Abstract
The invention discloses a method for preparing a tennantite collecting agent. The method comprises the steps that first, sodium sulfide, sodium hydroxide and water are mixed to form a first solution according to the mass ratio of 1-2:1-2:2-5, then, sodium alcohol ether sulphate with the concentration ranging from 25% to 30% is added to the first solution according to the mass ratio of 1-2:3-7, mixing is carried out under the temperature ranging from 70 DEG to 75 DEG till the sodium alcohol ether sulphate is dissolved, and a second solution is obtained; phosphonolipid and fuming sulphuric acid are added to the second solution according to the mass ratio of 1-2:1-3:3-7, reaction is carried out under the condition of 2-3 Mpa, and the obtained liquid agent is the tennantite collecting agent.
Description
One, technical field
The present invention relates to a kind of preparation method of tennantite collecting agent, particularly for the preparation method of the collecting agent of tennantite.
Two, background technology
It is all generally adopt sulfuric acid or copper sulphate first to activate that the flotation of copper sulfide both at home and abroad is at present reclaimed, and then add xanthate, black powder, sulphur nitrogen etc. and carry out flotation collecting, the flotation recovery rate of sulphide ore is between 85 ~ 92%, and collecting effect is ideal.But when recovery mineral are tennantite, then adopt above collecting agent then DeGrain, its reason is: on the one hand, and tennantite floatability is good not as other copper sulfide; On the other hand, because arsenic ion is oxidizable compared with copper ion, affect its floatability; Again, there are a small amount of zinc, iron ion to exist with isomorph in tennantite and affect its floatability.The selective copper collector how preparing tennantite is the problem that concern is compared in domestic and international ore dressing circle to improve the rate of recovery of tennantite always.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of tennantite collecting agent, the collecting agent be prepared into by the method can realize tennantite efficient flotation separation and reclaim under the condition adding a small amount of copper sulphate for activation.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of preparation method of tennantite collecting agent, comprise the steps: first by vulcanized sodium, NaOH and water vulcanized sodium in mass ratio: NaOH: water=1 ~ 2:1 ~ 2:2 ~ 5 are mixed to get solution 1, then sodium sulfate of polyethenoxy ether of fatty alcohol in mass ratio=1 ~ 2:3 ~ 7 of 25 ~ 30% are added in solution 1, be stirred under temperature 70 ~ 75 DEG C of conditions and dissolve to obtain solution 2; Then add in solution 2 by phosphoric acid ester, oleum in mass ratio=1 ~ 2:1 ~ 3:3 ~ 7, the liquid preparation be obtained by reacting under 2 ~ 3Mpa condition is described tennantite collecting agent.
During flotation, slurry pH is 8.5 ~ 9; In floatation process, ore ore grinding is added gangue inhibitor after mineral monomer dissociates, then adds activator, then add described collecting agent, finally add foaming agent and collecting is carried out to tennantite.
The total consumption of collecting agent is: 80 ~ 100g/t.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Concrete advantage of the present invention is:
1, adopt the collecting agent that is prepared into of the present invention can collecting tennantite, soluble in water, and there is good selective and resistance to low temperature.
2, dosing is few.
