Problems solved by technology

[0007] The lead-antimony coarse concentrate has a high carbon content of 8.45%. Carbon is very easy to adsorb chemicals and cover the mineral surface to hinder the action of minerals and chemicals, resulting in large consumption of chemicals and low recovery rate and grade of lead and antimony.
[0008] (3) The process fails to achieve effective separation of ore and mud
[0009] Due to the influence of the main process and equipment factors, the brittle antimony lead ore has serious sliming, and the -10μm particle size exceeds 40%, so it is impossible to remove the slime through conventional gravity separation and desliming measures
In flotation, the finer the particle size, the smaller the difference in buoyancy between the ore and the gangue, and the ore mud gangue is easy to absorb chemicals due to its large specific surface area and is easy to cover the mineral surface to hinder the action of minerals and c

Embodiment 1

[0041] Such as figure 1As shown, a kind of flotation method of fine-grained and complex brittle pyrostibite includes carbon-lead separation, lead slime separation, and lead-sulfur separation; it is characterized in that: the recovery process of the method includes the following steps:

[0042] (1) Add 2# oil to the carbon-lead separation roughing tank to carry out carbon-lead separation and roughing for the raw ore liquid, and then the ore liquid flows out in two ways, and the ore liquid with high carbon concentrate content flows into the carbon-lead separation and concentration pool, and the other All the way, the ore liquid with high lead ore content flows into the lead slime separation rougher;

[0043] (2) Sodium carbonate and collectors are added to the lead slime separation roughing tank to conduct lead slime separation and roughing for the ore liquid with high lead ore content, and then the ore liquid flows out in two ways, and the ore liquid with high lead and sulfur c...

Embodiment 2

[0054] The difference between this embodiment and Example 1 is: the addition of 2# oil in the step (1) is 13g / t; the addition of sodium carbonate in the step (2) is 40g / t, and the amount of collector The addition amount is 70g / t; the addition amount of the pH regulator in the step (3) is 450g / t, the addition amount of the zinc inhibitor is 300g / t, and the addition amount of the collector is 50g / t; The amount of collector added to the separation and scavenging pool is 15g / t; in the step (4), the amount of collector added to the first-stage purification pool is 40g / t, and zinc is added to the first-stage scavenging pool The amount of inhibitor is 40g / t, and the amount of collector added in the primary sweep pool is 15g / t; the amount of zinc inhibitor added in the secondary sweep pool in the step (5) is 40g / t t, the amount of collector added in the secondary sweep pool is 15g / t.

Embodiment 3

[0056] The difference between this embodiment and Example 1 is: the addition of 2# oil in the step (1) is 18g / t; the addition of sodium carbonate in the step (2) is 60g / t, and the amount of collector The addition amount is 90g / t; the addition amount of the pH regulator in the step (3) is 550g / t, the addition amount of the zinc inhibitor is 400g / t, and the addition amount of the collector is 70g / t; The amount of collector added to the separation and scavenging pool is 25g / t; in the step (4), the amount of collector added to the first-stage purification pool is 60g / t, and zinc is added to the first-stage scavenging pool The amount of inhibitor is 60g / t, and the amount of collector added in the primary sweep pool is 25g / t; the amount of zinc inhibitor added in the secondary sweep pool in the step (5) is 60g / t t, the amount of collector added to the secondary sweep pool is 25g / t.

Abstract

The invention discloses a flotation method for micro-fine particle complicated jamesonite. The flotation method comprises the steps of carbon-lead separation, lead-mud separation, lead-sulfur separation and the like; sulfuric acid is used as a pH regulator; a mixture of sodium carbonate, zinc sulfate and sodium sulfite is used as a zinc inhibitor; a mixture of ammonium dibutyl dithiophosphate and sodium butyl xanthogenate is used as a collector. The flotation method has simple and practical technology, and a small amount of medicament is used; the production is performed under weak-acid condition, and the recovery rate and concentrate grade of the jamesonite are improved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a flotation method of lead-antimony ore. Background technique [0002] Brittle pyrotite is a special type of mineral, its main feature is that it is dispersed in zinc-sulfur and other polymetallic deposits, it is brittle and muddy, and it is closely symbiotic with carbon in the minerals, and the lead-antimony coarse concentrate The particle size is extremely fine, so it is extremely difficult to separate the minerals by gravity separation, and it is also impossible to remove the fine-grained gangue by grading desliming. In the normal mineral processing process, it is very easy to be lost in the overflow through the floating state, and it is difficult to recover; If it is not recycled, it will seriously interfere with the recovery of other minerals and destroy the overall beneficiation process because of its strong adsorption to chemicals. [0003] At present, the recove...
