a reverse flotation treatment of crushed magnesite ore which contains as its main constituents magnesium carbonate, and contaminants such as silica, generally silicate compounds of iron, aluminum and calcium, comprising the steps of

iron oxide from floating. This is commonly referred to as 'reverse' flotation. Normally silica is floated using an amine as the flotation reagent. But quot;reversequot; flotation using anionic collectors is also applicable to activated rock minerals (e.g., C2 activation
Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly decreases Fe in the silica-rich stream when used in combination with an amine (Lilaflot D817M).
The special feature of this invention is that cationic reagents of amine type which are effective froth flotation reagents for silica and the silicates, provoking in this way a reverse froth flotation process, in which the unaffected metallic mineral found in the tailing of a distinct pulp of mineral slurry represent the concentrate, a product
