Reverse flotation separation of hematite from

2019-8-1  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 surfaces.

Reverse flotation separation of hematite from

2019-8-1  Abstract. In this work, fine magnetite was used as a magnetic seed to enhance the separation efficiency of fine hematite from quartz during reverse micro-flotation. Gradual increases in hematite recovery and iron grade were accomplished with increasing magnetite content, whereas the iron content in quartz reject decreased.

Magnetite an overview ScienceDirect Topics

Magnetite. Magnetite is the main iron mineral recovered using crushing and grinding, followed by magnetic separation and in some instances flotation to produce a magnetite concentrate. From: Iron Ore, 2015. Related terms: Nanoparticles; Iron Oxide Nanoparticle; Oxide; Ion; Adsorption; pH Value; Magnetic

Flotation Cell an overview ScienceDirect Topics

Imhof et al. (2005) detailed the use of pneumatic flotation cells to treat a magnetic separation stream of a magnetite ore by reverse flotation to reduce the silica content of the concentrate to below 1.5%. From laboratory testing, they claimed that the pneumatic cells performed better than either conventional mechanical cells or column cells.
