Description
Technical field
The present invention relates to golden production technical fields, are a kind of purification of leaching liquor simple and effective, almost without equipment investment
Technology, in particular to a kind of your liquid impurity-removing method of indirect heap leaching of gold ores technique.
Background technique
In gold heaping leaching production, leachate recycles for a long time can add up the impurity such as a large amount of copper, mercury, zinc, nickel, seriously affect
Continuing the effect leached, tail washings is discharged in general mine, will cause environmental pollution, and the industry generallys use vulcanized sodium removal of impurities, although
Mode is identical, but vulcanized sodium removal of impurities requires PH to be acidified before 3-6, removal of impurities, again adjusts PH after removal of impurities then useless to 9-11
Water could be recycled, while vulcanized sodium rate of deposition is lower.It is at high cost using vulcanized sodium impurity-removing method complex process, while acid
Property removal of impurities when, solution generate hydrogen cyanide gas, one causes cyaniding sodium loss, and two cause environmental pollution, third is that if recycling Cymag
The complication of removal of impurities process can be increased again.
Summary of the invention
It is an object of the invention to disclose a kind of method of your liquid removal of impurities of indirect heap leaching of gold ores technique, reality may be implemented
Existing leachate is recycled for a long time and zero-emission, keeps impurity low concentration state in leachate, improves leaching rate, recycling impurity gold
Belong to.
The technical solution of the present invention is as follows:
A kind of your liquid impurity-removing method of indirect heap leaching of gold ores technique active carbon is added in the expensive liquid of heap leaching of gold ores, by 10-
30 days, by the active carbon of adsorption saturation, which contained golden Au, silver Ag, copper Cu, mercury Hg, nickel, waits taking-up, is desorbed,
Active carbon after desorption is carried out pickling processes by the active carbon after obtaining desorption waste water and desorption, and treated active carbon can be with
It reuses, the acid waste water that pickling processes obtain, and the smelting that desorption waste water and gold mud generate when being smelted is useless
Water is put into sedimentation basin, carries out removal of impurities processing using efficient impurity removal agent, and treated, and water can return to production cycle use, precipitating
Object carries out filters pressing, storage.Using the adsorption function of active carbon, by copper, tribute, nickel, lead, etc. in impurity absorptions to active carbon, then benefit
With the desorption electrodeposition system of gold loaded carbon, carry out the operations such as pickling, smelting of gold slurry, impurity enter desorption waste water, pickling waste waters with
And in smelting wastewater, above-mentioned foreign ion is then precipitated using cleaner, plays the purpose of your liquid removal of impurities indirectly.
Preferably, the efficient impurity removal agent is the mixture of lime sulfur or lime sulfur and polyaluminium sodium.
The lime sulfur be added lime 0.5-2 parts, 1-3 parts of sulphur powder, 8-12 parts of water mixture boil,
Preferably, the lime sulfur be 1 part of lime, 2 parts of sulphur powder, 10 parts of water mixture boil, can also
From the purchase of Lianyun Harbour Lan Xing Industrial Technology Co., Ltd.
The efficient impurity removal agent, lime sulfur and polyaluminium sodium weight ratio are 7-13:0.5-3, preferably 10:1.
Need to adjust pH value between 3-12 before using efficient impurity removal agent, it is preferred that PH value is between 5-12.If
It is cleaned with vulcanized sodium, PH is adjusted to 5-6, and the PH range that the cleaner is applicable in is wide, between PH=3-12, can effectively remove
It is miscellaneous.
It can also be taken out, preferably 20 days for active carbon to be added in the expensive liquid of heap leaching of gold ores, by 17-23 days.
The present invention uses efficient impurity removal agent, the impurity such as dust removal rate high, settling velocity fast, copper, mercury, zinc, nickel, the PH of adaptation
Value range is wide, and does not influence the leaching of gold.Realization leachate is recycled for a long time and zero-emission；Keep impurity in leachate low
CONCENTRATION STATE improves leaching rate；Foreign metal recycling.The efficient impurity removal agent belongs to low toxic and environment-friendly medicament, cheap, has extensively
Prospects for commercial application.Processing method of the present invention is simple and efficient, and reagent consumption is the half of vulcanized sodium, also without adjusting acid, alkali tune
Expense, investment and operation cost all substantially reduce, according to leachate impurity situation, can continuously be interrupted, it is convenient, flexible, for a long time
Guarantee that leachate is clean and is recycled, really realizes technique of zero discharge.
In impurity absorption to gold loaded carbon, impurity also obtains entering in desorption waste water, acid waste water and smelting wastewater in desorption,
These three waste water are handled using efficient impurity removal agent, treated, and water can return to production cycle use.Scheme is implemented simply,
Using sedimentation basin, almost without equipment investment.
The present invention uses High-rate sedimentation agent, compares and has the advantage that compared with vulcanized sodium
(1) sedimentation effect is good, rate of deposition can achieve copper >=95%, nickel >=85%, mercury >=95%, zinc >=95%, iron >=
95%；And with vulcanized sodium impurity-removing precipitating rate copper >=75%, nickel >=60%, mercury >=75%, zinc >=85%, iron >=85%.
(2) pH range is wide.
(3) process is simple, Cymag free of losses, economic and environment-friendly.
