The invention discloses a micro-fine particle
hematite selective
flocculation flotation method, and belongs to the field of
hematite mineral processing. The micro-fine particle
hematite selective
flocculation flotation method comprises the following steps that S1, hematite is levigated to form ore pulp, the ore pulp flows into a stirring tank, and a hematite flocculating agent is firstly added tobe stirred; S2, a
gangue flocculating agent, a collector and a
foaming agent are added for pulp mixing, and the ore pulp obtained after pulp mixing flows into a flotation
machine to be subjected to hematite
reverse flotation to obtain hematite coarse concentrate; S3, a collector and a
foaming agent are continuously added to be used in the flotation
machine to conduct
scavenging on rougher
tailings, and hematite
scavenging middlings and
tailings are obtained; and S4, the hematite coarse concentrate is finely selected to obtain hematite concentrate and finely-selected medium ore. The micro-fineparticle hematite selective
flocculation flotation method overcomes the defects of low hematite flotation concentrate grade and low
recovery rate in the prior art, effective separation of objective mineral is guaranteed while desliming operation is reduced, and the problems of the low hematite flotation concentrate grade and the low
recovery are solved.
