Title: Beneficiation method
Inventor: HIROYOSHI NAOKI
IPC: B03D1/012
Filed: 2020-02-18
Abstract: To provide a beneficiation method enabling fine powder of copper ore to be efficiently coagulated.SOLUTION: The beneficiation method comprises a coagulation step of coagulating fine particles of copper ore, by adding emulsification kerosene into an ore slurry including fine particles of copper ore having a particle size D50 of 5 μm or smaller, and an ore flotation step of performing ore flotation using the ore slurry after the coagulation step. A large part of the kerosene acts on the copper ore since the emulsified kerosene is difficult to separate into a water phase and an oil phase. In addition, kerosene included in the emulsified kerosene has an oil droplet of the same size as that of fine particles of copper mineral, so that the kerosene included in the emulsified kerosene is easy to adhere to the copper ore. Therefore, fine particles of the copper mineral can be efficiently coagulated by adding the emulsified kerosene to the ore slurry.SELECTED DRAWING: Figure 4
