Kieserite lends its name to a group of sulfates called the Kieserite Group. These sulfates are all monoclinic, have medium sized cations and are mono-hydrated (one water molecule). The general formula of this group is ASO 4 - H 2 O, where A can be either magnesium, iron, copper, manganese, nickel and/or zinc. These are the members of the ...

mineral kieserite, which is extracted during underground mining of sylvinite. After mining, the kieserite is separated from the NaCl residues using "electrostatic separation" – a patented, environ - mentally friendly, dry separation process. The ESTA Kieserit obtained in this way can be used directly as a fertiliser on your field.
Discover a potentially efficient process to convert dolomite into kieserite-like fertilizer. Boost magnesium content and enhance plant growth. Field-tested and proven effective for cocoa and oil palm.
Yet, a large-scale epsomite making employs commercially kieserite material or known as MgSO4.H2O (Figure1). Kieserite is less soluble in cold water. Heating such a material will change it into its anhydrate form and when the solution reaches its saturation point, cooling process bears epsomite crystal (Soin and Wilson, 1963; Taylor, 1960).
However, natural kieserite cannot be found in Indonesia. The fact that this country retains a lot of dolomite deposits and such a material can be processed into synthetic kieserite by sulphatization process seems promising for fertilizer industry in Indonesia.
In the A substrate, the increase of Mg loading resulted from an exchange process with Ca, whereas it was achieved at the expense of exchangeable Al in the B substrate. Calcium and Mg losses from the soil columns after 32 d were greater with kieserite than with dolomite. These losses were also larger for the hemi‐organic A …
deficiency, dolomite is often used to replace kieserite although the former is less reactive than the later. An activation technology by heating up to 800oC, followed by sulfic acid addition, then enriched by phosphate solubilizing bacteria is prospective to improve Mg solubility in soils. This
It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg …
The purpose of this study is to synthesize kieserite fertilizer from magnesite ore as raw material with addition of sulphur and to see whether the composition of prepared product meet the specification of kieserite fertilizer as stated in SNI 02-2807-1992.

Natural kieserite is usually used for the production of epsom salt and fertilizer. Normally, the mineral is mined from geologic marine deposits and provides a soluble source of both Mg and S for plant nutrition. However, natural kieserite cannot be
conducted to assess the process of kieserite fertilizer formation from magnesite ore and solid sulphur so that these produced kieserite fertilizers could conform to SNI 02-2807-1992 [1] to increase products added value. Some previous studies have been done on the process of kieserite fertilizer formation with various materials and methods [8,9].
Dissolution of dolomite attenuates the acidity generated by pyrite oxidation, thereby releasing calcium and magnesium to form gypsum [CaSO 4 ·2H 2 O], simple magnesium salts, and more complex ones such as magnesiocopiapite [Mg Fe 4 3 + (SO 4) 6 (OH) 2 …
In this study, five Mg-fortified mono-ammonium phosphate (MAP) fertilizers were produced with anhydrous magnesium sulfate (MgSO 4) and dolomite (CaMg (CO 3) 2) in various ratios. Nutrient solubility, Mg nutrient release, Mg leaching, and agronomic …

(Shimadzu, Kyoto, Japan). Magnesite and dolomite were finely ground to below 5µm. The scanning rate was set at 2 /min within the range between 10 and 90 . The XRD results of magnesite and dolomite are presented in Figure1where it can be seen that both magnesite and dolomite samples have high purity and almost no impurity peaks. …
