Abstract
Disclosed is a preparation method of an auxiliary collector for increasing recovery rate of gold and silver in tennantite. The preparation method includes: mixing acetic acid, hydrochloric acid and water according to a mass ratio of 1-2:1-2:2-5 to obtain a solution 1, adding sodium oleate into the solution 1 according to a mass ratio of 1-2:2-5, and stirring at temperature of 80-85 DEG C until being dissolved to obtain a solution 2; adding phosphate into the solution 2 according to a mass ratio of 1-2:3-7, and enabling reaction under a condition of 3-4Mpa to obtain a liquid preparation which is the auxiliary collector.
Description
One, technical field
The present invention relates to a kind of preparation method improving the supplementary catching agent of recovery of gold and silver in 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 reclaiming mineral and be tennantite and gold and silver content being higher, adopt above collecting agent then not obvious to the recovering effect of gold and silver again, the rate of recovery of general gold and silver is only 50 ~ 60%, and 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.How to prepare the supplementary catching agent improving recovery of gold and silver in tennantite is the problem that concern is compared in domestic and international ore dressing circle always.
Three, summary of the invention
The object of the invention is to a kind of preparation method improving the supplementary catching agent of recovery of gold and silver in tennantite, the supplementary catching agent that the method prepares can improve the recovery of gold and silver of association in tennantite.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of preparation method improving the supplementary catching agent of recovery of gold and silver in tennantite, comprise the steps: first by acetic acid, hydrochloric acid and water acetic acid in mass ratio: hydrochloric acid: water=1 ~ 2:1 ~ 2:2 ~ 5 are mixed to get solution 1, then enuatrol in mass ratio=1 ~ 2:2 ~ 5 are added in solution 1, be stirred under temperature 80 ~ 85 DEG C of conditions and dissolve to obtain solution 2; Then add in solution 2 by phosphoric acid ester in mass ratio=1 ~ 2:3 ~ 7, reaction under 3 ~ 4Mpa condition and the liquid preparation that obtains are the supplementary catching agent of recovery of gold and silver in described raising tennantite.
The application of supplementary catching agent in flotation of recovery of gold and silver in described raising tennantite, actual conditions is: during flotation, slurry pH is 8.5 ~ 9; In floatation process, ore ore grinding is dissociated to mineral monomer, then adds activator, then add tennantite collecting agent, described supplementary catching agent, finally add the agent that spumes and collecting is carried out to tennantite and gold and silver.
The total consumption of described auxiliary collecting is: 50 ~ 60g/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, the supplementary catching agent adopting the present invention to prepare is soluble in water, and has good selective and resistance to low temperature, can improve recovery of gold and silver in tennantite,
2, dosing is few.
