Extraction of materials (A) from silane-modified oxide or silicate fillers (I) involves using a gas condensed using pressure and/or temperature as extractant (II), where (II) is passed in a radial direction through (I) in a pressure vessel and/or (A) extracted from (I) is removed from (II) using a sorbent (III). An independent claim is included for apparatus for carrying out the process, comprising at least one pressure vessel, having at least one gas-permeable internal container, screen or insert to receive (I), at least one gas inlet and outlet located in a fluidized bed of (I) and a radially placed gas inlet and outlet from the fluidized bed (specifically such that gas can flow radially inwards from the outside or radially outwards from the inside). |
