Sylvite | SpringerLink
Abstract. The most characteristic mineral source of potassium is sylvite (KCl). Nevertheless, it is frequently observed associated with halite (NaCl), forming the mix known as sylvinite. In most cases, relatively pure sylvinite essentially has no soluble sulfate or other salts. It can occasionally be associated with carnallite (KMgCl 3 ·6H 2 0 ...
What is potash?
Potash is the name for the group of minerals that provide potassium for plant growth. It is a 'must have' fertiliser for crop production. 90-95% of potash is used in agriculture as fertiliser. The most common type of potash is Muriate of Potash (MoP) which is used to maintain soil fertility and improve plant health.
