Description
One, technical field
The present invention relates to a kind of preparation method of realgar mineral inhibitor, which is suitable for the bulk concentrate flotation of antimony arsenic
Separation, obtains low arsenic antimony concentrate.
Two, background technique
In the floatation process of stibnite, since the floatability of stibnite is preferable in acid condition, therefore stibnite is floating
Choosing generally carries out in acid condition；But when containing a large amount of arsenic-containing ores in stibnite, when especially containing a large amount of realgar mineral,
A large amount of realgar mineral also enter in stibnite concentrate while flotation stibnite, the flotation point for stibnite and realgar mineral
From ore dressing worker has done a large amount of work, but the relevant report being really applied is less.It is general to use in smelting process
The separation of antimony arsenic is carried out, but environmental protection pressure is big, it is high to smelt separation costs, as can realizing the separation of antimony arsenic using selective depressant, no
Only enterprise brings economic benefit, while having the meaning of reality to the separation of antimony arsenic.
Three, summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of realgar mineral inhibitor, and the inhibitor being prepared can
There is good inhibiting effect to realgar mineral, inhibiting effect is not generated to the antimony in antimony arsenic bulk concentrate, it is comprehensive to improve mineral resources
It closes and utilizes.
The present invention reaches above-mentioned purpose using following technical scheme：A kind of preparation method of realgar mineral inhibitor, including
Following steps：
(1) 20~25g is added to 100~120ml volumetric concentration to nigrosine is in 20% metabisulfite solution, and heating makes
It is dissolved, and is cooled to 25 DEG C, and being slowly added to 35~40ml mass percentage concentration at this temperature is that 20% sodium sulfide solution obtains
Product 1；
It (2) is that 1.5mol/L sodium hydroxide is configured to solution and cooling by 25~30g tapioca and 25~30ml concentration
To 15 DEG C, it is coupled under the conditions of pH11~11.5 with product 1 and obtains product 2, product 2 and meta-xylene in pH11~11.5
The powder for being coupled soluble easily in water under part is the inhibitor；
It is that the inhibition is added in 700~800g/t by the total dosage of medicament in floatation process when flotation under the conditions of natural pH
Then agent adds diethyldithiocarbamate 50g/t and makees antimony mineral collecting agent, 2# oil 30g/t makees foaming agent and carries out collecting to antimony mineral.
In use, the inhibitor is first configured to the aqueous solution that mass percentage concentration is 3~5%.
Unless otherwise stated, percentage of the present invention is mass percent, and the sum of each component content percentage is
100%.
Particularly advantage of the invention is：
1, there can be good inhibiting effect to realgar mineral using inhibitor prepared by the present invention, to antimony arsenic bulk concentrate
In antimony do not generate inhibiting effect, improve mineral resources comprehensive utilization.
2, dosing is few, nontoxic and pollution-free.
