Abstract
The invention discloses a zirconite beneficiation combined reagent and a beneficiation method, wherein the reagent added in each ton of raw ore is composed of the following raw materials by weight: the zirconite beneficiation combined reagent provided by the invention has the advantages that the collecting performance and selectivity of the zirconite are good, and the grade and recovery rate of the zirconite concentrate can be further improved. When the material contains a small amount of fine mud or clay minerals in the flotation operation, water glass is added to serve as an inhibitor of the fine mud or clay minerals.
Description
Technical field
The invention belongs to technical field of mineral processing, and in particular to a kind of zircon ore dressing combination medicament and beneficiation method.
Background technique
Zircon is positive zirconium silicate, chemical molecular formula ZrSiO4, it is one of the most common type in Zr-containing minerals.Zircon mine
Bed is mostly beach placer, and in the heavy sand containing zircon, usual symbiosis has the weight mine such as magnetic iron ore, ilmenite, rutile, monazite
Object.The explored zircon ore reserves in China occupies the 5th, the world, and zircon is a kind of critically important nonmetal mineral resource, main
To be used as the raw material of zirconates refractory brick, it may also be used for hot investment casting molding sand and production ceramic utensil.
Common beneficiation method: frequently with gravity treatment, magnetic separation, electrostatic separation and flotation, gravity treatment is sorted according to mineral density difference,
Heavy mineral is separated with gangue mineral (predominantly quartz and feldspar), it is then normal further according to mineral specific susceptibility difference, dielectric
Number difference etc. is separated zircon with other heavy minerals using the techniques such as magnetic separation, electric separation.The common collecting agent of zircon flotation is
Fatty acid (oleic acid, enuatrol) etc., ore pulp regulator are sodium carbonate, and inhibitor is sodium metasilicate, and activator is vulcanized sodium and a huge sum of money
Belong to salt (zirconium chloride, iron chloride).Also useful oxalic acid adjusts ore pulp to acidity, with amine collector flotation.
High-purity zircon is sorted using techniques such as gravity treatment, magnetic separation, electric separations, since equipment sharpness of separation is poor, zircon essence
Zr(Hf in mine) O2Content is extremely difficult to 65%.Even if concentrate Zr(Hf) O2Content can reach 65%, but lose more recycling
Rate causes the waste of resource.Zircon routine collecting agent oleic acid, enuatrol are selectively poor, and concentrate is also extremely difficult to higher
Quality requirement.
(1) latter stage of Jin Dynasty plum etc. (Jiangxi zirconium hafnium mine Experimental study on ore dressing, mining and metallurgy, 2009,4:17-19) describes Jiangxi zirconium
Hafnium mine contains (ZrHf) O21.97%, it is sorted using gravity treatment, thick using spiral chute, scan, spiral shell slips primary cleaning, gained
Spiral shell slips rough concentrate and shaking table one is used slightly to sweep an essence again, and obtaining zirconium hafnium grade is 57.72%, the zirconium hafnium essence that the rate of recovery is 65.60%
Mine.
(2) Tang Pingyu etc. (recycle the beneficiation test of iron and monazite zircon from garrulous mica tailing, metal mine,
2012,10:153-156) it describes using the selection by winnowing tailing of Hebei province Lingshou County garrulous mica ore as object, integrates back
Receive the beneficiation test of wherein iron mineral, monazite and zircon.The result shows that the tailing, which is first passed through table concentration, isolates weight
Sand sorts heavy sand using low intensity magnetic separation-wet high-intensity magnetic separation-dry high-magnetic separation-table concentration joint process, can
Obtain iron ore concentrate, the monazite concentrate that REO grade is 61. 13% and (Zr, Hf) O that Iron grade is 60. 86%2Grade is
60.38% zircon ore concentrate, the metal recovery rate of 3 kinds of concentrate are respectively 74. 27%, 70. 36% and 65. 64%.
(3) Chen Yuanqing (improving the research of zircon recovery rate in ore-dressing, non-ferrous metal ore part, 1987,32-35) is introduced
It by the research to zircon floatability in beach placer, and produces and confirms through Hainan Qinglan titanium ore, by traditional one electricity of weight
The electric magnetic Complicated Flow of one magnetic one is changed to the quick-reading flow sheets of floating one electricity of a magnetic, improves the rate of recovery of 10-15%, zircon concentrate primes

Summary of the invention
The invention patent is designed to provide a kind of zircon ore dressing combination medicament and beneficiation method, using combination medicament
Zircon rough concentrate is selected again by floatation process, prepares high-purity zircon ore concentrate, zircon recovery rate in ore-dressing is improved, reaches
Comprehensively utilize the purpose of such resource.
The object of the present invention is achieved in the following manner:
The medicament of a kind of zircon ore dressing combination medicament, raw ore addition per ton is made of the raw material of following weight: sulfuric acid
100-2000g, inhibitor 0-500g, collecting agent 100-1000g, inhibitor are waterglass, collecting agent include petroleum sodium sulfonate and
The mass ratio of hydroximic acid, petroleum sodium sulfonate and hydroximic acid is 1:1-10:1.
The hydroximic acid is Salicyl Hydroximic Acid or benzyl hydroximic acid.
The method for carrying out ore dressing using above-mentioned zircon ore dressing combination medicament, the specific steps are as follows:
(1) tail is thrown in gravity treatment enrichment: raw ore is enriched with through gravity treatment, and heavy mineral is separated with gangue mineral, obtains heavy mineral；
(2) heavy mineral removes weak magnetic substance, ferromagnetic substance and conductive material through magnetic separation, electric separation or magnetoelectricity process integration,
Obtain zircon rough concentrate；
(3) flotation, pH values of pulp floatation process: are carried out to zircon rough concentrate using above-mentioned zircon ore dressing combination medicament
In 4-5, sorting number is one roughing for value control, is scanned for 2-3 time, and 2-4 time selected, and chats sequentially return finally obtains high-purity
Zircon ore concentrate.
The gravitational separation equipment used in the step (1) is jigging machine, spiral chute or shaking table.
When material contains a small amount of thin mud or clay mineral in flotation operation, add waterglass as thin mud or clay mineral
Inhibitor.
Compared with the existing technology, zircon ore dressing combination medicament provided by the invention to zircon collecting performance and selectivity compared with
It is good, it can be further improved zircon ore concentrate grade and the rate of recovery.Zircon belongs to positive Silicate Rocks class mineral, and zero point is pH5 ~ 6.05
Between (being 2.5 in individual cases), in acid condition, zircon can be activated by sulfate, quartzy zero point 1.3 ~ 3.7,
Quartz is inhibited under the acid condition of pH value 4 ~ 5.Sulfonate ion is directly in petroleum sodium sulfonate and zirconium ion is with ionic bond
Interaction generates chemisorption, and the gangue minerals such as petroleum sodium sulfonate and quartz are mainly based on physical absorption.Hydroximic acid is also led
If being interacted with hydroximic acid root and zirconium ion with ionic bond generates chemisorption, (zirconium belongs to rare to hydroximic acid with rare metal
Metal) stable chelate can be formed.Petroleum sodium sulfonate and hydroximic acid belong to anionic collector, and anionic collector combination makes
As follows with the mechanism of action: mineral surfaces different zones have different activities, living in the case where different activities pharmaceutical agent combinations use
Property small collecting agent can be adsorbed on the big surface district of activity, remaining unadsorbed empty surface, expression activitiy is small, no
The fixation of the small collecting agent of suitable activity, but the fixation for the collecting agent for being suitble to activity big, simultaneously as the frothing capacity of collecting agent
Difference improves separation index to take into account collecting performance and selectivity.
