during nearly continuous operation for eight hours per
day over a 10-day period at steady-state. The calculated Fe
recovery for the plant was 63.7%, based on data gathered
from this period of steady-state operation.
During Phase III, the pilot plant was modified to
increase the feed throughput to 30 tons per hour with
essentially no loss in recovery on the primary magnet. The
maximum plant throughput was investigated by batch pro-
cessing. A throughput of 30 tons per hour was achieved.
The concentrate weight recovery was 7.3% as an average
of nine separate batch tests, which was similar to the 7.5%
determined in Campaign II. The reason the plant was ini-
tially underfed was because wet magnetic separator param-
eters were initially applied to dry processing. This indicates
that the magnets were able to recover the magnetic particles
in the dry feed than in a slurry. This phenomenon may be
worth further study.
