Jun 01, 2021 Potash is normally found in underground deposits, 700-1,400 metres deep. Potash ore contains generally between 20 and 35% KCl, the remainder being NaCl, Mg-salts, etc. There are two basic types of potash mining: conventional mining, which encompasses several standard methods, modified as necessary for specific situations, and solution mining.

Due to the presence of insolubles such as dolomite, anhydrite, and clay adjacent to the underground seams of potash ore, these insolubles attach themselves to the potash particles as impurities. Scrubbing is the process of adding brine to crushed ore in a series of agitated tank cells to dislodge these impurities from the potash.

Potash deposits, which are located at fixed positions and depths of up to 1400 m, are extracted by mechanised methods of underground mining. When underground extraction is no longer feasible due to the depth of the deposits and/or when water inflow problems hinder conventional underground mining, the extraction of salt domes is used.
