Embodiment 1

[0024] The copper sulfide ore contains 0.70% copper, and the oxidation rate is 8%. The copper sulfide mineral is chalcopyrite, the copper oxide mineral is malachite, the ore type is hydrothermal type, and the fluid inclusions are rich.

[0025] (1) The ore is ground at a concentration of 80-85wt% until the dissociation degree of the copper sulfide mineral monomer is greater than 80%, the grinding fineness is -200 mesh and the content reaches 88%. The copper in the fluid inclusions of the copper sulfide mineral Ions are released into the slurry solution while the newly formed surface of the copper sulfide mineral relaxes to form a "sulfur-rich" surface.

[0026] (2) Dilute the copper sulfide ore grinding slurry obtained in step (1) with water to a concentration of 30wt%, add 60g / t ammonium chloride, put it into the first sealed mixing tank, and slow down at a speed of 0.5-1m / s Stir at high speed, so that the copper ions released from the fluid inclusions and the added copper io...

Embodiment 2

[0030] The copper sulfide ore contains 0.90% copper, and the oxidation rate is 10%. The copper sulfide mineral is mainly chalcopyrite, followed by chalcocite, the copper oxide mineral is malachite, the ore type is hydrothermal type, and the fluid inclusions are rich.

[0031] (1) The ore is ground at a concentration of 80-85wt% until the dissociation degree of the copper sulfide mineral monomer is greater than 80%, the grinding fineness is -200 mesh and the content reaches 90%. The copper in the fluid inclusions of the copper sulfide mineral Ions are released into the slurry solution while the newly formed surface of the copper sulfide mineral relaxes to form a "sulfur-rich" surface.

[0032] (2) Dilute the copper sulfide ore grinding slurry obtained in step (1) with water to a concentration of 35wt%, add 70g / t of ammonium chloride, put it into the first sealed mixing tank, and slow down at a speed of 0.5-1m / s Stir at high speed, so that the copper ions released from the fluid...

Embodiment 3

[0036] Copper sulfide ore contains 1.10% copper grade and 12% oxidation rate. The copper sulfide mineral is mainly chalcopyrite, followed by bornite. The copper oxide mineral is malachite. The ore type is hydrothermal metamorphic type with fluid inclusions , but less than the hydrothermal type.

[0037] (1) The ore is ground at a concentration of 80-85wt% until the dissociation degree of the copper sulfide mineral monomer is greater than 80%, the grinding fineness is -200 mesh and the content reaches 85%. The copper in the fluid inclusions of the copper sulfide mineral Ions are released into the slurry solution while the newly formed surface of the copper sulfide mineral relaxes to form a "sulfur-rich" surface.

[0038] (2) Dilute the copper sulfide ore grinding slurry obtained in step (1) with water to a concentration of 40wt%, add 5 (or 8, or 10) g / t of copper sulfate, add 100 g / t of ammonium chloride, and put it into the A sealed mixing tank is stirred at a slow speed of 0...

Abstract

The invention relates to a self-activation flotation method for a component of a fluid inclusion of a copper sulfide ore. Specific to the 'rich sulfur' state formed by surface relaxation of the copper sulfide ore, by utilizing the characteristics that copper ions released by the fluid inclusion of the copper sulfide ore have ultrahigh adsorption activity on a 'rich sulfur' surface, the copper ions of the component of the fluid inclusion are attached to a new surface of the copper sulfide ore so as to form a 'rich copper' surface, so that the adsorption activity of the surface of the copper sulfide ore to xanthate anions is increased, the self-activation flotation for the surface of the copper sulfide ore is realized, the flotation recovery of the copper sulfide ore is increased, the dosage of collecting agents is reduced and the technical and economic targets are increased.

Description

technical field [0001] The invention relates to a self-activating flotation method for fluid inclusion components of copper sulfide ore, and belongs to the technical field of mineral processing. Background technique [0002] Copper sulfide ore is the main source of copper resources, and flotation is the main method for recovering copper sulfide ore. Almost 90% of copper sulfide ore is recovered through flotation, so flotation plays an important role in the recovery and utilization of copper ore resources. status. Different copper sulfide ores use different collectors according to their mineral composition, but the most commonly used collectors for flotation of copper sulfide ores are mainly sulfhydryl collectors such as xanthate, black medicine, and esters. There are also several collectors used in combination to improve the harvesting effect. Due to the good floatability of copper sulfide ore compared with other minerals, there are relatively few studies on the proces...
