Note(s) The following notes are meant to assist in the use of this part of the classification scheme; they must not be read as modifying in any way the elaborations. In this sub-section, the separation of different materials, e.g. of different matter, size, or state, is predominantly found in the following subclasses: Fulltext... Hierarchy... Expanded...B01D Fulltext... Hierarchy... Expanded...B03B, Fulltext... Hierarchy... Expanded...B03C, Fulltext... Hierarchy... Expanded...B03D Fulltext... Hierarchy... Expanded...B04B, Fulltext... Hierarchy... Expanded...B04C, Fulltext... Hierarchy... Expanded...B07B, Fulltext... Hierarchy... Expanded...B07C. The classifying characteristics of these subclasses are: the physical state of the matter to be separated; the principle of the process used; particular kinds of apparatus. The first of these characteristics involves six different aspects, assembled in three groups: liquid/liquid or liquid/gas and gas/gas; solid/liquid or solid/gas; solid/solid. These subclasses are to be used according to the following general rules: Fulltext... Hierarchy... Expanded...B01D is the most general class as far as separation other than solids from solids is concerned. Apparatus for separating solids from solids are covered by Fulltext... Hierarchy... Expanded...B03B when the process concerned is regarded as the equivalent of "washing" in the sense of the mining art, even if such apparatus is a pneumatic one, especially pneumatic tables or jigs. Screens per se are not covered by this subclass but are classified in Fulltext... Hierarchy... Expanded...B07B, even if they are being used in a wet process. All other apparatus for the separation of solids from solids according to dry methods are classified in Fulltext... Hierarchy... Expanded...B07B. If the separation takes place as a result of the detection or measurement of some feature of the material or articles to be sorted it is classified in Fulltext... Hierarchy... Expanded...B07C. It should also be noted that the separation of isotopes of the same chemical element is covered by Fulltext... Hierarchy... Expanded...B01D 59/00, whatever process or apparatus is employed. The following scheme illustrates the classification according to these rules.

|  | B09 |
DISPOSAL OF SOLID WASTE; RECLAMATION OF CONTAMINATED SOIL (treatment of waste water, sewage or sludge Fulltext... Hierarchy... Expanded...C02F; treating radioactively contaminated solids Fulltext... Hierarchy... Expanded...G21F 9/28) [3,6]

|  | B09C |
RECLAMATION OF CONTAMINATED SOIL (gatherers for removing stones or the like from the soil Fulltext... Hierarchy... Expanded...A01B 43/00; sterilising soil by steam Fulltext... Hierarchy... Expanded...A01G 11/00; separation in general Fulltext... Hierarchy... Expanded...B01D; cleaning beaches Fulltext... Hierarchy... Expanded...E01H 12/00; removing undesirable matter, e.g. rubbish, from the land Fulltext... Hierarchy... Expanded...E01H 15/00) [6]

|  | B09C |
Note(s) In this subclass, the following term is used with the meaning indicated: [6] "reclamation" means the partial or total elimination or the fixing of contaminants in soil. [6] Processes using enzymes or micro-organisms in order to: [6] liberate, separate or purify a pre-existing compound or composition, or to [6] treat textiles or clean solid surfaces of materials [6] are further classified in subclass Fulltext... Hierarchy... Expanded...C12S. [6]

|  | B09C 1/00 - B09C 1/00 |
Note(s) In groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B09C 1/00-B09C 1/10, it is desirable to add the indexing code of group Fulltext... Hierarchy... Expanded...B09C 101/00. The indexing code should be unlinked. [6]

Reclamation of contaminated soil [6]

· | Extraction using liquids, e.g. washing, leaching [6]

|  | B09C 1/04 |
· | Flotation [6]

|  | B09C 1/06 |
· | thermally (incinerators for contaminated soil Fulltext... Hierarchy... Expanded...F23G 7/14) [6]

|  | B09C 1/08 |
· | chemically (chemical means for combatting harmful chemical agents Fulltext... Hierarchy... Expanded...A62D 3/00) [6]

|  | B09C 1/10 |
· | microbiologically or by using enzymes [6]

Indexing scheme associated with groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B09C 1/00-B09C 1/10, relating to the reclamation of contaminated soil. The indexing code should be unlinked. [6]

Note(s) Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6]
