Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation, less is more! Over 2 years ago I wrote about
A selective or sequential flotation flowsheet of two or more products. By utilizing selective flotation, two or more minerals in an ore are separated into individual high grade products. ORE TREATED: The most common of ores treated in this manner are lead zinc, copper-zinc-iron, copper-nickel, but application may be made to other two or three mineral separations. This flowsheet, without a Unit
5 Types of Phosphate Froth Flotation Process. Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies.
flotation selectivity. The combination of the foaming power ® of the Lupromin® FP A 711 and its chemistry promotes the necessary selectivity for the flotation process. Collector is supplied as a viscous liquid at room temperature. Lupromin® FP A 212 is a fatty acid based collector applied for oxidized phosphate ore flotation.
If native gold is present, dithiophosphates can be used which are less selective to iron sulphides. Increasing and controlling the pH within the flotation vessel to between 10 and 12 causes the process to become more selective, away from iron sulphide gangue minerals such as pyrite to produce a cleaner copper mineral concentrate.
It proves that both selectivity and power of frothers are useful parameters for characterizing flotation systems.

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.
AbstractArtificial neural network was used to predict the copper ore flotation indices of Separation Efficiency (SE) and Selectivity Index (SI) within different operational conditions. The aim was to predict SECu and SIFe and SIMo as a function of chemical reagent dosages (collector, frother, modifier), feed rate, solid percentage, and the feed grade of Cu, Fe, and Mo.

Flotation reagents adsorb on targeted mineral surfaces, making those hydrophobic. Choice and selection of the appropriate reagent chemistry is important for achieving the desired mineral recovery and selectivity. Additional chemicals are important for modifying the mineral surfaces and so control flotation selectivity and recoveries.
Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.
