Abstract

Continuous bauxite extraction appts. in which the bauxite (I) with an NaAlO2 wash (II) is treated in a tube (III) pressurised at 10-200 atm. and at 150-300 degrees C. A suspension of (I) in (II) is passed through (III) by a membrane and piston high pressure pump, (III) acts as preheater with one tube through which vapour from (II) pressure reducers are passed. Heat exchangers are heated by biphenyl vapours with an organic liquid themal vehicle with a molten saline mass. Partic. a complementary collector in which the almost completely reacted mixture is further pressure treated, is provided downstream of (III).
