| 摘要 |
The invention concerns, in one aspect, a ferrohydrostatic separation method in which a ferrofluid is used to separate materials of different density. In th e method, the apparent density of the ferrofluid is controlled by means of a vertically orientated magnetic field generated by a C-dipole, open dipole (O - dipole) or split pair electromagnet or permanent magnet. Other aspects of th e invention include an apparatus for use in this method and a process for separating materials of different density using the method.
