SECTION B – PERFORMING OPERATIONS; TRANSPORTING


B 03SEPARATION OF SOLID MATERIALS USING LIQUIDS OR USING PNEUMATIC TABLES OR JIGS; MAGNETIC OR ELECTROSTATIC SEPARATION OF SOLID MATERIALS FROM SOLID MATERIALS OR FLUIDS; SEPARATION BY HIGH-VOLTAGE ELECTRIC FIELDS (separating isotopes B01D 59/00; crushing or disintegrating B02C; centrifuges or vortex apparatus for carrying out physical processes B04) [5]


B 03 DFLOTATION; DIFFERENTIAL SEDIMENTATION (sedimentation in general B01D 21/00; in combination with other separation of solids B03B; sink-float separation B03B 5/28; detergents, soaps C11D)

00Flotation (conditioning for flotation, general arrangement of plant B03B)

Notes

(1)In groups B03D 1/001 to B03D 1/018, in the absence of an indication to the contrary, classification is made in the last appropriate place.  [5]

(2)In groups B03D 1/001 to B03D 1/018, it is desirable to add the appropriate indexing code(s) from each of groups B03D 101:00 and B03D 103:00. The indexing codes should be unlinked.  [5]
