Description
Technical field
The present invention relates to metallurgical industry processing technology field, specifically a kind of extraction that can be improved gold solution rate is helped
Agent.
Background technique
In golden production industry, extraction of gold by cyanidation is generallyd use at present.During cyanidation gold-extracted, gold solution rate
Speed, two broad aspects are depended primarily on, first is that the size of the contact area of gold and gold leaching solution, second is that in gold leaching solution
The concentration of dissolved oxygen.In order to improve the rate of recovery of gold, the grinding rate of ore generally all using extraction time is extended, is improved in various regions
Etc. modes realize, cause the period entirely produced long.Production technology is drenched for pond leaching or heap, a production cycle is often
It requires to take a month time of 3-6；And production technology is starched for carbon, the production cycle is mostly at 30 more than hour.Therefore, raw
Produce the universal phenomenon that period length is this industry.
In gold dust or rock gold mine containing bright gold, golden particle be often it is bigger, most of gold is all exposed
Comparison it is sufficient.For this kind of ore, common processing method is to use gravity separation method, fewer to use cyaniding, because if
It is taken a long time with cyaniding and needs to be leached, can guarantee all dissolution recycling of more coarse grained gold.
And gravity separation method also has limitation, for the bright gold that some quilts partly wrap up, is not easy to smoothly select, and causes tailings grade to run high.
In electronic component and waste and old circuit board gold refinement industry, since this kind of object outer dimension is not of uniform size, using pond leaching or
Spray process, primary treating capacity is simultaneously few, and the extraction time equally consumed is very long, causes production efficiency not high.
Therefore, during golden production, it is badly in need of a kind of solution rate that can accelerate gold now, shortens extraction time
Extraction auxiliary agent.
The disclosure of background above technology contents is only used for auxiliary and understands inventive concept and technical solution of the invention, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
Summary of the invention
The present invention has that solution rate is slow, extraction time is grown for existing gold extraction process, provides a kind of energy
Solution rate is improved, extraction time is greatly shortened, the gold for accelerating production efficiency extracts auxiliary agent.
In order to achieve the goal above, The technical solution adopted by the invention is as follows:
A kind of extraction auxiliary agent can be improved gold solution rate, the auxiliary agent include the raw material of following parts by weight: tartaric acid
3-8 parts of potassium sodium, 3-8 parts of ammonium citrate, 2-4 parts of soda ash, 2-3 parts of sodium lignin sulfonate, 1-2 parts of lead salt and sulfonation nitrobenzene 4-8
Part.
Preferably, the lead salt include one of plumbi nitras, lead acetate, lead chloride, lead sulfate and basic lead carbonate or
Multiple combinations.
Preferably, it is 2-10:100-180 that the usage amount of the auxiliary agent, which is the mass ratio of auxiliary agent and gold ore agent,.
Preferably, the gold ore agent is the gold ore agent of golden cicada board.
Preferably, the auxiliary agent independent packaging or with the hybrid packed use of gold ore agent.
Preferably, the auxiliary agent by 5 parts of sodium potassium tartrate tetrahydrate, 6 parts of ammonium citrate, 2.5 parts of soda ash, 3 parts of sodium lignin sulfonate,
1.5 parts and 7 parts of sulfonation nitrobenzene of lead acetate；The mass ratio 1:18 of auxiliary agent and gold ore agent when use.
Compared with prior art, it advantages of the present invention and has the beneficial effect that
1, gold provided by the invention extracts auxiliary agent (abbreviation HDGSQ) and is added in gold ore agent, and the solution rate of gold is bright
Aobvious to accelerate, dissolution time greatly shortens, and improves the production efficiency of gold, improves place service efficiency.
2, HDGSQ is added in gold ore agent, compared with Cymag, under the conditions of same dosage, HDGSQ auxiliary agent of the present invention makes
The solution rate for obtaining gold significantly improves, and dissolution time significantly shortens, and will not reduce the recovery rate of gold, and cost is relatively low.
Therefore HDGSQ provided by the invention has good social benefit, ecological benefits and economic benefit for Gold Industry, is suitble to big
Scale is promoted.
