This week’s photo shows four distinct potash samples that were agglomerated in the FEECO Innovation Center.
Each sample varies in color, depending on both mining location and binder used during processing. Potash is commonly mined in Canada and parts of the United States, with colors varying from location to location, depending on the amount of iron present in the deposit. When processing potash, a binder is often used during pelletization, and occasionally during compaction. Binder selections may alter the physical color, thus another reason why the four samples are differing shades of red.
The potash samples also vary in shape, depending on the agglomeration method used for processing. The sample on the top right was pelletized, while the other three were compacted. Pelletization produces pellets, as the name suggests, with a round and smooth exterior. Compaction, on the other hand, produces granules, more angular in shape.
