Abstract
The invention relates to a method for preferentially floating zirconite from magnetic separation tailings of seashore placer. The method of the invention is characterized in that 1-hydroxy-alkyl-1, -1-diphosphonic acid is used as a high-selectivity collecting agent for preferentially floating zirconite, humic acid or salts thereof are used as an inhibitor of non-zirconium minerals, and the method has the advantages of wide separation pH value range, high recovery rate and concentrate quality, good separation effect, short ore pulp pretreatment time, normal temperature, simple process, convenient operation and control and the like. Repeated tests prove that the method has excellent repeatability and can be widely used for the preferential flotation of zirconite in various zirconium-containing seashore placer and zirconium-containing ores.
Description
The present invention is the flotation separation method of a kind of zircon and titaniferous and other non-zirconium ore thing.Be specifically designed to the diffeential floatation of zircon in the beach placer of titaniferous zirconium.
Beach placer is to extract titanium and zirconium ore thing most important material source, contained mineral species is more, and the metalliferous mineral that often contains has titaniferous ores such as ilmenite, rutile, white titanium ore and anatase, and zircon and monazite etc., gangue mineral is mainly quartz, and mineral granularity is thick and even.Handle at present this class ore and generally adopt gravity separation method at first to abandon light minerals such as most quartz, the bigger titanium zirconium rough concentrate of the proportion of gained after drying, magnetic separation obtains ilmenite concentrate, magnetic tailing is that non-magnetic product is the raw material that selects zirconium.Magnetic tailing is quartzy with the repeatedly selected removal of shaking table, behind its concentrate drying, adopts complicated electric separation technology repeatedly to sort repeatedly, selects titaniferous ores such as rutile, and nonconducting product is zircon ore concentrate.Because shaking table sorts Ex-all quartz fully, will sneak in the zircon concentrate during electric separation, causes concentrate quality not high.In addition because gravity treatment and electric separation joint process complexity, sorting operation are many, the process loss greatly, make the zircon rate of recovery very low, generally only about 60%.The process of existing recovery zircon is more, mainly based on weight, magnetic, floating and electric separation process integration, also has and adopts single flotation to sort the method for zircon.As the data introduction, certain company of Australia is with 0.5% soap solution that contains 0.025% caustic soda about 20 minutes of stir process magnetic tailing when 95 ℃ of temperature, uses 0.2% sulfuric acid scrubbing again 4 times, and is flotation under 1.9 the condition at pH.Can to obtain the rate of recovery with the method be 90%, contain zircon is 98% concentrate.Though index that this method obtains is better, because energy consumption and cost height, flow process shortcoming such as complexity has very limited promoting the use of of it.So far, the used collecting agent of flotation zircon has oleic acid, enuatrol, soap, naphthenic soap, oxidation paraffin wax soap, tall oil, kerosene and hydroximic acid etc. from beach placer, these collecting agents mostly are aliphatic acid and soap class thereof, and the uhligite thing is all had the collecting effect, the selectivity extreme difference; Used inhibitor has waterglass, aluminum sulfate and starch etc., and these inhibitor also have inhibitory action to the flotation of zircon except that suppressing titaniferous ore.When adopting above-mentioned collecting agent and inhibitor FLOTATION SEPARATION titanium zirconium ore thing, concentrate quality is poor, the rate of recovery is low, separating effect is not good.Must be equipped with strict process conditions such as ore pulp is heated, long-time stir process, flow process complexity, operation control is inconvenience extremely.
The objective of the invention is for the FLOTATION SEPARATION that solves zircon and titaniferous and other non-zirconium ore thing, simplify existing complicated sorting process, and under a kind of normal temperature condition that proposes from beach placer simple, the effective flotation separation method of diffeential floatation zircon.
Flotation raw ore of the present invention is the magnetic tailing of beach placer after magnetic separation, i.e. zirconium chats, its essential mineral have zircon, rutile, ilmenite, white titanium ore, anatase, monazite and quartz etc.
The invention is characterized in from the process of the magnetic tailing flotation zircon of beach placer and added 1-hydroxyl-alkyl-1, the two phosphonic acids of 1-,
R is C in the formula
6-8Alkyl is as the highly selective collector of zircon.In the two phosphonic acids of alkyl hydroxy two phosphate radical-PO are arranged
3H
2The solid group of parent, its unique spatial geometric shape causes zircon ZrSiO
4Lip-deep Zr ion has higher selective complexation effect, and to the complexing of Ti in the titaniferous ore or Fe ion extremely a little less than, make it produce selective absorption on the surface of zircon.Another feature of the present invention is with the two phosphonic acids diffeential floatation zircon of alkyl hydroxy the time, adds humic acid or its esters, and its esters is sodium salt or ammonium salt-as the inhibitor of titaniferous ore preferably.Humic acid or its esters have stronger chelation to Ti or Fe plasma, can eliminate the adverse effect of metal ion such as Mg and Ca in the ore pulp, thereby strengthened titaniferous ore and quartzy inhibition, regulated foam state, reduced the mechanical entrainment of foam, the perfect effect of the two phosphonic acids diffeential floatation zircons of alkyl hydroxy.
The addition of the two phosphonic acids of alkyl hydroxy is generally 400～800 gram/tons, roughly selects with 300～600 gram/tons and is advisable, and scans with 100～200 gram/tons and is advisable.The addition of humic acid or its esters is advisable with 300～800 gram/tons, adds the place and is roughly selecting, scanning with selected and all can.Very big during the two phosphonic acids diffeential floatation zircon of alkyl hydroxy with the slurry pH relation, generally with the pH value of sulfuric acid adjusting ore pulp below 4.2.
Embodiment:
With method of the present invention to containing 26.5%ZrO
2And 11.5%TiO
2The magnetic tailing of beach placer carried out the small-scale test of flotation zircon.Its process is, with the pulp density of magnetic tailing furnishing 30%, adds sulfuric acid and stirs 3 minutes, adds the two phosphonic acids 600 gram/tons of alkyl hydroxy and controls pH values of pulp below 4.2, stirs 3 minutes, and flotation got zircon in 3 minutes and roughly selects concentrate.Add the two phosphonic acids 200 gram/tons of alkyl hydroxy again in flotation cell, control pH values of pulp and to roughly select operation identical, stirred 2 minutes, flotation 3 minutes must the zircon scavenger concentrate.Roughly select and scavenger concentrate is merged into zircon ore concentrate.PH less than 4.2 extensive acid medium in, zircon ore concentrate contains ZrO
2Greater than 61.5%, the zircon rate of recovery greater than 99%, the titanium dioxide rate of recovery is less than 10%.Once can obtain to contain ZrO easily as if selected again
2Zircon concentrate greater than 65%.In order to improve the quality of zircon ore concentrate, reduce the concentrate content of titanium dioxide, before alkyl hydroxy pair phosphonic acids add when above-mentioned roughly selecting, add 300-800 gram/ton humic acid and its esters and stir 3 minutes to strengthen inhibition titaniferous and other non-zirconium ore thing.This makes the TiO of zircon ore concentrate
2Content, 4.4% during from the two phosphonic acids of independent use alkyl hydroxy reduced to below 0.8%, and the rate of recovery of zircon remains unchanged.
