A typical example of such environments is the solar saltern, where seawater is evaporated to produce sea salt. Calcite (CaCO 3), gypsum (CaSO 4 ·2H 2 O), halite (NaCl), sylvite (KCl), and finally carnallite (KCl·MgCl 2 ·6H 2 O) precipitate out sequentially as the evaporation occurs. As a consequence, the final proportional composition of a ...

Thus, the mineral evaporite precipitate sequence of seawater is well known: calcite (or aragonite); gypsum (or anhydrite), halite, sylvite and carnallite. Consequently, the chemistry of the residual waters reflects both concentration due to progressive removal of water as well as the removal of the solutes that make up the evaporite minerals.

The method of preparation of the carnallite for the electrolysis includes reduction of the carnallite ore, its air separation with partition of the carnallite and the halite, the two-stage dehydration of the carnallite. After reduction the carnallite ore is subjected to dressing within two stages in series: at first using the air separation in ...

Carnallite crystallizes in the orthorhombic system and usually forms granular aggregates with halite, sylvite, and other salt deposit minerals. It is colorless or tinted murky brown, reddish pink, and other colors as a result of impurities contained in it. Carnallite is hygroscopic and characterized by a bitter salty burning taste.

The structure of water on carnallite surface is not stable, which allows DMP direct contact with carnallite surface at a smaller adsorption energy of -37.97 kJ·mol -1. Because of the difference in adsorption energies of DMP with the two minerals, we assumed that DMP preferentially adsorbs on halite surface in the flotation process.

Carnallite recovery by reverse flotation of halite with dodecyl morpholine (DDM) as collector has been applied in industry. Despite successful use in industry, the surface chemistry for halite flotation with DDM collector is not clear. Therefore the major objective of this thesis research was to examine the flotation chemistry in detail and understand the nature of the interaction …

Carnallite, with the chemical formula KMgCl 3.6H 2O, is a mineral that was first discovered in the Urals Mountains in Russia. The reverse flotation has been established for carnallite processing in the current decades, and the alkyl morpholine collector is used for the removal of NaCl from carnallite using the reverse flotation. The carnallite

The most common minerals that are generally considered to be the most representative of marine evaporites are calcite, gypsum and anhydrite, halite, sylvite, carnallite, langbeinite, polyhalite, and kainite. Kieserite (MgSO4) may also be included, which often will make up less than four percent of the overall content.

The salinity of the interstitial solution gradually increases with decreasing distance to the sediment/atmosphere interface leading to the sequential precipitation of gypsum (CaSO 4 · 2H 2 O), halite (NaCl), carnallite (KMgCl 3 · 6H 2 O), and possibly sylvite (KCl) and bischofite (MgCl 2 · 6H 2 O). The presence and depth of these salts in ...

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.

Anion concentrations were measured using ion chromatography to estimate salt removal. EC-based measurements showed ~8-10% removal efficiency in the …
