Flocculant and collector were gently folded into the pulp with a spatula for a conditioning period of 2 minutes. The deslimed pulp was diluted to 23-percent-solids pulp density in a Fagergren laboratory flotation cell. The pulp was conditioned, for 2 minutes with 150 grams per ton (0.3 pound per ton) of insol slime blinder and for 2 additional ...

Abstract The low grade potash ores contain large amount of fine water insoluble minerals, which was defined as slime here. The removal of the slime from the low grade of potash ores (KCl < 10 %; slime > 40 %) from the Mahai Basin, Qinghai Province, PRC, was investigated using flotation. The characteristics of the slime sample, which …

The objective of this project was to compare the effect of a selective flotation frother (MIBC) and powerful frothers (DEMPH and DF-1012) on bubble size and ability in water and in brine. In water, the bubble size is clearly reduced by flotation frothers which prevent bubbles from coalescing.

The depressant can be selected to bind or otherwise interact with the clay portion of the potash/brine slurry such that a higher portion of the desired salt particles are floated in the flotation process. In the potash ore flotation process, in particular, water soluble, high molecular weight diallyl dialkyl quaternary ammonium polymers ...

The potash ore for laboratory flotation tests was acquired from Qinghai Salt Lake Industry Group Company in China. The samples were mainly composed of 71.32% halite, 24.97% sylvite, 2.94% clayey-carbonate impurities and 0.77% gypsum by the results of mineralogy analysis. The laboratory flotation tests were carried out in saturated …

Potash ore flotation is carried out in saturated sodium-potassium chloride (NaCl-KCl) brine (6–7 mol L –1 ), 1 which causes intense micelle formation and salting out of the collector. 2 The process of the influence of salt ions on the colloidal properties of …

In potash ore flotation, the flotation process carried out in 6–7 mol/L solution of NaCl and KCl, extremely high electrolyte concentration rises the Krafft point of the amine collector so much that this entirely changes amine mode of action. This insoluble in brine amphipathic compound forms molecular films at the brine/gas interface and is ...

On the basis of requirements developed for potash ore flotation depressant agents, a synthetic polymer called KS-MF and containing cationic functional groups has been developed. The use of the KS-MF depressant at the Uralkaly plant since 1999 has improved sylvite flotation within the saline solution temperature range of 18–37 °C and …

On the example of sylvinite ore enriched by direct flotation in ore-saturated solutions with a density of 1235 kg/m ³, it was shown that the use of a combination of frothers (pine oil ...

More than three quarters of the world potash are treated by flotation, in conjunction with leaching and crystallization processes to produce the final product quality. The direct flotation of potassium minerals is the common process employed worldwide. Two important factors for potash flotation are (a) the presence of clay in the ore and (b ...

Minus 0.10-m (4-inch) carnallite and minus 0.02-m (¾-inch) sylvinite ores were prepared for bench-scale flotation by stage-crushing and grinding through 1.70 mm (10 mesh) using a jaw crusher and roll crusher and then splitting the crushed ore into 1-kg (2.2-lb) charges. Stage crushing was used to avoid producing excessive fines, which …

Abstract. 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 ...

After size reduction, the potash ore is deslimed to remove any fine particles that may interfere with subsequent processing steps. This is typically done using hydrocyclones. Flotation. The next stage of processing is flotation, where the potash ore is treated with reagents to selectively separate the potash from the other minerals in the ore.

Flotation has been used in the potash industry since the 1940s, and nowadays, the majority (over 80%) of potash ore is processed by flotation [6]. Various surfactants (often called collectors) have been used to control the hydrophobicity of crystal surfaces and the selectivity of bubble-crystal attachment in the flotation separation of …

Potash ore must be crushed because the sylvite (processing target) crystals are intimately intergrown with halite at the cm scale and so must be released by breaking down ore to the appropriate size (usually less than 4–5 mm). ... In potash flotation, the aim is to separate sylvite from halite using cationic collectors interacting with ...

In a flotation process, frothers are utilized to enhance generation of fine bubbles and to stabilize the froth. According to Leja–Schulman's penetration theory, the interaction of frothers with a collector in the moment of the particle-to-bubble attachment is a vital step in the particle–bubble attachment. It is known that pure liquids do ...
