説明

Separation of sericite from quartz by flotation was indvestigated using dodecylammonuim acetate (DAA) as a collector. Obtained results are summarized as follows.<BR>1) Sericite floats in acidic solution, however, a great amount of DAA is required for the flotation of sericite.<BR>2) In acidic solution (pH=2.5), sericite can separate selectively from quartz. The addition of Al³⁺ decreases the amout of DAA required for the flotation of sericite.<BR>3) In alkaline solution (pH=10.5), selective separation of sericite from quartz is not so good as might be expected from the results obtained from the flotation tests of quartz and sericite. When Al³⁺is added, however, quartz is depressed and sericite floats selectively.
