Plant operations in the SOP Wet plant. Harvest the SOP feedstock, crush it and feed it into the plant where it is mixed with brine to form a slurry. It is then agitated, cooled, crystallized, thickened and filtered to produce an intermediate product called schoenite. The schoenite is then converted to SOP in an equilibrium process where it is re-slurried with different brine, heated, crystallized as SOP, filtered and dried. It is then compacted and screened into various grades of product.
