Abstract
The present invention relates to combination medicine of differential flotation zircon with a froth flotation method from zircon materials, which uses dodecylbenzenesulfonic acid (sodium) as a collector. The present invention uses one of tetradecene, dipentene, longifolene and secondary octyl alcoho as an auxiliary collector, and uses sodium fluorosilicate, oxalic acid dihydrate, disodium hydrogenorthophosphate and carboxymethyl cellulose as inhibitors. The present invention can obtain high-purity low-titanium zircon concentrate with 66.5% of (Zr-Hf)O-[2] and less than 0.06% of TiO-[2] through floating common zirconium concentrate, and the recovery rate is from 77 to 89%. The present invention can obtain common zirconium concentrate with 60 to 65% of (Zr-Hf)O-[2] through floating low zirconium materials, and the recovery rate can reach more than 93%.
Description
The present invention relates to a kind of combination medicament of from contain the zircon material, using froth flotation method diffeential floatation zircon.Be particularly suitable for (containing (ZrHf) O from common zircon concentrate
260～65%) floatingly select high-purity low titanium zircon ore concentrate in.
Neopelex is used for floatation process, generally be as foaming agent, rarely seen Japan has factories and miness to be used for barite collecting agent and the U.S. has the people to be used as the report (" external metallic ore ore dressing ") of phosphate ores collecting agent, 1975, № 7-8, the 72-73 page or leaf; United States Patent (USP) № 3164549), neopelex there is report as the Shang Weijian of zircon collecting agent.
The objective of the invention is to make the main collecting agent foaming agent of holding concurrently, and be equipped with several medicaments such as tetradecene and form a complete flotation agent system with DBSA (sodium).Be used for the various materials that contain zircon of sorting effectively,, particularly produce the quality raw materials of color picture tube glass screen with the zircon powder so that produce the zircon ore concentrate product of different purposes, all size, and the special cermacis raw material.
Main points of the present invention are to add following several medicaments in flotation zircon process:
1. DBSA (sodium)
As the collecting agent foaming agent of holding concurrently.This medicament does not need to purify or reprocessing for synthetic detergent factory produces the intermediate product of civilian synthetic detergent powder, can directly use.Contain the working substance composition in the sulfonic acid and be about 95%, containing the working substance composition in its sodium salt is 32%, so the sulfonic acid consumption is about 1/3rd of its sodium salt.DBSA or its sodium salt are all applicable.
2. tetradecene, dipentene, longifolene, secondary octanol
As the supplementary catching agent foam modifier (defoamer) of holding concurrently.The present invention adopts tetradecene, dipentene, longifolene, a kind of and DBSA (sodium) in the secondary octanol is united when using, significantly improved the collecting ability of DBSA (or its sodium salt) to zircon, thereby improved the rate of recovery of zircon concentrate and reduced the consumption of DBSA (or its sodium salt), can reduce simultaneously the foaming characteristic of DBSA (or its sodium salt) again, make its foam volume moderate, be convenient to operation: the viscosity that can reduce foam again, gone in the froth pulp by mechanical entrapment thereby reduce impure mineral, help improving concentrate quality.
3. prodan, oxalic acid, sodium hydrogen phosphate, carboxymethyl cellulose
Make inhibitor, be used for suppressing the associated mineral of zircon.Can grasp flexibly during concrete the application, when material especially easily selects (for example flotation zircon from quartz) and concentrate quality is required to use prodan to get final product separately when not too high; And require when very high when the difficult separation of material and to concentrate quality, then above two kinds, three kinds even four kinds of inhibitor must be used simultaneously.
4. sulfuric acid, NaOH
Make pH value conditioning agent, generally can not use.Just in slurry pH greater than just using sulfuric acid at 5.5 o'clock; Slurry pH is less than just using NaOH at 3 o'clock.The present invention requires to control slurry pH flotation between 3～5.5.
The preparation of medicament and using method thereof:
DBSA and sodium salt thereof are liquid and pasty state, are made into during use to contain former medicine (the working substance component content: sulfonic acid is about 95%, its sodium salt about 32%) 1～5%(concentration expressed in percentage by weight, and be as follows) the aqueous solution.
Tetradecene, dipentene, longifolene, secondary octanol: liquid, former medicine directly adds.
Prodan: solid, be made into 0.5% the aqueous solution and add, also can directly add former medicine.
Sodium hydrogen phosphate: solid, be made into 1～5% the aqueous solution and add, also can directly add former medicine.
Carboxymethyl cellulose: solid is made into 0.1～0.5% the aqueous solution and adds.
Oxalic acid: solid, be made into 1～5% the aqueous solution and add, also can directly add former medicine.
Sulfuric acid, NaOH: be made into 1～5% the aqueous solution and add.
Dosing generally following (gram/ton):
DBSA: roughly select 40～500 selected 7～300
Neopelex: roughly select 100～1500 selected 20～800
Tetradecene, dipentene, longifolene: roughly select 20～800 selected 10～200
Secondary octanol: roughly select 20～800 selected 10～200
Prodan roughly selects 200～1500 selected 200～1000
Sodium hydrogen phosphate roughly selects 20～1000 selected 20～600
Carboxymethyl cellulose roughly selects 0～5 selected 1～10
Oxalic acid roughly selects 100～500 selected 50～300
Sulfuric acid is decided on pH value situation, and pH≤5.5 get final product.
NaOH is decided on pH value situation, and pH 〉=3 get final product.
During flotation, earlier prodan, oxalic acid, sodium hydrogen phosphate, carboxymethyl cellulose are added tank diameter, stirred 3～15 minutes, add DBSA (sodium) then, and a kind of in the tetradecene, dipentene, longifolene, secondary octanol, stir and got final product flotation in 1～5 minute.
The present invention generally adopts one roughing, a flotation flowsheet to triple cleaning.When from the material of especially easily choosing, floatingly selecting common zircon concentrate, only need one roughing and do not want selected can achieving the goal.Select material then need roughly select or increase for twice for difficulty and scan operation.
Adopt the present invention (to contain (ZrHf) O with common zircon concentrate
