Description
Technical field
The present invention relates to the cyanogen slag harmlessness of gold industry field of environment protection processing aspects, more particularly to gold ore cyanogen
Change tailings and backfills the harmless treatment utilized.
Background technique
Cyanogen slag is the solid waste that gold-bearing material generates after Cyanide Leaching, separation of solid and liquid, including gold ore cyanidation tailings,
Refined gold ore cyaniding tailings, dump leaching cyanidation tailings.Cyanogen slag is not because containing hypertoxic cyanide, therefore, country allows using cyanogen slag before
Carry out backfill utilization.
On March 1st, 2018 " gold industry cyanogen slag pollution control technology specification " HJ943-2018 (hereinafter referred to as " cyanogen slag rule
Model ") after publication implemented, gold ore cyanidation tailings harmless treatment in cyanogen slag meets " cyanogen slag specification " and backfills pollution control technology
After it is required that, backfill utilization can be carried out.So far, the gold ore cyanidation tailings in cyanogen slag backfill pollution control in satisfaction " cyanogen slag specification "
After technical requirements processed, underground filling utilization can be carried out.Gold ore cyanidation tailings are with gold ore or warp without sorting operation
The tailing of sorting operation gold ore is raw material, the cyanogen slag after comminution, pretreatment, after gold is extracted using Cyanide Leaching.
Before " cyanogen slag specification " publication, backfill cyanogen slag it is innoxious on, although carrying out some exploratory technical research,
Since country does not have relevant criterion, can not develop feasible harmless treatment process technology therefore in the backfill of cyanogen slag becomes
Problem in the backfill utilization of gold ore cyanidation tailings.
Summary of the invention
The present invention provides a kind of method for innocent treatment utilized for the backfill of gold ore cyanidation tailings, to solve gold ore
Cyanidation tailings backfill utilizes the problem without feasible innoxious process for treating,
The technical solution adopted by the present invention is that: include the following steps:
(1) gold ore cyaniding tailing slurry carries out decyanation processing using " being separated by solid-liquid separation secondary washing ":
1) squeeze: the efficient filter press that gold ore cyaniding tailing slurry uses band " to air-dry, backwash " function carries out squeezing operation,
Blowback is carried out using pressure air after squeezing, is air-dried, pressing filtrate and blowback liquid return to cyanide circuit；
2) once washing: filter residue carries out once washing with water or secondary washing liquid in filter press, and pressure is used after washing
Air carries out blowback, air-dries, and once washing liquid and once washing blowback liquid return to cyanide circuit；
3) secondary washing: the filter residue after once washing carries out secondary washing with water in filter press, after washing carry out blowback,
It air-dries, secondary washing liquid and secondary washing blowback liquid can be used as the once washing water of lower subjob；
(2) ozone Oxidation Treatment:
1) size mixing: secondary washing filter residue is added in surge tank in filter press, and water or ozone treatment filtrate is added to be stirred
It sizes mixing；
2) ozone oxidation: the ore pulp modulated in surge tank is sent into ozone reactor, is passed through ozone generator generation
Ozone gas carries out the processing of ozone deep oxidation；
3) squeeze: the ore pulp after ozone treatment carries out squeezing work using the efficient filter press that band " air-dries, backwash " function
Industry carries out blowback using pressure air after squeezing, air-dries, and the ozone treatment liquid squeezed out and blowback go out ozone treatment liquid and can make
Water of sizing mixing for second wash water and secondary washing filter residue uses.
The invention also includes: underground filling is carried out using the filter residue after harmless treatment as aggregate.
After " cyanogen slag specification " publication, Co., Ltd, Changchun Gold Research Institute utilizes the backfill of gold ore cyanidation tailings harmless
Change processing technique to be developed, successfully develops gold ore cyanidation tailings backfill pollution control technology in satisfaction " cyanogen slag specification " and want
" the be separated by solid-liquid separation secondary washing size mixing+ozone oxidation " technology asked solves the backfill of gold ore cyanidation tailings using can not
The problem of row innoxious process for treating can be used as filling aggregate after so that gold ore cyanidation tailings is used the technology harmless treatment
It is utilized by underground filling.Economically, the expenses such as buying and the transport of filling aggregate can be saved, tail can be saved or reduce
The expropriation of land of mine library, construction cost and daily maintenance expense, can effectively recycle solubilized gold, silver and cyanogen remaining in lean solution contained by cyanogen slag
The valuable components such as compound；In the environment, cyanogen slag existing environmental risk in terms of transport, storage and Tailings Dam disposition can be reduced.
" innoxious " and " recycling " for accomplishing cyanogen slag solves the backfill of cyanogen slag and utilizes innoxious technical problem.Particularly with can not
The all sliming cyanidation manufacturing enterprise of newly-built Tailings Dam, provides the new way that a cyanogen slag utilizes.Therefore, there is the backfill of cyanogen slag for similar
Demand mine, the Technique Popularizing have a extensive future.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
Include the following steps:
(1) gold ore cyaniding tailing slurry carries out decyanation processing using " being separated by solid-liquid separation secondary washing ":
