Production Of Potash From Kiln Dust Of A Cement Plant In
How is Potash Processed? | Canpotex
The majority of fertilizer grade potash is processed using flotation processing. A second method, crystallization, is used mainly to produce Industrial and specialty-grade (white) potash. In both methods, impurities are removed from the potash ore, and the size of granules can be changed, but the final product is the same naturally-occurring mineral as was originally mined.

The kiln's operating temperatures (in excess of 2,600 F) cause the cement materials to react and form the final product – Portland cement. Flue gases from the kiln's burners pass through the ESP, which uses high voltage electrical wires to impart a negative charge to the dust particles which are then attracted to positive (grounded) plates.
