Abstract
A kind of preparation method of mineral inhibitor for barite, in molar ratio with epoxychloropropane: trimethylamine=1～2: 2～6 put into boiling flask, place the ice bath pot, behind airtight stirring reaction 2～3h, it is stand-by as intermediate products to get upper strata liquid behind the standing demix, and starch is put into boiling flask, adds intermediate products, make catalyst with HCl solution, add Na by 0.1%～0.2% of total system mass ratio
2SO
4, place 70～85 ℃ of water-baths to add thermal response 3～4h after, dry moisture, the flour that obtains is described inhibitor.Adopt inhibitor of the present invention can effectively suppress barite in the fluorite concentrate, improve the fluorite concentrate grade, and flow process is simple, dosing is few, less energy consumption.
Description
One, technical field
The present invention relates to a kind of mineral inhibitor for barite, particularly when close, need the diffeential floatation fluorite to suppress a kind of mineral inhibitor for barite of barite mineral for fluorite, barite association and ore content.
Two, background technology
At home and abroad fluorite generally adopts the inhibitor of waterglass as gangue mineral, and oleic acid or enuatrol reclaim as the collecting agent of fluorite mineral.But when grade is close when gangue mineral in the fluorite mineral is barite mineral and ore content and firefly, the general reselecting method elder generation recovery section barite that adopts must weigh brilliant concentrate, mine tailing adds a large amount of waterglass as mineral inhibitor for barite after thickening, make collecting agent with oleic acid and reclaim the fluorite mineral again, so not only technological process complexity, equipment investment is big, and fluorite, the barite rate of recovery are not high.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of mineral inhibitor for barite, the inhibitor that is prepared into can suppress different grade barite mineral, improves the rate of recovery and the concentrate grade of fluorite in fluorite, the barite associated minerals.
The present invention achieves the above object by the following technical solutions: a kind of preparation method of mineral inhibitor for barite, may further comprise the steps: in molar ratio with epoxychloropropane: trimethylamine=1～2: 2～6 put into boiling flask, place the ice bath pot, behind airtight stirring reaction 2～3h, it is stand-by as intermediate products to get upper strata liquid behind the standing demix.Starch is put into boiling flask, add described intermediate products, make catalyst, add Na by 0.1%～0.2% of total system mass ratio with HCl solution
2SO
4, place 70～85 ℃ of water-baths to add thermal response 3～4h after, the resulting flour of final drying moisture is described inhibitor.
Slurry pH is 6～7 during flotation; In the floatation process, after ore ore grinding to mineral monomer dissociated, add inhibitor, and then collecting agent and foaming agent.
Dosing is: 1000～1500g/t.
Outstanding advantage of the present invention is:
1, barite there is the good restraining effect, effectively improves the fluorite concentrate grade.
2, dosing is few, nontoxic pollution-free.
Four, the specific embodiment
Embodiment 1
A kind of preparation method of mineral inhibitor for barite comprises the steps:
In molar ratio with epoxychloropropane: trimethylamine=put into boiling flask at 1: 2, place the ice bath pot, behind the airtight stirring reaction 2h, it is stand-by as intermediate products to get upper strata liquid behind the standing demix.Starch is put into boiling flask, add described intermediate products, make catalyst, add Na by 0.1% of total system mass ratio with HCl solution
2SO
4, place 70 ℃ of water-baths to add thermal response 3h after, dry moisture obtains flour, is described inhibitor.
Embodiment 2
A kind of preparation method of mineral inhibitor for barite comprises the steps:
In molar ratio with epoxychloropropane: trimethylamine=put into boiling flask at 1: 3, place the ice bath pot, behind the airtight stirring reaction 3h, it is stand-by as intermediate products to get upper strata liquid behind the standing demix.Starch is put into boiling flask, add described intermediate products, make catalyst, add Na by 0.2% of total system mass ratio with HCl solution
2SO
4, place 85 ℃ of water-baths to add thermal response 4h after, dry moisture obtains a kind of flour, is described inhibitor.
Embodiment 3
The application example that present embodiment suppresses the barite mineral for embodiment 1 described inhibitor.
1, raw mineral materials
Ore deposit, Guizhou, treating capacity are 100 tons/day, and it is produced, and fluorite content is 33.92% in the used ore, and barite is 35.33%, gangue mineral is based on silica, and other has a small amount of calcium carbonate to exist.
2, regime of agent and operating condition: waterglass 300g/t, oleic acid 500g/t, inhibitor 1000g/t.Slurry pH is 6～7 during flotation.In the floatation process, at first add after waterglass to ore mill dissociates ore ore grinding to mineral monomer, adding oleic acid again carries out bulk flotation to fluorite, barite to the flotation device and gets bulk concentrate, inhibiting suppresses the barite mineral then, through seven selected fluorite concentrates that get, the anti-floating again barite concentrate that then gets of cleaner tailings.Carried out 100t/d industry expanding test in a year by above-mentioned technological parameter, show and adopt above technology and medicament condition effectively will hang down product fluorite, barite recovery, giving ore deposit fluorite content is 33.92%, barite is under 35.33% condition, through one roughing scan for twice and seven times selected, flotation concentrate fluorite grade is 95.8%, and the rate of recovery reaches 78.5%; Cleaner tailings again reverse flotation to get grade be 92.3%, the rate of recovery reaches 75.2% barite concentrate
Embodiment 4
The application example that present embodiment suppresses the barite mineral for embodiment 2 described inhibitor.
1, raw mineral materials
The ore deposit, Guizhou, fluorite content is 37.87% in the ore, barite is 45.43%, silica 1 5.78%, calcium carbonate 3.54%.
2, regime of agent and operating condition: waterglass 400g/t, oleic acid 700g/t, barite inhibitor 1500g/t.Slurry pH is 6～7 during flotation, in the floatation process, at first add after waterglass to ore mill dissociates ore ore grinding to mineral monomer, adding oleic acid again carries out bulk flotation to fluorite, barite to the flotation device and gets bulk concentrate, inhibiting suppresses the barite mineral then, through eight selected fluorite concentrates that get, the anti-floating again barite concentrate that then gets of cleaner tailings.Carried out the 200t/d pilot production by above-mentioned technological parameter, show and adopt above technology and medicament condition effectively fluorite, barite to be reclaimed, giving ore deposit fluorite content is 37.87%, barite is under 45.43% condition, selected through eight times, flotation concentrate fluorite grade is 95.35%, and the rate of recovery reaches 76.51%; Cleaner tailings again reverse flotation to get grade be 92.18%, the rate of recovery reaches 75.66% barite concentrate.
