INTRODUCTION
Polyhalite is indeed a mineral that is naturally occurring and mined in certain locations including the United Kingdom. Polyhalite is a mineral that forms in evaporite deposits. These deposits are typically found in regions where there is a history of evaporation of seawater or brines, leaving behind various salts and minerals. Polyhalite is mined in the UK from a layer of bedrock located over 1000 meters below the North Sea off the North Yorkshire coast. The deposits in this region are well-known and have been commercially exploited. Polyhalite is not a mixtures of salts; rather, it is a specific mineral with a defined chemical composition. It's chemical formula is K2Ca2Mg(SO4)4·2H2O. This formula indicates that polyhalite is a complex salt containing potassium (K), calcium (C), magnesium (Mg), sulfate (SO4) and water molecules (H2O). Polyhalite is characterized by its unique crystal structure. It forms as a single crystal complex, meaning that it's constituent elements are arranged in a specific and repeating pattern within a single crystal lattice. Polyhalite contains two molecules of water of crystallization within it's crystal structure. This water is chemically bound to the mineral and is an integral part of it's composition. hio
