ABSTRACT:
A process for the continuous production of cobalt-modified magnetic iron oxide. This process comprises carrying out a batchwise preliminary cobalt treatment by adding a magnetic iron oxide powder to an alkaline solution followed by the addition of a cobalt salt to cover the magnetic iron oxide powder with cobalt. A cobalt modification reaction is carried out continuously by passing the solution containing the preliminary cobalt-treated magnetic iron oxide powder under heat and pressure through a flow-type reaction vessel.
