Potash. Large salt crushing mills at a factory producing potash. Potash consists of potassium salts, mainly chloride, that are sequentially deposited in inland marine environments along with common salt. The salts have to be crushed so the potassium salts can be removed for processing into fertilisers. Photographed in Belarus.
