potashbrine

Potash brine refers to an aqueous solution containing dissolved potassium salts, most commonly potassium chloride (KCl), that is produced from underground potash deposits or evaporite beds. It serves as a feedstock for the production of potash fertilizers and related potassium products. Potash brine can form when potassium-bearing minerals such as sylvite (KCl) or carnallite (KMgCl3·6H2O) dissolve in water within salt beds, or when mined ore is processed to extract soluble salts.

The composition of potash brine varies by deposit and processing method, but typically includes potassium ions

Production methods include solution mining and direct brine extraction. In solution mining, water is pumped into

Applications are primarily agricultural, with potassium fertilizers supporting plant growth and crop yields. Environmental considerations center
