Abstract
A method for floating scheelite, a method for floating scheelite with higher fluorite content. The method is characterized in that in the beneficiation process, alkyl amide sodium (potassium) sulfosuccinate is used as a collecting agent. The method for floating scheelite has the characteristic of high selectivity to the scheelite minerals, can obtain qualified rough concentrate only by once rough concentration, and overcomes the defects of poor selectivity, large medicament dosage and serious pollution of the conventional method using the fatty acid collecting agent. Provides an effective method for scheelite mineral flotation.
Description
Technical field
A kind of method of flotation scheelite, especially a kind of method for floating that contains the higher scheelite of fluorite.
Background technology
In existing mining processing industry technology, the flotation of scheelite mineral generally adopts aliphatic acid (as oxidized paraffin wax soap) to make collecting agent under strong alkaline condition, makes inhibitor with waterglass and suppresses gangue mineral.General slurry pH is more than 10, and the consumption of waterglass is more than 1000g/t.
The shortcoming of above-mentioned prior art is:
The poor selectivity of aliphatic acid (as oxidized paraffin wax soap), when especially fluorite content is high in the ore pulp, in most cases the concentration ratio of scheelite has only 2～3, when the content of scheelite hangs down, brought great inconvenience so just for follow-up ore dressing, not only influence the recovery index of scheelite, also influence the recovery of other mineral.Simultaneously, the consumption of medicament greatly also pollutes to environment.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and a kind of selectivity height is provided, and can effectively reduce dosing, reduces the method for the flotation scheelite that pollutes.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of flotation scheelite is characterized in that its ore dressing process adopts alkylamide sulfosuccinate sodium (potassium) as collecting agent.
The method of a kind of flotation scheelite of the present invention, the alkyl that it is characterized in that described collecting agent alkylamide sulfosuccinate sodium (potassium) are the group of carbon 12-carbon 18.
The method of a kind of flotation scheelite of the present invention, the slurry temperature that it is characterized in that ore dressing process is 25-50 ℃.
The method of a kind of flotation scheelite of the present invention, adjusting slurry pH when the scheelite that it is characterized in that ore dressing process is roughly selected is 9-11.
The method of a kind of flotation scheelite of the present invention is characterized in that the section of roughly selecting of the scheelite of ore dressing process is carried out once or recleaning, and once or secondary scan.
The method of a kind of flotation scheelite of the present invention is characterized in that adding waterglass in the once described or recleaning of ore dressing process; During scanning, once described or secondary adds described employing alkylamide sulfosuccinate sodium (potassium) collecting agent.
The method of a kind of flotation scheelite of the present invention is characterized in that the waterglass consumption that the described scheelite of the ore dressing process section of roughly selecting is roughly selected with selected adding is 200-2000g/t, and the consumption of the collecting agent that adds in roughly selecting and scanning is 100-1000g/t.
The method for floating of a kind of scheelite of the present invention uses alkylamide sulfosuccinate sodium (potassium) to make collecting agent.When the flotation of scheelite, the temperature of scheelite ore pulp is adjusted to 25-50 ℃, in the scheelite grade is the ore pulp of 0.3-0.4%, add pH respectively successively and adjust agent, waterglass, collecting agent and stir, can obtain to contain WO through one roughing
32%-5%, the scheelite rough concentrate of rate of recovery 70%-79%.The method of this flotation scheelite has the characteristics to scheelite mineral high selectivity, can only just can obtain qualified rough concentrate by one roughing, has overcome conventional use 733 collecting agent method poor selectivity, big, the with serious pollution shortcoming of dosing.For the scheelite mineral floating provides a kind of effective ways.

Fig. 1 is the process chart of the inventive method.
The specific embodiment
A kind of method of flotation scheelite, its ore dressing process adopt alkylamide sulfosuccinate sodium (potassium) as collecting agent; The chemical constituent of collecting agent is an alkylamide sulfosuccinate sodium (potassium).Collecting agent is generally paste, also can be powdery, in the water soluble.
Specifically comprising step is:
At first, raw ore is carried out sulfide flotation, flotation tailing carries out wolframite and sorts, and the mine tailing that sorts behind the wolframite carries out sorting of scheelite.With selecting the ore pulp of scheelite to add concentration basin, regulate slurry pH to desired value, add waterglass then, add collecting agent at last, and stir flotation, obtain the scheelite rough concentrate.
In the rougher process, slurry pH conditioning agent and waterglass can successively separate adding, also can add together, and mixing time is about 2-3 minute, adds described collecting agent then, and mixing time is about 3 minutes.Then described tungsten rough concentrate is carried out the selected tungsten rough concentrate that obtains than high-grade 1-2 time, described mine tailing is carried out scanning for 1-2 time.
Described tungsten is selected to be 1-2 time, and it is selected or secondary tungsten is selected to be respectively tungsten, and the chats in the refining process returns in the last beneficiation steps each time.Concrete selected number of times can be selected as the case may be.It is selected or add described waterglass and carry out selected to carry out blank during a described tungsten is selected.
Described tungsten is scanned and is 1-2 time, is respectively that tungsten is scanned or secondary tungsten is scanned, and the chats of scanning each time in the process returns in the last beneficiation steps.Concrete tungsten is scanned number of times and can be selected as the case may be.Can add collecting agent during tungsten is scanned, tungsten is scanned the mine tailing that is that is left in the pit.
Scheelite Flotation of the present invention is will add the scheelite ore pulp successively by the order of pH value conditioning agent, waterglass, collecting agent respectively, and stirs, and is selected through one roughing, 1-2 time, scan for 1-2 time and can obtain to contain WO
33-7%, the tungsten rough concentrate of the rate of recovery more than 75%.
