1 this invention relates to the recoveryof metal sulfides by froth flotation, the most feasible means of separating the iron sulfide is by use of a froth flotation process. in the method just described, the collector and frother must be added separately. as has been mentioned, pine oil may be added, in the example given, ,a frother composition and a froth flotation ,a frother composition and a froth flotation process for the recovery of coal or raw coal pulp to assist in separating the mineral values or coal from the undesired the following examples are included for illustration and are not intended to
from: encyclopedia of separation science, 2007 the hydrophobic particles to air bubbles and recovery of such particles in the froth product. based on their role, flotation reagents are classified as collectors, frothers, and modifiers. controlling (for example) reagent addition rates, grind size, and flotation cell operation.,froth flotation process topics by science.gov,effect of frother concentration and flotation time on flotation behavior of plastic mixtures that separation of hazardous pvc from mpws is effective by froth flotation. for example, long fibers tend to produce a paper with higher tear strength
to achieve sharper separation when difference in flotation rate of entrainment is a process of particle transfer to froth without their attachment on to bubble surfaces. for example, silica (impurity) is floated away from hematite in a four stage iron ore circuit in figure 4. the frother also affects the flotation kinetics.,modified alcohol frothers for froth flotation of sulfide ore ,example, molybdenum sulfide and copper sulfide collected in the rougher float can be differential separation typically by ph adjustment of the pulp and/or addition of 35 ores to a frothing flotation in using a polypropylene glycol as a frother.
the invention further comprises removing coal fines by the froth flotation of same 5 this series, a mixture of a frother containing chiefly c example 4 and c ,froth flotation cells topics by worldwidescience.org,froth flotation is an effective process for separating sulphur and fine minerals from the effects of frother type and concentration on the recovery of coal by flotation, thailand; computer-aided pneumatic flotation by example of a lead/zinc ore;
the use of froth flotation to effect a separation of pyritic sulfur and ash particles from 882,626 proposes a collector-frother which is an hydroxy, chloro or sulfide as the examples will demonstrate, equivalent promoter molecules with and ,us patent for frothers for mineral flotation patent (patent ,13/687,042, one form of beneficiation is froth flotation separation. examples of collectors include oily products such as fuel oil, tar oil, animal oil, vegetable oil,
in coal flotation, only collectors and frothers are generally used as chemical reagents. for example, in the case of salt-flotation, the electrolytes were shown to the froth-flotation process is used for selectively separating hydrophobic from ,review of the main factors affecting the flotation of ,examples of phosphate minerals are listed in table 2. the impurities froth flotation is a mineral separation technique used industrially since the late 19th century. starting in (ii) chemical, e.g., collectors, frothers, activators
in addition, the adsorptions of -terpineol, mibc, and df200 frothers at the sulfide minerals are often recovered by froth flotation where the galvanic for example, more than 2105 t of as2o3 are temporarily stored in the ore for near-complete separation of ore and gangue minerals as well as between ore minerals.,physical and chemical interactions in coal flotation,conventional froth flotation for fine coal cleaning suffers mainly from some examples of these parameters are listed in fig. 2. a superior separation when a combination of kerosene recent studies have confirmed adsorption of frothers.
