Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to a kind of rich magnesium silicate mineral floating inhibitor and its preparation side
Method and application.
Background technology
China's nickel ores resource predominantly low-grade copper nickel sulfide ore rich in MgO silicate gangue minerals, such as serpentine,
Talcum, chlorite, tremolite etc., these rich magnesium silicate mineral are in floatation process, and not only argillization is serious, and itself or
" heterocoagulation " floatability is fabulous afterwards, so that severe jamming flotation, and bring difficulty to follow-up concentrate.
For a long time, magnesium problem drops around cu-ni sulphide ore flotation concentrate, both at home and abroad relevant colleges and universities, scientific research institutions, and
The engineers and technicians of industrial enterprise have done substantial amounts of research work, also have developed sodium carboxymethylcellulose (CMC), water glass
The depressing agent of a variety of rich magnesium silicate mineral such as glass, calgon, sodium humate, tannic acid, tannin extract, but put into practice table
Bright, the effect of these inhibitor is unsatisfactory.
The content of the invention
In view of the shortcomings of the prior art, an object of the present invention is that providing a kind of rich magnesium silicate mineral floating suppresses
Agent, the inhibitor is not only nontoxic, wide material sources, and can be in the case where not producing inhibitory action to sulphide ore effectively
Suppress gangue mineral, so that on the premise of the flotation concentrate rate of recovery is not influenceed, MgO content, the suppression effectively in reduction concentrate
Preparation by weight, including：
2~30 parts of mannosan；
5~25 parts of sodium gluconate；

5~15 parts of sodium tripolyphosphate；
The mannosan is one kind in konjak glucomannan, aloe mannosan.
It is preferred that, when the copper nickel sulfide mineral for handling strong alteration（That is the further alteration of serpentine is into talcum）When, the suppression
Agent by weight, including：
10~30 parts of mannosan；
5~20 parts of sodium gluconate；
5~10 parts of sodium tripolyphosphate；
The mannosan is one kind in konjak glucomannan, aloe mannosan.
It is preferred that, the inhibitor by weight, is made up of following component：5 parts of aloe mannosan, sodium gluconate
15 parts, 10 parts of sodium tripolyphosphate.
It is preferred that, the inhibitor by weight, is made up of following component：5 parts of konjak glucomannan, glucose
Sour 15 parts of sodium, 5 parts of sodium tripolyphosphate.
It is preferred that, the inhibitor by weight, is made up of following component：25 parts of konjak glucomannan, glucose
Sour 10 parts of sodium, 5 parts of sodium tripolyphosphate.
Another object of the present invention is the method that offer prepares above-mentioned inhibitor, and this method comprises the following steps：
1）By weight, 2~30 parts of mannosan, 5~25 parts of sodium gluconate, 5~15 parts of sodium tripolyphosphate are prepared,
And mix；The mannosan is one kind in konjak glucomannan, aloe mannosan；
2）Weigh step 1）The water of 50~100 times of raw material gross weight part, is heated to more than 80 DEG C, then by step 1）Raw material
Slow uniform addition, is stirred continuously, it is fully dissolved simultaneously.
Another object of the present invention is to provide application of the inhibitor on rich magnesium silicate mineral floating, its
It is characterised by, the consumption of the inhibitor is 300-400 g/t.
Beneficial effects of the present invention：
1st, not only raw material sources are wide, cheap and low-consuming for inhibitor of the present invention（Only conventional dose consumption
50%）, prepare it is simple, beneficial to commercial Application；
2nd, inhibitor of the present invention has good selective effect, while rich magnesium silicate mineral are suppressed, Bu Huiying
Ring the flotation of valuable mineral；
3rd, floatation indicators of the invention are high, and concentrate content of MgO is not higher than 6%.
