Description
Technical field
The present invention relates to directly carry out plumbous zinc-copper separating flotation comprehensive recovery production method without press filtration after the washing of the direct cyaniding of a kind of high plumbous zinc-copper Gold Concentrate under Normal Pressure and mine tailing.
Background technology
At present, the Gold Concentrate under Normal Pressure of relevant leaded zinc-copper comprehensively reclaims multielement, and the technique of generally taking is after first Gold Concentrate under Normal Pressure being carried out cyaniding, after the washing of ore pulp process and press filtration, then size mixing, then carry out the mixed choosing of plumbous zinc, after the mixed choosing of plumbous zinc Tailings Slurry carry out press filtration, then size mixing, then carry out copper sulphur content from.The press filtration of each section flotation of ore pulp is established one's own system, and does not mutually mix.This sampling technology setting procedure is long, and equipment is complicated, causes production cost high.
Summary of the invention
Technical problem to be solved by this invention is, the direct cyaniding of a kind of high plumbous zinc-copper Gold Concentrate under Normal Pressure and comprehensive recovery production method are provided, and Cyanide Leaching and selecting plumbum and zinc are completed under same ore pulp system, select copper to become separately an individual system, with simplification of flowsheet, reduce production costs.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme that adopts:
The direct cyaniding of a kind of high plumbous zinc-copper Gold Concentrate under Normal Pressure and comprehensive recovery production method is characterized in that carrying out according to following steps:
The first step, cyaniding: concentration is to add sodium cyanide solution in the Gold Concentrate under Normal Pressure ore pulp of 35-40%, mog-400 order 90-92%, make ore pulp liquid contain Cyanide concentration in the 0.7-0.75% scope, your liquid is used for is extracted gold and silver, and cyaniding tailing slurry enters second step;
Second step, choosing lead: cyaniding tailing slurry enters into and selects lead system, pulp density 38-40% after washing, at first pH value 10-11 suppresses zinc with zinc sulfate and sodium carbonate, and consumption is respectively 1Kg/t ore deposit and 3kg/t ore deposit, then add collecting agent butyl xanthate 80g/t ore deposit, diethyldithiocarbamate 80g/t ore deposit; After the lead concentrate ore pulp press filtration that floatingly selects, obtain lead concentrate and filtrate, wherein filtrate is returned to cyanidation system, and the plumbous Tailings Slurry after flotation entered into for the 3rd step;
The 3rd step, select zinc: select the Tailings Slurry after lead, first transferring pH value with sulfuric acid is 9.0-9.5, the hydrogen cyanide that produces in process returns to use after with alkali liquor absorption, then add collecting agent butyl xanthate 200g/t ore deposit to carry out flotation, and zinc concentrate ore pulp and the mine tailing ore pulp that floatingly selects carried out respectively press filtration, obtain zinc concentrate and zinc mine tailing; The zinc mine tailing of the cupric after press filtration entered for the 4th step, and filtrate is returned to cyanidation system;
The 4th step, select copper: the Tailings Slurry of the cupric that the 3rd step obtained is through press filtration, and sizes mixing to concentration 30-35%; First add sulfuric acid and transfer pH8.0-8.5, then add adjusting agent sodium carbonate 3kg/t ore deposit, carry out at last flotation, add collecting agent butyl xanthate 150g/t ore deposit,
Butylamine black powder 30g/t ore deposit; Concentrate slurry obtains copper concentrate through press filtration, and Tailings Slurry obtains the sulphur concentrate through press filtration.
Good effect of the present invention is:
At first the present invention utilizes each mineral that disinthibite of the cyanogen in system, reaches the purpose of separating flotation, rather than removes to destroy cyanogen, reaches without the cyanogen system and carries out flotation again; The 2nd,, realize that cyanide pulp just can select plumbous zinc without press filtration, this is the technique that prior art does not have; The 3rd,, select zinc not use copper sulphate to adopt raw ore slurry directly to add the sulfuric acid agent that adjusts, with the zinc that deactivates of the copper in system, this be domestic and international unique under Cyanide solution the regime of agent of activated zinc; The 4th,, the whole retrieval systems of the filtrate after flotation are not processed separately, have not only guaranteed the normal of cyanidation technology, have guaranteed the normal operation of floatation process yet, have saved simultaneously cost, and economic benefit is maximized.
The specific embodiment
Further illustrate the present invention below in conjunction with example.
Below that actual production process is given an example.
The first step, cyaniding: owing to being impure high Gold Concentrate under Normal Pressure, adopted the high concentration sodium cyanide solution, the concentration that ore pulp liquid contains Cyanide is the 0.70-0.75%(mass percent), pulp density is the 35-40%(mass percent), mog reaches 90-92% for-400 orders, and conventional zinc dust precipitation technique is adopted in the gold and silver displacement.And obtain cyaniding tailing slurry, enter second step.
Second step, choosing lead: cyaniding tailing slurry is after carrying out the three-tray thickener countercurrent washing, and ore pulp enters into and selects lead system by peristaltic pump.Pulp density is adjusted into 38-40%, and at first pH value 10-11 suppresses zinc with zinc sulfate and sodium carbonate, and consumption is respectively 1Kg/t ore deposit and 3kg/t ore deposit, then adds collecting agent butyl xanthate 80g/t ore deposit, diethyldithiocarbamate 80g/t ore deposit.After the lead concentrate ore pulp press filtration that floatingly selects, obtain lead concentrate and filtrate, lead concentrate is used for selling, and filtrate is returned to cyanidation system.Tailings Slurry after flotation entered into for the 3rd step.
The 3rd step, select zinc: select the Tailings Slurry after lead, first adjust with sulfuric acid, make pH9.0-9.5, the hydrogen cyanide that produces in process absorbs with alkali lye (sodium hydroxide solution), returns to use.Then add collecting agent butyl xanthate 200g/t ore deposit to carry out flotation, and zinc concentrate ore pulp and the mine tailing ore pulp that floatingly selects carried out respectively press filtration, obtain zinc concentrate and be used for selling, the Tailings Slurry of cupric entered for the 4th step, and filtrate is returned to cyanidation system.
The 4th step, select copper: the Tailings Slurry of the cupric that the 3rd step obtained is through press filtration, and sizes mixing with product liquid, and concentration is the 30-35%(mass percent).First add sulfuric acid and transfer pH8.0-8.5, then add adjusting agent sodium carbonate 3kg/t ore deposit, carry out at last flotation, add collecting agent butyl xanthate 150g/t ore deposit, butylamine black powder 30g/t ore deposit.Concentrate slurry obtains copper concentrate through press filtration and is used for selling, and Tailings Slurry obtains the sulphur concentrate through press filtration and is used for selling.
