Description
First, technical field
The present invention relates to a kind of preparation method of the supplementary catching agent for improving recovery of gold and silver in tennantite.
2nd, background technology
The at present both at home and abroad flotation of copper sulfide is reclaimed and is typically all first activated using sulphuric acid or copper sulfate, then plus xanthate,
Black powder, sulfur nitrogen etc. carry out flotation collecting, and between 85～92%, collecting effect is ideal for the flotation recovery rate of sulphide ore.But
It is when it is tennantite and higher gold silver content to reclaim mineral then then not clear to the recovering effect of gold silver using above collecting agent
Aobvious, the response rate of general gold silver is only 50～60%, and its reason is：On the one hand, tennantite floatability is not as other sulfurations
Copper is good；On the other hand, as arsenic ion is oxidizable compared with copper ion, affect its floatability；Again, have in tennantite a small amount of zinc,
Iron ion is present with isomorph affects its floatability.How the supplementary catching agent that improve in tennantite recovery of gold and silver is prepared
The problem of concern is compared in always ore dressing circle both at home and abroad.
3rd, the content of the invention
It is an object of the invention to a kind of preparation method of the supplementary catching agent for improving recovery of gold and silver in tennantite, should
The supplementary catching agent that method is prepared can improve the recovery of gold and silver of association in tennantite.
The present invention is employed the following technical solutions and realizes above-mentioned purpose：The auxiliary of recovery of gold and silver in a kind of raising tennantite
The preparation method of collecting agent, comprises the steps：First by acetic acid, hydrochloric acid and water acetic acid in mass ratio：Hydrochloric acid：Water=1～2:1
～2:2～5 mix to obtain solution 1, then by enuatrol in mass ratio=1～2:During 2～5 add solution 1, in 80～85 DEG C of temperature
Under the conditions of stir to dissolving to obtain solution 2；Then by phosphate ester in mass ratio=1～2:During 3～7 add solution 2, in 3～4Mpa
Under the conditions of react obtained from liquid preparation be the described supplementary catching agent for improving recovery of gold and silver in tennantite.
Application of the described supplementary catching agent for improving recovery of gold and silver in tennantite in flotation, actual conditions is：
During flotation, slurry pH is 8.5～9；In floatation process, Ore ore grinding to mineral monomer is dissociated, activator is subsequently adding, then
Plus tennantite collecting agent, the supplementary catching agent, finally plus the agent that spumes carries out collecting to tennantite and gold silver.
The auxiliary total consumption of collecting is：50～60g/t.
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, it is soluble in water using the supplementary catching agent for preparing of the invention, and with good selectivity and lower temperature resistance
