Natural Resources
The mineral form of potassium sulfate, arcanite, is relatively rare. Natural resources of potassium sulfate are minerals abundant in the Stassfurt salt. These are cocrystalisations of potassium sulfate and sulfates of magnesium calcium and sodium.
The minerals are:
- Kainite, MgSO4·KCl·H2O
- Schönite, K2SO4·MgSO4·6H2O
- Leonite, K2SO4·MgSO4·4H2O
- Langbeinite, K2SO4·2MgSO4
- Glaserite, K3Na(SO4)2
- Polyhalite, K2SO4·MgSO4·2CaSO4·2H2O
From some of the minerals like kainite, the potassium sulfate can be separated, because the corresponding salt is less soluble in water.
Kieserite, MgSO4·2H2O, can be combined with a solution of potassium chloride to produce potassium sulfate.

Famous quotes containing the words natural and/or resources:
“If everybody is looking for it, then nobody is finding it. If we were cultured, we would not be conscious of lacking culture. We would regard it as something natural and would not make so much fuss about it. And if we knew the real value of this word we would be cultured enough not to give it so much importance.”
—Pablo Picasso (1881–1973)
“I am willing to pledge myself that if the time should ever come that the voluntary agencies of the country together with the local and state governments are unable to find resources with which to prevent hunger and suffering ... I will ask the aid of every resource of the Federal Government.... I have the faith in the American people that such a day will not come.”
—Herbert Hoover (1874–1964)
