Reverse flotation separation of hematite from quartz

1/8/2019· The effect of magnetite as a magnetic seed on the flotation separation of fine hematite and quartz was studied by reverse micro-flotation and sedimentation The results demonstrate that fine magnetite could selectively report to the pulp product with hematite particles, forming aggregates that avoided attachment to quartz particle surfac.
