· crystals of potash and salt in the ore. Clay particles are separated from the crystals using agitation machines. The clay particles are much smaller than the potash and salt crystals and are removed using size separators. Flotation Process reagents added to the potash, salt and brine mixture attach only to the potash crystals.
Chemistry 30: Chemical Equilibrium
Ore: Is rock that contains important minerals including metals. The ore is extracted through mining and processed to extract the valuable element(s). Ore contains minerals that can be mined at a profit. Potash: Is Saskatchewan's provincial mineral. Potash is the common name for the potassium rich ore mined in Saskatchewan.

Potash - Wikipedia
Potash (/ ˈ p ɒ t æ ʃ /) includes various mined and manufactured salts that contain potassium in water-soluble form. The name derives from pot ash, which refers to plant ashes or wood ash soaked in water in a pot, which was the primary means of manufacturing the product before the Industrial Era.The word "potassium" is derived from "potash". Potash is produced worldwide …

WHAT IS POTASSIUM CHLORIDE?
potash ore is sylvinite, which is a mixture of halite ∼ 60% (sodium chlo-ride or NaCl), sylvite ∼35% (potassium chloride or KCl), and clay (and other water - insoluble minerals) ∼ 5%. The concentration of the miner-als in sylvinite can vary signifi cantly depending on the location of the potash ore. SASKATCHEWAN POTASH HISTORY

Concentration Ratio is the Key When looking at different potash projects, particularly those involving underground mining, a key economic factor is the concentration ratio. This ratio represents the tonnes of potash ore needed to produce a tonne of final saleable product. Typically the final potash product has a grade of 60% K2O.
