According to some embodiments there is provided a process for the recovery of SOP from Sulphate bearing mineral and Carnallite or Sylvenite, comprising: Dissolving Carnallite in water to obtain Sylvenite and high Magnesium Chloride brine; Adding Sodium Sulphate to said Carnallite to produce mixture of Kainte\Leonite, KCl and NaCl precipitant and brine containing Mg Cl, KCl, NaCl; Separating the NaCl from the mixture; Obtaining a precipitant mixture of Leonite with KCl; Filtering said Leonite and washing with water to yield pure mixture of Leonite with KCl; Adding KCl to the Leonite with the KCl; and Decompose said Leonite with the KCl to SOP.

Process for the production of potassium sulphate and magnesium sulphate from carnallite and sodium sulphate

There is provided herein a process for the compaction of Polyhalite with a Potassium salt, wherein said process comprising: mixing a feed of polyhalite with a feed of said Potassium salt in a mixer to yield a mixture; compacting said mixture in a compactor to yield masses; crushing said masses in a crusher to yield particles; screening said particles in a screener to yield fine particles in three different sizes: oversized fine particles which undergo a second crushing process and are retuned to said screener for screening, undersized fine particles which are transferred to said mixer for further mixing, and desired size fine particles which are transferred to a polish screener glazing, drying and oiling.

Compaction of polyhalite and potash mixture

There is provided herein a process for the production of polyhalite granules from fine dry polyhalite powder comprising preparing a binder-water mix and mixing the binder-water mix with the polyhalite powder in a mixer, continuously adding water to the mixer to provide a polyhalite material, discharging the polyhalite material from the mixer and introducing the material into a fluid bed, drying the material and screening the material to receive granules ranging in size between 1.4 mm to 4.75 mm.

Polyhalite granulation process

According to some demonstrative embodiments, there is provided herein a spherical fertilizer granule having a specific gravity of more than 1.94 g/cmand less than 3% porosity.
