Description
Technical field
The present invention relates to a kind of activation method of smithsonite floatation process, relate in particular to the activation method of low-grade zinc oxide ore floatation recovery smithsonite, belong to the technique of preparing field.
Background technology
China's zinc oxide ore resource reserve is abundant; Lean ore is many, and rich ore is few, and it is concentrated relatively to distribute; Mainly be distributed in provinces such as Yunnan, Guizhou, Gansu, Shaanxi; Especially reserves are bigger in Yunnan, and only Yunnan Province's zinc metal reserves are just had an appointment 7,100,000 tons, and ground such as the Qinghai and the Inner Mongol also have a certain amount of zinc oxide mineral deposit to distribute.Yet the zinc oxide ore resource of the low-grade high impurity of China is not rationally utilized owing to lack efficiently the processed technology.
The zinc oxide mineral are one type of important zinc-bearing minerals, are the results of the long-term weathering of zinc sulfide ore, and as the secondary mineral of zinc, the zinc oxide ore thing with industrial value mainly contains smithsonite, smithsonite, willemite and marionite etc.Because its mineral species is various, the association of mixing each other, and disseminated grain size is thinner; The argillization state is more serious; Often contain a certain amount of soluble-salt, iron oxide and clay sludge in this type of oxide ore simultaneously, make the ore dressing of zinc mineral reclaim very difficulty, the rate of recovery is on the low side.
Smithsonite is common in the zinc oxide ore one of zinc oxide mineral of industrial value to be arranged most; The ratio that it accounts in zinc oxide ore is only second to smithsonite; But smithsonite is because of its complicated structure, and exclusive surface nature is thought one of extremely difficult mineral that reclaim by ore dressing circle at present.For the flotation of smithsonite, sulfuration-primary amine method that people such as external Maurice Rey, Mckenna propose extensively adopts in industry, although this method affect factor is numerous, and flotation conditions is also very harsh.But the flotation of smithsonite do not obtain stride the epoch progress before, this method has still received favor widely.Because smithsonite is normal and smithsonite association coexistence; Most studies worker wants to reclaim smithsonite simultaneously with the sulfide flotation of smithsonite; Have to abandon because of the sulfuration ten minutes difficulty of smithsonite eventually, present documents and materials both domestic and external are not all seen the relevant report that this method is used.Therefore, in order to reclaim the smithsonite in the zinc oxide ore efficiently, be badly in need of proposing a kind of activating technology of new smithsonite,, improve the resource utilization of zinc oxide ore to realize the efficient flotation of smithsonite.
Summary of the invention
Because zinc oxide ore character is complicated, contained mineral species is various, for solving in the zinc oxide ore characteristics such as smithsonite is hard to manage, the invention provides a kind of activation method of smithsonite floatation process, is used to solve the activation problem of floatation process smithsonite.
Technical scheme of the present invention is: adopt hydroximic acid sodium, sodium carbonate and vulcanized sodium combination activator to replace single activator to carry out activation, its concrete steps are passed through as follows:
(1) the quality percentage composition with smithsonite minal dry grinding to the qualified grade of 320 purposes accounts for 80 ~ 90wt%, obtains testing test portion;
(2) with the test test portion of step (1) ore pulp by solid-to-liquid ratio 1:2~1:3g/L, in the slip that stirs, add activator, it adds total amount is 80~140mg/L of ore pulp volume; Be 4~5min action time, adds collecting agent 30 ~ 40 mg/L then, and collecting agent action time is 4~5min; Carry out flotation after sizing mixing and scrape bubble; It is 5 ~ 7min that the bubble time is scraped in flotation, and the froth pulp that scrapes is flotation concentrate, and all the other are mine tailing.
Said smithsonite is for containing zinc 48.70 ~ 50.00wt%, and all the other are impurity such as calcium, magnesium, aluminium, iron, silicon, titanium.
Said activator is the emulsion of hydroximic acid sodium, sodium carbonate and vulcanized sodium, wherein hydroximic acid sodium: sodium carbonate: the mole proportioning of vulcanized sodium is 1:3:3, is common commercially available.
Activator hydroximic acid sodium in the said step (2) is by hydroximic acid formed sodium salt-hydroximic acid sodium after saponification.
Collecting agent in the said step (2) is dodecyl primary amine or dodecyl primary amine salt, is common commercially available.
Compared with prior art; The present invention has following advantage and good effect: through the combination activation of activator; Its effect is superior to the activation effect of single activator, when can improving the floatation indicators of smithsonite by a relatively large margin, can also reduce the consumption of vulcanized sodium.Combination activation effect of the present invention is superior to the effect of conventional activation, and total consumption of vulcanized sodium can reduce by 20 ~ 30%; Adopt activation method of the present invention, more conventional active flotation, the rate of recovery of smithsonite can improve 6 ~ 12 percentage points.
