Abstract
The invention discloses a method for desorption and gold extraction in a flotation technology. The method comprises the steps that gold bearing carbon is placed in a desorption column for desorption elution to obtain a desorption solution, and filter-pressing grading is carried out on the desorption solution through a filter press to obtain clear filter liquor and gold bearing filter residues; and then the filter residues are injected into an electrolytic cell for electrolysis, gold in the filter liquor is enriched into the electrolytic cell to form gold mud, the filter liquor losing gold is changed into electrolytic barren liquor to return into the desorption column, and desorption elution treatment continues to be carried out on the gold bearing carbon. The gold mud is treated through a smelting process to obtain a gold product, and the gold bearing filter residues are dried and incinerated to obtain the gold product through smelting. The recovery rate of the gold and the fineness of the gold mud can be improved, the grade of desorption barren carbon can be lowered, and economic benefits can be improved.
Description
Technical field
The present invention relates to a kind of desorb carry gold method, particularly a kind of in gold industry from gold floatation concentrate cyanidation CIL method desorb carry gold method.
Background technology
In gold industry, cyanidation CIL method is applied to the technique that gold floatation concentrate carries gold and puts into practice at Jilin gold mine at late nineteen eighties, and in the early 1990s application, for China's gold mine opens a new outlet.The method refers to that ore obtains gold ore after floatation process process, then gold ore is formed gold loaded carbon on the activated carbon through the absorption of cyanidation CIL technique, gold loaded carbon is carried out the series of processes method that gold is carried in desorb.
In floatation process, because gold ore is difficult to clean for the organism such as flotation reagent and flocculation agent wash-out in reagent removal washing process, therefore the gac in cyanidation CIL operation stage is organism such as meeting absorbed portion flotation reagent and flocculation agent etc. while ADSORPTION OF GOLD, and in desorbing electrolytic process, produce floating bubble in small, broken bits.Gold and the electrolysis cathode fiber in small, broken bits of the powdered carbon of gold loaded carbon adhesion, breeze and partial reduction can be all that carrier is floating at the upper surface of electrolytic solution with bubble, make the short circuit of electrolysis cathode and anode transient switching, thus generation steel wool comes off and floats golden phenomenon, make the poor charcoal rising of desorb, gold recovery reduction, and cause the loss of gold.
Summary of the invention
The object of this invention is to provide a kind of from floatation process desorb carry gold method.
Method of the present invention is: first gold loaded carbon is carried out desorb wash-out, and the stripping liquid after wash-out carries out press filtration classification, obtains clear filtrate and filter residue; Then filtrate is carried out Electrolysis enrich, generate gold mud and lean electrolyte; Lean electrolyte is returned gold loaded carbon wash-out flow process, circulating desorption wash-out gold loaded carbon; Electrolysis gold mud is by obtaining golden product after smelting technology process; After the filter residue oven dry ashing of press filtration classification, obtain golden product by smelting technology process.
Beneficial effect of the present invention: improve gold recovery and gold mud quality, reduces the poor charcoal gold grade of desorb, increases economic efficiency.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Embodiment
Refer to shown in Fig. 1, gold loaded carbon is put into desorption column and carry out desorb wash-out and obtain stripping liquid, and with pressure filter, stripping liquid is carried out press filtration classification, obtain the filtrate of clarifying and the filter residue containing gold; Then filtrate is injected electrolyzer and carry out electrolysis, the gold in filtrate is enriched in electrolyzer and forms gold mud, the filtrate losing gold becomes lean electrolyte and returns in desorption column and continue to carry out the process of desorb wash-out to gold loaded carbon.Wherein, gold mud obtains golden product after smelting technology process; And obtain golden product containing after the filter residue oven dry ashing of gold through smelting.
Claims (1)
1. from floatation process, a method for gold is put forward in desorb, and the method is: first gold loaded carbon is carried out desorb wash-out, and the stripping liquid after wash-out carries out press filtration classification, obtains clear filtrate and filter residue; Then filtrate is carried out Electrolysis enrich, generate gold mud and lean electrolyte; Lean electrolyte is returned gold loaded carbon wash-out flow process, circulating desorption wash-out gold loaded carbon; Electrolysis gold mud is by obtaining golden product after smelting technology process; After the filter residue oven dry ashing of press filtration classification, obtain golden product by smelting technology process.
