| Uralkali’s business is based on producing potash fertilisers, which are generally applied direct to soil or used to make compound NPK fertilisers. There are also some other industrial needs. We extract potash ore from the Verkhnekamskoye potassium and magnesium salt field at an approximate depth of 400 metres. We then process it at our surface enrichment plants. The extracted ore contains 25% to 35% of MOP. As a result of enrichment, mineral stock, which is a natural mixture of commercial component (MOP) and other substances (mainly sodium chloride and sludge), is transformed into concentrate, a finished product which is 90% MOP. |
