Abstract
The present invention discloses an application of trichloroisocyanuric acid as novel ore dressing inhibitor. The use level of the trichloroisocyanuric acid is from 200 to 400 g/t measured by parts by weight. The trichloroisocyanuric acid is mainly used for sterilizing and bleaching. The application of the trichloroisocyanuric acid as the inhibitor of arsenopyrite and sulfur iron ores in an ore dressing process belongs to the first time. The trichloroisocyanuric acid has obvious effect on the separation of antimonite and the arsenopyrite, and the antimonite and the sulfur iron ores as the novel ore dressing inhibitor. The trichloroisocyanuric acid has strong inhibiting effect on the arsenopyrite and the sulfur iron ores and has no harmful influence on the antimonite. The trichloroisocyanuric acid has good selectivity and is effective inhibitor for the arsenopyrite and the sulfur iron ores.
Description
Technical field
The present invention relates to the new purposes of sym-closene, especially in the mining and metallurgy field sym-closene as a kind of application of novel beneficiation inhibitor.
Background technology
Sym-closene is called for short TCCA, molecular formula C
3N
3O
3CI
3, molecular weight 232.44 claims strong chlorine oil again.Its product is a white powder, or granular, sheet, formulation such as bar-shaped, has hypochlorous pungent odour, when being heated or contacting with low amounts of water, can decompose.Sym-closene is a strong oxidizer, contacts with inflammable organic matter, acid, alkali, ammoniation kickback can take place.
Sym-closene is efficient, the organochlorine disinfectant of wide spectrum, bleaching agent, can kill various bacteriums, algae, fungi and virus.Because its hydrolysis end product is ammonia, water and carbon dioxide, no insoluble matter is considered to desirable sanitizer.Be mainly used in civilian disinfecting, swimming-pool water is disinfected, and herding, culture fishery diseases prevention, cures the disease industry and cooling circulation cooling water of air conditioner sterilization, except that algae, fruit, fresh-keeping of vegetables are handled wastewater treatment, Seed Treatment, fabric bleaching, wool shrinkproof is handled, organic synthesis industry etc.
All in the card crop type gold mine in area, it is gold that the valency that mainly contains reclaims metal in Guizhou three, gold with submicron-sized particulate-2 μ m embedding cloth in mispickel and troilite, and the carrier mineral mispickel of gold and troilite with the fines embedding cloth of-43 μ m in country rock.Less important valuable metal is an antimony, and its content is in 0.5%～1.0% range.Antimony mineral is stibnite and occurs.Require before selecting gold, must select in priority floating the antimony concentrate of qualified grade technically, and reduce antimony concentrate as far as possible and carry the gold loss secretly.Owing to there is the floatability of small part mispickel and troilite close with stibnite, even by 3～4 selected operations of antimony, the golden loss late that antimony concentrate is carried secretly is still up to 2.5～3.5%, and antimony concentrate contains antimony＜46%.Once adopted multiple routines such as potassium permanganate, clorox and bleaching powder to separate medicament, effect is very undesirable, and product contains seriously mutually in foam and the groove.
Summary of the invention
The present invention proposes the application of sym-closene as a kind of novel beneficiation inhibitor, sym-closene is mainly used in disinfection and bleaching, application as mispickel and troilite inhibitor in ore-dressing technique still belongs to the first time, as a kind of novel beneficiation inhibitor, sym-closene is to there being stibnite and separating of mispickel, stibnite and troilite remarkable result, showing as has stronger inhibitory action to mispickel and troilite, and stibnite is had no adverse effects, selectivity is good, is mispickel and troilite effective inhibitors.
After the present invention adopts sym-closene as beneficiation inhibitor, when consumption is 200～400g/t, make antimony concentrate contain antimony＞53%, antimony recovery is 85～90%, antimony concentrate band gold loss late only has 0.8～1.0%, thereby make gold recovery improve 1.5～2.7 percentage points, meanwhile, simplified technological process.
Sym-closene is except that the FLOTATION SEPARATION that is used for stibnite and mispickel, stibnite and troilite, be applicable to that also other need remove the floatation process of sulphur, arsenic, as separating technologies such as copper-sulphur, copper-arsenic, zinc-sulphur, zinc-arsenic, raising antimony, copper, zinc concentrate grade there is remarkable result.
The addition manner of sym-closene in ore-dressing technique is that to be mixed with concentration at normal temperatures be that 2%～10% the aqueous solution adds in the flotation pulp.Because the solubility of sym-closene in the time of 25 ℃ only is 1.2 grams/100 gram water, and is easily molten for making it, adds sodium carbonate or other inorganic base and be prepared into the instant effervescent formulation of energy.Pure sym-closene and corresponding effervescent formulation thereof all have a lot of manufacturer production to sell at home.In embodiments of the present invention, 5% the aqueous solution that had been mixed with after both having added pure sym-closene (accounting for 50～80%) and sodium carbonate (20～50%) mixing mutually, 5% the aqueous solution that has used also that the effervescent formulation that contains sym-closene about 50% is mixed with, its effect unanimity.How many additions all restrains sym-closene with raw ore adding per ton is represented.
