Abstract
Extraction of nickel oxide from serpentine with low content of nickel oxide by sulfuric acid leaching out process is carried out by hot leaching at pressure, treating the leaching liquid with solid settling agent to obtain nickel containing sediment with grade of 20-50% nickel content. It is of less investment, easy operation safely and without toxicity, less cost and high yield, and can be widely used to treat other nickel ores with low grade.
Description
The present invention relates to the extraction of extraction metallurgy, the especially nickel element of non-ferrous metal.
The extraction master of nickel adopts flotation from nickel sulfide ore at present, and the nickel grade that sorts out generally between 3%～8%, adopts pyrometallurgical smelting to become low nickel matte (nickeliferous 10～20%) or high ice nickel (nickeliferous 30～50%) then.For the serpentine that contains low-grade nickel oxide adopt roasting-ammonia to soak or reduce more-pickling process reclaims the nickel metal.(" non-ferrous extractive metallurgy handbook (copper nickel volume) ", metallurgical press, 2000 of adopting sulfuric acid process to extract are also arranged, 7, first version, P724～727), but its method that adopts is high temperature (249 ℃) high pressure (3.4Mpa) to be leached, and leach liquor is heated to pressurize with hydrogen sulfide and reclaimed the nickel metal.The disposable worker of this method throws higher, needs to build the reactor of high temperature high voltage resistant, huge boiler.To produce the hydrogen sulfide of coprecipitated nickel hydroxide metal in the recovery after leaching the nickel metal, and the pressurization of when precipitation, also will heating, not only investment is high, and technical process is also complicated, and the output cost is also high.
Purpose of the present invention is exactly high in order to overcome present nickel oxide sulfuric acid leaching investment, the technical process complexity, and the deficiency that the output cost is high provides a kind of less investment, the simple low-cost nickel oxide sulfuric acid leaching of Technology.Another object of the present invention is that low-grade nickel oxide (about 1%) in the serpentine is extracted, and this precious resources is utilized.
The present invention is milled to 0.074mm～2mm with serpentine, makes serpentine concentration and be 20～50% ore pulp, adds the vitriol oil under stirring state, its amount is 15%～50% of serpentine amount, controlled temperature is 60 ℃～90 ℃, and normal pressure leached 1～5 hour, and leaching terminal point pH is 1～3.Natural subsidence is isolated leach liquor then.Add precipitation agent to leach liquor, precipitation agent can be chosen any one kind of them from sodium sulphite, sodium hydroxide and yellow soda ash, and nickel ion is precipitated out, and thickening filtration is the nickel ore concentrate product.
If to the precipitation agent sodium sulphite that leach liquor adds, add-on is 2～5 times of nickel amount of metal, if sodium hydroxide, add-on is 1～4 times of nickel amount of metal, if yellow soda ash, add-on is 1～4 times of nickel amount of metal.
Preferred plan of the present invention is for to be crushed to serpentine about granularity 1mm, makes concentration and be 30% ore pulp, adds the vitriol oil of serpentine amount 20%, leach in heating with under stirring, controlled temperature is about 80 ℃, and leach liquor pH is 2～3 when leaching terminal point, about 3 hours of extraction time.Natural subsidence is isolated leach liquor then.Add 3 times of precipitation agents of measuring the nickel metals to leach liquor, precipitation agent can be chosen any one kind of them from sodium sulphite, sodium hydroxide and yellow soda ash, and nickel ion is precipitated out, and thickening filtration promptly gets the nickel ore concentrate product.
The present invention only needs to operate under normal pressure, and processing temperature is below 100 ℃, because the vitriol oil and ore pulp have a large amount of thermogenesis as the time spent, thus only need heating a little just can reach temperature required, thereby facility investment is few, temperature is controlled easily, safety simple to operate.Adopt solid sodium sulfide normal temperature and pressure coprecipitated nickel hydroxide metal, pressurization in the time of need not making the equipment of hydrogen sulfide and hydrogen sulfide coprecipitated nickel hydroxide metal, warming-up device, also saved the latent sorrow of operating the worried of toxic gas hydrogen sulfide and causing environmental pollution, common settling tank just can satisfy the production needs, and the nickel ore concentrate grade that is settled out is up to 20～50%, nickel ore concentrate (3～8%) than flotation is much higher, and cost is comparatively cheap, 40,000 yuan of the nickel ore concentrate ton cost less thaies that present method is produced, market price is about 4.5～50,000 yuan.Compare with the sulfuric acid leaching of present nickel oxide, less investment of the present invention, technology is simple, and operational safety is nontoxic, and the nickel ore concentrate of output is not only of high grade, and cost is low, and is very competitive.The present invention be advantageous in that and to extract low-grade nickel oxide (about 1%), be not only applicable to the extraction of nickel oxide in the serpentine, and be applicable to from other contains the ore of low-grade nickel oxide and extract nickel.
