Abstract: There is provided herein a granule comprising Polyhalite and phosphogypsum, in a ratio of between 40:60 to 60:40, respectively.

Abstract: There is provided herein a granule comprising polyhalite in a concentration of between 20-80% w/w and urea in a concentration of between 20-50% w/w and optionally a binder, wherein said granule comprises a granule strength of at least 1.1 Kg/ granule.

Abstract: According to some embodiments, there is provided herein a fertilizer granule comprising Polyhalite and Sulphate of Potash (SOP), wherein the granule comprises a granule strength of at least 0.5 Kg/granule.

Abstract: According to some embodiments, there is provided herein a fertilizer granule comprising Polyhalite and Ammonium Sulphate, wherein said granule comprises a concentration of 40-60% w/w Polyhalite and 60-40% w/w of Ammonium Sulphate.

Abstract: According to some demonstrative embodiments, there is provided herein a fertilizer granule comprising Polyhalite and potassium sulphate, wherein said Polyhalite is present in a concentration of 30-70% w/w and said Potassium Sulphate is present in a concentration of 70-30% w/w, wherein the strength of granule immediately after production 1.3 Kg granule.

Abstract: According to some embodiments of the present invention there is provided herein a compacted granule of Polyhalite, Potassium salt and an inorganic binder comprising a strength of 2.7 KgF/Granule when measured after production.

Abstract: There is provided herein a process for the compaction of Polyhalite, comprising: mixing a feed of polyhalite with an inorganic binder 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; and screening said particles in a screener to yield 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 compacting, and desired size fine particles which are transferred to a polish screener for glazing and oiling.

Abstract: According to some embodiments there is provided herein a granule of potash dust comprising a binder selected from the group including Flyash, Sodium Silicate, Potassium Silicate and starches, wherein said potash dust comprises particles in the size between 0.001-0.
