C05BPHOSPHATIC FERTILISERSThe following IPC groups are not in the CPC scheme. The subject matter for these IPC groups is classified in the following CPC groups: C05B21/00covered by C05B1/00 - C05B19/00 (see internal note after the title of class C05)In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme. C05B1/00 C05B1/00Superphosphates, i.e. fertilisers produced by reacting rock or bone phosphates with sulfuric or phosphoric acid in such amounts and concentrations as to yield solid products directly C05B1/02Superphosphates C05B1/04Double-superphosphateTriple-superphosphateOther fertilisers based essentially on monocalcium phosphate C05B1/06Ammoniation of superphosphates fertilisers based essentially on ammonium orthophosphate C05B7/00 C05B1/10Apparatus for the manufacture of superphosphates C05B3/00Fertilisers based essentially on di-calcium phosphate C05B11/00 takes precedence C05B5/00Thomas phosphateOther slag phosphates C05B7/00Fertilisers based essentially on alkali or ammonium orthophosphates C05B11/00 takes precedence C05B9/00Fertilisers based essentially on phosphates or double phosphates of magnesium C05B11/00 takes precedence C05B11/00Fertilisers produced by wet-treating or leaching raw materials either with acids in such amounts and concentrations as to yield solutions followed by neutralisation, or with alkaline lyes C05B11/02Pretreatment C05B11/04using mineral acid C05B11/06using nitric acid (nitrophosphates) C05B11/08using sulfuric acid C05B11/10using orthophosphoric acid C05B11/12using aqueous hydrochloric acid C05B11/14using wet gaseous acids C05B11/16using alkaline lyes C05B13/00Fertilisers produced by pyrogenic processes from phosphatic materials C05B13/02from rock phosphates C05B13/06 takes precedence C05B13/04from metallic phosphorus compounds, e.g. ferro-phosphorus C05B13/06Alkali and alkaline earth meta- or polyphosphate fertilisers C05B15/00Organic phosphatic fertilisers bone meal C05B17/00 C05B17/00Other phosphatic fertilisers, e.g. soft rock phosphates, bone meal C05B17/02containing manganese C05B19/00Granulation or pelletisation of phosphatic fertilisers, other than slag granulating apparatus B01J2/00; granulating slag C04B C05B19/02of superphosphates or mixtures containing them
