Froth flotation is widely used for separating KCl from NaCl and other undesirable components such as carnallite and gangue in the beneficiation of potash. Because the flotation process relies on the hydrophobic and hydrophilic interactions between materials, however, enhancing these relationships is essential to maximizing potash recovery.
The invention relates to a flotation process for removal of slimes from potash ores wherein a collector is used which is a propoxylated ethoxylated fatty amine having the formula I wherein R1 is a hydrocarbyl group having 8-24 C-atoms, the sum of all m is on average 2-6, and the sum of all n is on average at least 15 and at most 100.
Potash grades ranged from 7.2 to 22.2 K20 and recoveries by crystallization ranged from 85 to 99. Sylvite flotation from chloride evaporites with amine collector recovered 90 to 97 of the potash in a concentrate containing 54.3 to 60.3 K2o.
A collector composition especially suitable for the coarse flotation of sylvinite comprising A at least about 90 percent by weight of a primary aliphatic amine of 16-18 carbon atoms, or water soluble salts thereof and B about 0.5-10 percent by weight of a primary aliphatic amide of 10-20 carbon atoms.
2006-10-12A potash ore processing method for the recovery of potassium minerals from potash ore can comprises conditioning a pulped potash ore, wherein the potash ore comprises a potassium chloride component and a clay component, in a saturated brine solution with an effective amount of brine dispersible urea-formaldehyde resin or modified brine dispersible urea-formaldehyde resin.
2020-2-19KCl from NaCl. In the second way at first flotation would float NaCl from carnallite with an alkyl-morpholine collector and then KCl would be separated by cold decomposition of carnallite to produce KCl 8. This paper is confined to the second strategy. Processing Steps The inputs to the plant, according to the amount of potash
2019-7-25Thus flotation of potash in saturated brine solution has been implemented instead. At present, over 75 of the potash production worldwide comes from cationic flotation with amine as collector. Especially, the flotation of sylvite by using primary aliphatic amine with hydrocarbon chain length of C 16-C 18 is practically done. ...
Frothers Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process Reduce surface tension of the liquid-gas interface to enable froth formation Hinder coalescence in order to stabilize bubble size
2010-12-21Flotation rate data are used to estimate the necessary retention time for a flotation circuit 34, to scale up flotation cells 29, and to model flotation circuits for process optimization 35-36. Collectors The collector may be adsorbed on a mineral by chemical or physical forces.
Flotation of potash was developed in the early 1930s. Amines are widely used for flotation of sylvite KCl from halite NaCl and insoluble materials such as clays. Amine collector is also absorbed by clays.
The most common collector flotation reagent used in the flotation process are long chain aliphatic amines. Temperature variations have adverse effect on the physical, chemical and physicochemical properties of amine dispersion, viscosity of the brine solution, dissolution and adsorption of the amine as well as the wettability of the potash ...
2011-2-11The flotation circuit consists of 8-14.2 m cell rougher and scavenger banks with the froth concentrates from each stage combined to feed the water leach section of the potash plant. The flotation tails flow to a holding pond for reintroduction to the evaporation pond system and salt recovery. During the early flotation development
Potash grades ranged from 7.2 to 22.2 pct K2O, and recoveries from 84 to 99 pct. Sylvite flotation from chloride evaporites, with amine collector, recovered 90 to 97 pct of the potash in a concentrate containing 54.3 to 60.3 pct K2O.
Our range of flotation solutions include frother and collector programs for coal, copper, molybdenum, phosphate, potash, and more. All of our solutions address your process holistically, helping you optimize your flotation circuit to achieve greater selectivity, recovery, grade, and ultimately, cost performance.
Potash is the most important source of potassium in fertilisers. Flotation is one of the major methods to upgrade the potash. We are the world-leading supplier of collectors to the potash industry. For the direct flotation of potash, we can deliver either standard amine produced from different types of fatty acids or special formulations.
2020-5-22AkzoNobel is a leading global supplier of flotation reagents and collectors for industrial minerals and iron ore applications. It says it has gained its leadership position by being at the forefront of the advanced colloid and surface chemistry upon which successful flotation depends a position it has achieved with more than 40 years of research and development in molecular and surface ...

The rougher flotation behaviour of Potash ore from the Potash Corporation of Saskatchewan was evaluated in both laboratory batch and continuous cells by the use of experimental designs. Data obtained in all tests were adjusted statistically and then used to estimate the parameters of proposed kinetic models. By means of statistical and physical significance criteria, the Beta distribution ...

The Canadian Journal of Chemical Engineering, published by Wiley on behalf of The Canadian Society for Chemical Engineering, is the forum for publication of high quality original research articles, new theoretical interpretation or experimental findings and critical reviews in the science or industrial practice of chemical and biochemical processes.
The modern processing of sylvinite and other potash ores is usually a comparatively simple and standardized procedure, practiced in much the same way at most potash plants. In the early days of the industry, and still with some operations having complex ores or to process fines or waste streams, the ore was given a hot leach, the undissolved ...
