Advantages and Disadvantage of Froth Flotation Method

 · Froth flotation method is a kind of mineral processing technology that the solid minerals emerge from water suspension (slurry) according to the physical and chemical properties of the mineral surface.. According to statistics, more than 60% ~ 70% ore in the world is separated by froth flotation method, involving more than one hundred kinds of minerals.

 · Influence of Chitosan Dosage on the Flotation Performance Sulfide Minerals. Four different dosages of chitosan polymer were used in the flotation experiments: 50, 100, 300, and 500 g/ton. As reported in literature, these dosages were used when polymers such as polyacrylamide (PAM) and its derivatives were applied in sulfide mineral flotation .

and heavy minerals contents in the sunk. Flotation is a complex process with multiple factors that may influence the minerals purifiion. In this study, as the majority of variables associated with froth flotation are difficult to change in the industrial process : size of the flotation cells, impellers speed,

flotation refining minerals

Flotation Metallurgist Mineral Processing Engineer. What Ore is Suitable for Flotation. The largest class of ores treated by the flotation process consists of those containing the sulphide minerals of copper ; these sometimes contain native copper and also gold and silver, all of which can generally be floated with the sulphide minerals

Interactive effect of minerals on complex ore flotation: A ...

Froth flotation is the most effective industrial method used to separate finegrained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores ...

the ions of the mineral surface to form an insoluble metal chelate, to which the hydrocarbon oil which is necessary to ensure flotation adheres by physical adsorption. They described 8hydroxy quinoline (Rinelli and Marabini, 1973), cupferron (Marabini and Rinelli, 1973), salicylaldehyde (Marabini, 1975) as collectors for various oxide minerals.

Kinetics of ore flotation

 · Flotation kinetics (from the Greek Kinētikós – driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, R = f (t).

EFFECTS OF EDTA ON SELECTIVE FLOTATION OF SULPHIDE MINERALS

copper minerals (mainly chalcopyrite) hampers flotation selectivity. Galvanic interaction between the sulphide minerals is considered as the main cause for such activation. Therefore, a complexing agent, EDTA, was used to prevent unwanted activation of sphalerite and pyrite by copper ions in the presence and absence of collector.
