Description
One, technical field
The present invention relates to the preparation technical field of beneficiation reagent, the preparation method of specifically a kind of mispickel inhibitor.
Two, background technique
Sulfoarsenic mineral FLOTATION SEPARATION is mainly the FLOTATION SEPARATION of pyrite and mispickel, due to mispickel and pyrite
Floatability it is extremely close, cause in the production of sulphide ore mining processing industry, arsenic would generally be with sulphide ore association, therefore sulphur difficult to realize
Arsenic separation, the content of arsenic directly affect the quality of iron concentrate, iron concentrate drop arsenic be select factory necessarily arrange act.Some sulphur arsenic separation
Factory is selected, arsenic content is generally 1% or so in flotation of sulfur concentrate, and therefore, the flotation of pyrite and mispickel efficiently separates not
It is only capable of improving the economic benefit in dressing plant, and there are also have certain theory and practice meaning.
Three, summary of the invention
The purpose of the present invention is to provide a kind of preparation method of arsenic yellow iron inhibitor, the inhibitor being prepared into can inhibit
Mispickel does not generate inhibiting effect to pyrite, and sulphur arsenic bulk concentrate is made to be easily isolated to obtain sulphur, arsenic concentrate.
The present invention reaches above-mentioned purpose using following technical scheme：A kind of preparation method of mispickel inhibitor, including
