From some of the minerals like kainite, the potassium sulfate can be separated, because the corresponding salt is less soluble in water.

Gondia district is rich in mineral ores of manganese, iron, chromites, kainite, quartzite, caesium and vanadium.

Caesium chloride occurs naturally in mineral waters and as an impurity in carnallite (up to 0.002%), sylvite and kainite.

Mineral associations based on some physical properties but not limited to, are; halite, anhydrite, dolomite, gypsum, kainite, kieserite, polyhalite, and sylvite.

Boracite is typically found in evaporite sequences associated with gypsum, anhydrite, halite, sylvite, carnallite, kainite and hilgardite.

Kainite (MgSO KCl 3 HO) is a mineral salt that consists of potassium chloride and magnesium sulfate and is used as a fertilizer.

The sulfate is produced mostly by decomposition of the complex minerals kainite (MgSO KCl 3HO) and langbeinite (MgSO KSO).
