Description
First, technical field
The present invention relates to a kind of preparation method of barite mineral collector, it is adaptable to the more barite of containing calcium silicon stone-like pulse
Ore deposit.
2nd, background technology
The ore dressing of barite mineral is reclaimed and typically adopts reselecting method, the such as gravitational separation equipment such as shaking table, spiral chute to carry out back
Receive, but when barite mineral middle arteries stone ore thing is mainly quartz, calcium carbonate mineral, barite is reclaimed then not using reselecting method
Ideal, its reason are that quartz mineral proportion is relatively close to barite proportion, now if reclaiming barite using method for floating,
The inhibitor good to silico-calcium mineral selectivity is not only needed, and also needs to the good collecting agent of counterweight spar mineral selectivity.
3rd, content of the invention
It is an object of the invention to provide a kind of preparation method of barite mineral collector, the collecting agent being prepared into is to silicon
Calcium mineral without collecting act on, can efficient recovery gangue mineral be silicon, the barite mineral of calcium mineral.
The present invention is employed the following technical solutions and reaches above-mentioned purpose：A kind of preparation method of barite mineral collector, bag
Include following steps：With two or three in Semen arachidis hypogaeae, Brassica campestris L bank up the roots of seedlings, pinaster bank up the roots of seedlings and pine bark as raw material, dry, crush, cross 80
Mesh sieve, is taken in mass ratio：Powder:Diethylamine:Water=2～3:2～4:6～10,150～160 DEG C are heated to, nitrogen gas stirring is passed through
3.5～4h of reaction, is cooled to less than 55 DEG C, filters, takes filtrate and be centrifuged with centrifugal precipitation mechanism, and the supernatant is subtracted
Pressure distillation, obtains buff concentrated solution, heats, solvent is evaporated in 75～80 DEG C of water-baths, and the thick liquid for obtaining is in temperature 50
DEG C vacuum drying oven in dry, obtain yellowish-brown sticky solid, obtain after being completely dried yellow powder be barite mineral
Collecting agent.
It is 10.5～11 that during flotation, sodium carbonate adjusts slurry pH, in floatation process, by Ore ore grinding to mineral monomer solution
Then plus 2# oil bubbles from rear, add waterglass to make silico-calcium mineral inhibitor, the collecting agent is added by 800～900g/t,
Agent carries out collecting to barite mineral.
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each component content percent sum is
100%.
Particularly advantage of the invention is：
1st, using the present invention prepare collecting agent to silico-calcium mineral without collecting act on, can efficient recovery stone-like pulse be silicon, calcium
The barite mineral of mineral, make barite mineral obtain the preferable response rate and concentrate grade.
2nd, dosing is few, nontoxic pollution-free.
4th, specific embodiment
