Abstract
The invention provides a kind of cyanogen-containing tailing innoxious paste body filling method, comprise the following steps: after deep cone concentrates, size mixing, two-stage nitration bores concentrations deeply, secondary is sized mixing, except cyanogen oxidation and concentration.Cyanogen-containing tailing provided by the present invention innoxious paste body filling method, the method using physics sedimentation and dilution desorption technique, chemical oxidation techniques and paste body filling technology to combine, comprehensively utilize again after sludge containing cyanogens is carried out harmless treatment.This method technological process is simple, and treatment effeciency is high, and operating cost is low, relieves the security context hidden danger of cyanogen-containing tailing.
Description
Technical field
The invention belongs to tailings glass field, be specifically related to a kind of cyanogen-containing tailing innoxious paste body filling method.
Background technology
Cyanidation gold-extracted being still current gold manufacturing enterprises and carry the prevailing technology of gold, but this technique can produce in process of production
Substantial amounts of containing cyanogen waste residue.The expansion along with golden production scale and production history is processed at present containing cyanogen waste residue many employings bin system
Prolongation, gold tailings accumulating amount increases year by year and does not only take up a large amount of soil, polluted surface water, subsoil water and soil, and very
Many Tailings Dams exceed the time limit or over loading uses, and make Tailings Dam there is very big potential safety hazard, and once break down leakage, it will the ring to surrounding
Border produces great pollution effect, and Tailings Dam is built and maintenance management also needs to put into substantial contribution simultaneously.Therefore, accelerate to advance Huang
Gold is smelted containing cyanogen Solid state fermentation and comprehensive utilization extremely urgent.
The harmless treatment approach of sludge containing cyanogens has two classes, a class to be to Tailings Slurry filter pressing, the dry heap of filtering residue, and filtrate is carried out
Integrated treatment, reuse or qualified discharge after process;Another kind of is that Tailings Slurry directly processes, and method is substantially destruction cyanide.Before
Person is easily processed due to mud-water separation, cyanide, technology maturation, controls simple, but owing to filter pressing cost is high, it is difficult at large ore
Mountain popularization and application.The development trend of gold industry is to develop towards extensive treating capacity, and corresponding, sludge containing cyanogens is harmless
The development trend that change processes is towards the direction progress directly processed.
Summary of the invention
In order to solve above technical problem, the invention provides a kind of cyanogen-containing tailing innoxious paste body filling method, including
Following steps:
(1) mine tailing ore pulp is after one section of deep cone concentrates, and supernatant fluid reuse, underflow adds new water under stirring and adjusts
Slurry;
(2) ore pulp after sizing mixing is after two-stage nitration bores concentration deeply, and supernatant fluid reuse, underflow adds new water under stirring and enters
Row secondary is sized mixing;
(3) after secondary is sized mixing, ore pulp control ph is in the range of 8~9, adds except cyanogen oxidant, reaction under stirring
30min~50min;
(4) concentrate except the ore pulp after cyanogen oxidation processes enters mastic thickener, make mass concentration 68%~70%
Mastic, mastic is used for mine down-hole filling.
2., in step described in (1), (2), deep cone concentrates end mass concentration flow control 55%~60%.
3., in step described in (3), after secondary is sized mixing, ore pulp mass concentration controls 39%~42%, addition except cyanogen aoxidize
Agent is calcium hypochlorite, and calcium hypochlorite dosage is relevant with ore pulp cyanide content, the calcium hypochlorite that cyanide content height then adds
Many, cyanide content is low, and the calcium hypochlorite added is few.
The invention provides a kind of cyanogen-containing tailing innoxious paste body filling method, use physics sedimentation and dilution desorbing skill
The method that art, chemical oxidation techniques and paste body filling technology combine, the most comprehensive after sludge containing cyanogens is carried out harmless treatment
Utilize.This method technological process is simple, and treatment effeciency is high, and operating cost is low, relieves the security context hidden danger of cyanogen-containing tailing.
