artical on iron ore reverse floation process

In iron ore direct flotation process a sort of direct flotation reagent is added and then works under specific conditions The floating material is mainly iron concentrate On the contrary iron ore reverse flotation uses reverse flotation regents to work under given conditions and its floating material is mainly gangue mineral Because the 2 1 2 Reverse flotation process Liu Yuntao[5] invented a coarse-grain reverse flotation method for phosphate ore which is characterized in that the low grade phosphate ore is crushed and grinded and flotation feed size is of -0 074mm less than 50% and then put it into the flotation tank with the pulp

Beneficiation of iron ore fines by conventional flotation

Reverse flotation process was adopted wherein gangue minerals silica and alumina were floated using cationic amine collector Sodium hydroxide and starch were used to regulate the slurry pH and to depress iron ore respectively Various iron ore samples drawn from different mines and their mixtures were subjected to the test work Results of

The present investigation deals with the recovery of iron values from the screw classifier overflow slimes from an iron ore washing plant by means of reverse cationic flotation as an alternate to direct anionic flotation Selectivity index an indicator of separation efficiency was chosen as the response parameter for optimizing the quantity and evaluating a series of generically same but

Research regarding iron ore flotation began in 1931 demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation Several studies describing the processing of iron ores via reverse cationic flotation are

Reverse flotation was adopted for Indonesian iron-rich laterite ore from Pomalaa to float siliceous minerals in the separation of iron mineral Nickel siliceous mineral such as garnierite is one of the silicate minerals containing in laterite ore that are undesirable and must be eliminated from the ore before used as raw material for iron making industry Calcine laterite product was obtained

The main mechanism of the reverse flotation of quartz from iron ore is based on the electrostatic theory of flotation This is due to the strong pH dependence of the zeta potential of the mineral edge planes on silicate particles (Fuerstenau and Pradip 2005) An electrical double layer (inner and outer Helmotz planes) as illustrated in Figure 1 forms on the surface of particles submerged

Flotation Reagent Magnetic Seperation Efficient

Reverse flotation process was adopted wherein gangue minerals silica and alumina were floated using cationic amine collector Sodium hydroxide and starch were used to regulate the slurry pH and to depress iron ore respectively Various iron ore samples drawn from different mines and their mixtures were subjected to the test work Results of

Iron Ore Processing for the Blast Furnace blast furnace process The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets in much the same manner that one rolls a snowball to make a pellet about the size of a marble (between 1/4 and 1/2

Desliming prior to the reverse cationic flotation of iron ores was introduced with the USBM process (Clemmer 1947) An adequate degree of dispersion of the particles in the pulp is a requisite for efficient desliming A simple and inexpensive way of reaching a high dispersion degree is raising the pH with the use of large amounts of NaOH increasing the electrostatic repulsion among the
