Abstract
The invention opened a recovery method for the polymetallic bullion ore of high sulphur, carbon and arsenic. It solves the problem of extracting gold interfering by the sulphur and carbon. The chlorination extracting system is proper not only to sulfide mineral but also to the polymetallic accompanying mineral. Also it can recovery the accompanying metal less than 8h, so it has improved the extracting ratio. The process is easy to do and low cost.
Description
Technical field
The present invention relates to a kind of pretreatment technology, extract technology and many metals comprehensive recycling process, especially, obtain gold and silver and many metals respectively by flow process by low temperature chlorine sulphur oxidation pre-treatment at high-sulfur, high-carbon or high arsenic type bullion ore with various metals.
Background technology
Existing kustelite preconditioning technique has: oxidizing roasting: carry out air roasting and oxygen-enriched air roasting usually under 600 ℃～900 ℃ condition, the oxidizing roasting method is the pretreatment process of using the earliest, technical maturity, with a high credibility, but adaptability is limited by deposit type or metallogenic material, sometimes the associated metal rate of recovery is low, especially silver.Gu the solid arsenic roasting of sulphur: can add yellow soda ash, calcium oxide or calcium hydroxide and mix the back roasting with sample ore, sulphur and arsenic are converted into vitriol and arsenate is fixed in the calcining, and the sample ore that this method processing sulphur and arsenic content are not high is passable, as sulphur and arsenic content height, can pollute environment, also uneconomical.Two-section roasting is handled high-Arsen gold ore: this method causes burning easily, makes the leaching yield of gold on the low side.Pressure oxidation: being that pressurization is leached under the high temperature aerobic conditions, is that vitriol dissociates gold with sulfide oxidation, is convenient to next step leaching, and this method facility investment is big, the production cost height.Biological oxidation process: the bacterial oxidation of sulphide ores and concentrate, mainly utilize thiobacillus ferrooxidant, destroy the sulfide lattice, this method subject matter is that oxidation cycle is long, and speed is slow, and temperature control is strict.
Existing extract technology has; Cyanide process: cyanidation gold-extracted is the method that generally adopts both at home and abroad, and technical maturity, adaptability are strong, but its prussiate severe toxicity is detrimental to health, and causes environmental pollution, and it is slow to soak golden speed, and selectivity is relatively poor, and is not high to the leaching yield of silver.The thiocarbamide method: France extracted gold in 1977 in the zinc fritted sand, though its nontoxic, easy circulation, to soak golden speed fast, thiocarbamide consumption is big, and the price height soaks gold and will carry out in acidic solution, and equipment is corrosive, and operational condition is relatively stricter.Thiosulfate technique: though speed is fast, nontoxic, the consumption height is difficult to recycle, and the operational condition harshness is difficult to industrialization.The polysulfide method: though selectivity is good, nontoxic, leaching velocity is fast, poor heat stability because the effusion of hydrogen sulfide and ammonia has worsened labor condition, is difficult to use.Microbial method: though it is low to soak golden cost, non-environmental-pollution, leaching velocity are too slow.Water chlorination process; Biggest advantage is that leaching velocity is fast, and the leaching yield height owing to use the chlorine production environment poor, though many scientists have done some improvement, but does not tackle the problem at its root.
CN90103384.7 disclosed " Cl-carrier chlorination process for extracting Au and silver " is though solved cyanogen, mercury pollution problem, but be not suitable for the bullion ore with various metals that contains of high-carbon, high-sulfur, high arsenic, soaking gold will carry out in strongly acidic solution, equipment there is corrosion, and extraction time is grown (24 hours), and efficient is on the low side.
AU8425022A, US4662938, GB2154221A, the disclosed technology of CN87103312A is all different with recovery method of the present invention, and can not solve the comprehensive recovery of high-sulfur, high-carbon, high arsenic type bullion ore with various metals.
Summary of the invention
Purpose of the present invention just is at above-mentioned the deficiencies in the prior art, and a kind of high-carbon, high-sulfur, high arsenic type comprehensive recovery for bullion ore with various metals of being applicable to is provided, and substitutes the method for existing cyanide gold-leaching, silver.
The objective of the invention is to realize in the following manner:
A, get many metallic gold silver preparation concentrate powder and add 5～20% solid sodium chlorides by weight, send into the continous way rotary kiln after the mixing and heat 300-450 ℃, and pre-treatment was finished in insulation in 3.5-4 hour;
B, with pretreated breeze in solid-liquid 1: 4-1: 6 ratio is immersed in the sodium chloride solution that concentration is 11%～15% hypochlorous acid and 5-25%, press calcining weight and add cyanuric acid 7-15kg/ ton, stir 6～8 hours after filtration washing forms your liquid and filter residue, filter residue enters the mine tailing storehouse;
The expensive liquid of c passes through the C410 resin-column with the flow velocity less than 100mL/ minute, thereby gold and silver and many metals are separated, and forms to carry the gold and silver resin and contain liquid under many metal columns;
D, the thiocarbamide wash-out with 3% carry the gold and silver resin, formation contains gold and silver liquid, elutriant is 30: 1 with the volume ratio of carrying the gold and silver resin, adds NaOH in containing gold and silver liquid, transfers pH=11, make gold and silver form precipitation of hydroxide, washing after filtration, it is molten to transparent to add 1: 1 chloroazotic acid in containing the gold and silver throw out, adds sodium-chlor to the black silver nitride precipitation, Jin Yuyin is separated, in gold-containing solution, add gold content 2-3 solid Fe doubly
2SO
4, making the gold reduction, precipitation washing back oven dry after filtration promptly gets bronze;
With iron powder reducing, the iron powder consumption is 1.5～2.0 times of silver-colored theory of reduction amount in the weak hydrochloric acid soln of pH=1 for e, silver nitride precipitation, and sedimentation and filtration washing back oven dry promptly gets silver powder.
F, under containing polymetallic post, add NaOH in the liquid, transfer pH=3, make the iron precipitation, obtain poly-ferric chloride after filtering;
Add zinc dust precipitation copper behind g, the heavy iron, the zinc powder add-on be the twice of theoretical displacement copper amount, gets copper sponge after filtration after the washing;
To add concentration be 20% sodium sulfate to solution to regeneration lead sulfate precipitation not behind h, the heavy copper, obtains lead sulfate behind the filtration washing;
Solution behind i, the heavy lead adds NaOH and transfers pH=6～7, gets the zinc hydroxide precipitation.
Positively effect of the present invention:
Comprehensive recovery for bullion ore with various metals of the present invention has solved the problem of the pre-treatment difficulty of high-carbon, high-sulfur or high arsenic minerals, and can reclaim the associated metal in the kustelite easily; The water chlorination process that adopts hypochlorous acid to add tricarbimide in the solution of sodium-chlor leaches nontoxic, have intensive and leach ability, strong to adaptability of mineral, be not only applicable to the single mineral of sulfide and be applicable to many metals of sulfide associated minerals yet, carry out gold and silver and polymetallic leaching at normal temperatures, and leaching velocity is fast, extraction time is no more than 8 hours, improve the leaching yield of gold and silver effectively, have economic benefit and environmental benefit significantly.
