Electrodynamic Separation – a New Dry Processing Technology BATEMAN is marketing a new dry technology to separate materials more
economically than before, e.g. rutile from sand or vermiculite and quartz.
The technology applies sharply non-linear electric fields to polarise
and charge materials to differing degrees depending on their conductivities
and dielectric constants.
BATEMAN Electrodyn minerals processors offer several attractive advantages.
Their power consumption is negligible and five orders of magnitude lower
than with other electrical or electrostatic separation processes. Significantly
for this type of process, they are relatively unaffected by surface
and atmospheric conditions. The mass of the installed equipment is low,
there are few moving parts and the modular construction facilitates
installation in the space available. No specialised skills are required
to operate the equipment and operating and maintenance costs are minimal.
The BATEMAN Electrodyn Model Edge is recommended for processing vermiculite,
apatite and chromite, sulphides, phosphates, diamonds and semi-precious
stones, feldspar and calcites, the recovery of conducting mineral sands
(e.g. rutile) and carbon degritting and contaminant removal.
Although the scientific principles of electro dynamic separation were
discovered over eighty years go, it is only in recent years that an
R & D programme led by Anglo American Research laboratories as made
practical application a reality. BATEMAN has the global commercial licence
and markets the technology.
