It was established that the enrichment of polyhalite-halite ore is possible by the method of reverse flotation using alkylmorpholine as a collector. It was established that high levels of enrichment of polyhalite-halite ore (recovery of halite 95.41 %) are achieved at high dosage of the collector (1600 g/t).
Sylvite & Halite Flotation – Salt Mineral Collectors The flotation of sylvite (KCl) and also some accessory minerals (e.g. kieserite, langbeinite) from crude potash salts are processes used to a large extent all over the world.

The reagent was used as received and without further purification.
The flotation behavior of halite has been studied using an alkyl-morpholine as collector by some Chinese researchers (Zhang and Song, 2006). They try to explain the adsorption mechanism but the conclusions are uncertain. They also observed that the addition of frother increased the adsorption density as Titkov had observed. Despite …
The developed reagent schemes for halite flotation allowed us to consider the possibility of this process for preliminary beneficiation of potash (sylvinite) ores, represented by a mixture of sylvite (KCl), halite and clayey-carbonate impurities.

XRD results show that halite of > 99% purity was produced after the flotation of burkeite and trona. Furthermore, soda ash and sodium sulfate were produced after the second evaporation process by a combination of flotation, carbonation, and calcination techniques. Sodium chloride is the most abundant and feasible product.
Among the influencing factors shown in Fig. 1, particle size is the most important [[9], [10], [11]].Froth flotation works best when minerals are in an intermediate particle size range, typically from 20 to 150 μm, but varies with the types of minerals [[10], [11], [12]].When particles are smaller than about 20 μm, value mineral recovery and …

to flotation researchers for many decades. In 1933, Halbich proposed that the flotation of halite from sylvite with carboxylic acid is due to the preferential formation of sodium carboxylates, which are less soluble than potassium carboxylates (Halbich, 1933). Later investigation by Singewald

It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration
The densities of halite and calcite are fairly close neighbors on the scale, which makes it an interesting point of discussion. Halite, with its density of around 2.17 g/cm³, isn't that far off from calcite's approximate density of 2.71 g/cm³. Imagine two boxes of the same size: one filled with halite and the other with calcite.
The flotation results indicated BMBD had higher flotation recovery and stronger affinity of halite against carnallite compared with conventional monomeric surfactant N-(n-Dodecyl) morpholine (DDM). Fourier transform infrared spectra suggested that BMBD molecules were adsorbed on halite surface rather than the carnallite surface.
