| titleOfInvention | Selective flocculation flotation method for micro-fine particle hematite |
| abstract | The invention discloses a selective flocculation flotation method for micro-fine particle hematite, and belongs to the field of hematite mineral processing. The invention is carried out according to the following steps: s1, grinding the hematite into ore pulp, enabling the ore pulp to flow into a stirring tank, adding a hematite flocculating agent and stirring; s2, adding a gangue flocculant, a collecting agent and a foaming agent for size mixing, and enabling the pulp after size mixing to flow into a flotation machine for hematite reverse flotation to obtain hematite rough concentrate; s3, continuously adding a collecting agent and a foaming agent to be used for scavenging the rougher tailings in a flotation machine to obtain hematite scavenged middlings and tailings; s4, carrying out concentration on the hematite rough concentrate to obtain hematite concentrate and concentrated middlings. The invention overcomes the defects of lower grade and lower recovery rate of hematite flotation concentrate in the prior art, can ensure effective separation of target minerals while reducing desliming operation, and relieves the problems of low grade and low recovery rate of hematite flotation concentrate. |
