Description
One, technical field
The present invention relates to a kind of preparation method of troilite thing inhibitor, be applicable to that the plumbous sulfur mineral that contains gold or silver in the vulcanized lead mineral separates, and obtains to contain gold or silver lead ore concentrate.
Two, background technology
In plumbous sulfur mineral FLOTATION SEPARATION process, the general employing adds a large amount of lime to press down sulphur as the inhibitor of troilite thing floating plumbous, thus make plumbous sulphur content from, obtain lead concentrate; But when containing gold or silver in the lead minerals, can not make troilite thing inhibitor with lime, this is because in floatation process, lime is to containing gold or the silver mineral inhibitory action is apparent in view, gold or silver are suppressed inevitably, lose in mine tailing, so not only make resource fail to obtain fully comprehensive the recovery, also reduced the income of enterprise.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of troilite thing inhibitor, the troilite thing inhibitor that is prepared into this method can suppress the troilite thing, and gold in the lead minerals or silver are not produced inhibitory action, and gold or silver are enriched in the lead concentrate.
The present invention achieves the above object by the following technical solutions: a kind of preparation method of troilite thing inhibitor, comprise the steps: that it is in 20% sulfuric acid solution that 14～16g paranitroanilinum is joined 120～150ml volumetric concentration, heating makes its dissolving, in ice bath, be cooled to 10 ℃ again, under this temperature, slowly add 25～30ml mass percentage concentration and be 25% sodium nitrite solution and obtain product 1, with 12～15g 4,4 '-diaminobenzene sulfonanilide and 15～20ml1mol/L hydrochloric acid is mixed with solution and is cooled to 10 ℃ in ice bath, obtain product 2 with product 1 coupling under pH9～10 conditions, coupling under pH10～11 conditions gets black powder soluble in water and is described troilite thing inhibitor product 2 and 15～20ml1mol/L m-phenylene diamine (MPD).
The application of described troilite thing inhibitor in plumbous sulphur associated mineral FLOTATION SEPARATION, after earlier ore ore grinding to mineral monomer being dissociated, transferring slurry pH with sodium carbonate is 8～9, in the floatation process, add described troilite thing inhibitor by 250～350g/t, and then add 100～150g/t diethyldithiocarbamate as plumbous collecting agent and 80～100g/t2 oil as foaming agent.
During use, earlier described troilite thing inhibitor is mixed with mass percentage concentration and is 1～2% the aqueous solution.
Concrete advantage of the present invention is:
Described troilite thing inhibitor has the good restraining effect to the troilite thing, and gold in the lead minerals or silver mineral are not produced inhibitory action, and dosing is few, nontoxic pollution-free.
