Abstract
The invention discloses a kind of beneficiation methods containing two types copper cobalt sulfide ore containing cobalt mineralss, include: to sequentially add copper cobalt activator, selective copper cobalt collecting agent progress copper cobalt roughing and copper cobalt into crude ore pulp to scan, obtains copper cobalt rough concentrate and copper cobalt scans Tailings Slurry；PH regulator, gangue mineral inhibitor are added into copper cobalt rough concentrate, and it is selected to carry out copper cobalt, obtains copper cobalt concentrate；Chats is carried out after the selected underflow of first time copper cobalt is merged with the foam that first time copper cobalt is scanned to select again；To copper cobalt scan Tailings Slurry select again with chats-merging for the underflow scanned of essence be added that cobalt activator, cobalt collecting agent, xanthate collectors and foaming agent carry out cobalt roughing and cobalt is scanned in ore pulp, obtain cobalt rough concentrate；The progress of cobalt rough concentrate is selected, obtain cobalt concentrate.The present invention not only can effectively solve the problem of lower copper cobalt bulk concentrate quality, influence concentrate quality, improve copper cobalt bulk concentrate product quality, and ensure that effective recycling to copper, cobalt, improve flotation concentrate value.
Description
Technical field
The present invention relates to copper cobalt ore technical field of beneficiation, more particularly to a kind of copper cobalt sulfide ore containing cobalt mineralss containing two types
Beneficiation method.
Background technique
Copper, cobalt are the important metal resources of human social development.According to the difference of ore properties, wet process smelting is mainly used
Copper and cobalt resources in the methods of golden (leaching), gravity treatment, flotation, magnetic separation recycling ore.According to the difference of ore oxidation rate, can be divided into
Copper cobalt sulfide ore (copper, cobalt oxide rate < 10%), mixed copper cobalt ore (copper, cobalt oxide rate < 10%~30%) and cobalt copper oxide
(copper, cobalt oxide rate > 30%).The method that wherein copper cobalt sulfide ore, mixed copper cobalt ore mainly use flotation is recycled.
Copper-bearing mineral mainly has chalcopyrite, vitreous copper, bornite, covellite, bluish grey copper mine, native copper, peacock in nature
Stone etc.；Mainly there are carrollite, cabalt glance, cobalt pyrite, cobaltite, heterogenite etc. containing cobalt mineralss.Cobalt according to existence form not
Together, and it is divided into and independent is present in (such as pyrite in a certain mineral containing cobalt mineralss (such as carrollite), in isomorph or inclusion enclave
Containing cobalt), in adsorption form be present in certain mineral surfaces three types.
By taking copper cobalt sulfide ore as an example, according to the difference of cupric, cobalt mineralss in ore dressing process, it is floating that the mixing of copper cobalt is respectively adopted
Choosing, successively the techniques such as diffeential floatation are recycled copper cobalt.And for copper, cobalt element, (such as copper-bearing mineral is not in identical mineral
Chalcopyrite, vitreous copper etc. are pyrite etc. containing cobalt mineralss, i.e., copper, cobalt element be not in identical mineral) ore, the mixing of copper cobalt
Flotation can carry out separation of Cu and Co according to the different of cupric cobalt mineralss in ore again, obtain copper concentrate, cobalt concentrate respectively.For ore
In containing two types containing cobalt mineralss (have simultaneously i.e. in ore independent containing cobalt mineralss and Pyrite cobalt-containing) when, existing ore dressing skill
Art uses copper cobalt bulk flotation technique to be handled substantially, without separation of Cu and Co operation.
To containing two types containing cobalt mineralss copper cobalt sulfide ore carry out the bulk flotation of copper cobalt have the following problems: (1) due to
Type-Inconsistencies containing cobalt mineralss carry out separation of Cu and Co by force and obtain single copper concentrate, cobalt concentrate, it is mutual to will cause copper, cobalt concentrate
Containing serious, work-in-process costing is influenced；(2) since Pyrite cobalt-containing enters final copper cobalt bulk concentrate, this will cause concentrate copper, cobalt product
Position reduces simultaneously, influences product quality, and then influence work-in-process costing coefficient.If unilaterally guaranteeing copper cobalt concentrate quality, reduce
Pyrite cobalt-containing enters final copper cobalt concentrate, then will affect the rate of recovery of cobalt.
In terms of beneficiation reagent, traditional copper cobalt mineralss collecting agent usually emphasizes that copper cobalt mineralss mix strength collecting, improves
Copper cobalt comprehensive recovery, rare use copper cobalt selective copper collector are especially rare to use selective collecting copper-bearing mineral, cupric
The medicament of cobalt mineralss (copper cobalt ore element is in same mineral) and Pyrite cobalt-containing.Meanwhile in the actual production process, containing above-mentioned
Two types often contain containing the copper cobalt sulfide ore of cobalt mineralss (having simultaneously independently i.e. in ore containing cobalt mineralss and Pyrite cobalt-containing)
Carbonate gangue is more, activates containing sulfur minerals, acid consumption higher cost using sulfuric acid process, and be difficult to obtain preferable floatation indicators；It adopts
When with single copper sulphate for activation, it tends to be difficult to play good activation to Pyrite cobalt-containing.
In conclusion how to be improved finally in the ore dressing process of the copper cobalt sulfide ore containing cobalt mineralss containing two types
While concentrate product quality, guarantees effective recycling of copper, cobalt, become technical problem urgently to be resolved.
Summary of the invention
