Conversely, the apatite and gangue minerals in the nonmag-
netic products showed no magnetite coating(Figure 7b).
This finding further confirms the feasibility and reliability
of the wet pre concentration technology.
A comparative test of phosphorus recovery by single
stage flotation and magnetic separation with flotation com-
bined was conducted. The flowchart is shown in Figure 8,
and the test results are shown in Table 6.The results showed
