Abstract
The invention relates to a technology of extracting and separating nickel-molybdenum from coal mines through high-pressure oxygen-ammonia immersion. Original ores are ground into powder and then immersed into hartshorn, and then oxygen is fed to cause reaction pressure to be between 1.5mPa-3.0mPa; after reaction and filtration, obtained base solution after ammonia distilling is dissolved by acid, and then organic phase containing molybdenum and water phase containing nickel acquired through extraction and separation are purified respectively. Compared with the prior art, the technology of the invention greatly reduces the environmental pollution, and improves the comprehensive utilization rate of mineral resources, with high recovery rate of valuable metals and high production purity. A semi-commercial experiment demonstrates that the recovery of the nickel-molybdenum all reaches above 90 percent.
Description
Technical field
The invention belongs to the hydrometallurgy field, relate to the method that molybdenum and nickel salt are extracted in a kind of molybdenum-nickel paragenetic ore deposit.
Background technology
Metal molybdenum and nickel are important non-ferrous metals, except mainly aspects such as metallurgical alloying steel are used, have widely-used in others such as chemical industry simultaneously.There are a lot of places all to find molybdenum ore in the world, Hui molybdenum ore, tungsten symbiosis and copper molybdenum symbiotic ore are arranged, but the rarely found nickel-molybdenum symbiotic ore of reporting.China has verified ground such as Hunan, Guizhou, Yunnan the sixties in last century and has contained a large amount of nickel-molybdenum symbiotic ores.Along with the scarcity of Mineral resources, rising steadily of this several years molybdenum nickel product prices particularly produced the comprehensive utilization of reasonable resources ground to nickel-molybdenum ore, can not only create profit for enterprise, and creates the wealth for country.
At present, domestic processing nickel-molybdenum ore production technique mainly is to take off charcoal through desulfurization with roasting technique, sodium carbonate roasting then, and water logging goes out, and reclaim molybdenum, and valuable metals such as ambrose alloy zinc remains in the leached mud, are utilized fully.This technology shortcoming is: 1. owing to produce a large amount of SO in the roasting process
2Gas causes environment to have a strong impact on; 2. the rate of recovery of molybdenum is low, has only about 80%; 3. nickel, copper, zinc resource are not fully used; 4. workman's severe operational environment.
Domestic the nickel-molybdenum symbiotic ore production method is started from the sixties in last century, mainly leach with conventional acid, alkaline process, the rate of recovery of molybdenum nickel is not high.Last century, some scientific worker of the nineties did more deep research to nickel-molybdenum ore.
Useful diluted acid leaches the research of nickel-molybdenum ore, as CN1267739A, uses 50% sulfuric acid, add 20% ammonium nitrate heating leaching, though the leaching yield height of this method molybdenum nickel, high-concentration sulfuric acid leaches, and will inevitably leach a large amount of impurity elements, as iron, aluminium etc., in order to obtain the single nickel salt product, must remove this part impurity, cause the loss of nickel, influence the total recovery of nickel element, and the single nickel salt product purity of producing is not high yet.
Useful diluted alkaline leaches the research of nickel-molybdenum ore, as CN1267740A, uses 50% ammoniacal liquor, adds 10% ammonium nitrate, is heated to 50 ℃～60 ℃ and leaches 3 hours.If do not adopt pressing mode, under normal pressure, be difficult to preparation 50% ammoniacal liquor, the utilization ratio of reheat ammonia is just lower.Its single nickel salt product also can only be thick product.
CN1177012A adopts first desulfurization with roasting technique to take off charcoal, uses 50% yellow soda ash in 700 ℃ of following slakings then, and the method that water logging goes out obtains the ammonium molybdate product, and this method not only contaminate environment is serious, and nickel is not accomplished Industrial products.
Summary of the invention
The objective of the invention is at nickel-molybdenum symbiotic ore, propose a kind of both environmental protection, the comprehensive utilization Mineral resources, the recovery rate of valuable metals height, the product purity height, good in economic efficiency, and also industrial truly feasible hyperbaric oxygen ammonia soaks the technology of extracting with the separating nickel molybdenum from the bone coal ore deposit.
The objective of the invention is to realize by following manner:
Technology of the present invention is: raw ore is clayed into power, be immersed in the ammonia soln, aerating oxygen makes reaction pressure at 1.5mPa～3.0mPa, the reaction after-filtration, the later end liquid of ammonia still process dissolves with acid, obtains containing the organic phase of molybdenum then by extracting and separating, nickeliferous water is until the difference purifying.
The liquid-solid ratio volume ratio of described ammoniacal liquor and breeze is 1.5～5, ammoniacal liquor mass concentration 10%～20%,
60 ℃～200 ℃ of described temperature of reaction, preferred 4 hours～10 hours of reaction times.
Liquid sulfuric acid dissolution of the described end, dissolved pH is 1～3.
Described extraction agent preferred mass concentration is with 10%～20% 3 aliphatic amide.
The described organic phase purge process that contains molybdenum is: washing collection molybdenum saturated organic phase with mass concentration 10%～20% ammoniacal liquor reextraction molybdenum, obtains ammonium molybdate solution.
Heavy or condensing crystal obtains ammonium molybdate by acid with ammonium molybdate solution.Further calcining then obtains molybdenum oxide.
Described nickeliferous water purge process is: collection molybdenum water is 3～5 usefulness mass concentrations, 10%～20% metal extraction agent (P204) extracting copper zinc in pH, washing nickel.
Nickeliferous water after the removal of impurities is that 4～6 collection nickel remove sodium through mass concentration 10%～20% metal extraction agent (P204) in pH again, and sulfuric acid reextraction nickel obtains the high-purity sulphuric acid nickel solution, obtains industrial one-level single nickel salt product through crystallization.
With sulfuric acid reextraction copper zinc, obtain copper sulfate zinc byproduct.
The present invention has obtained the checking of test and suitability for industrialized production, and it possesses following characteristics: 1. owing to there is not to produce in the roasting process a large amount of SO
2Gas greatly reduces the pollution to environment, has improved workman's operating environment; 2. the total yield height of molybdenum nickel can reach more than 90%.3. the resulting molybdenum of technology of the present invention, nickel product purity height can both reach the technical grade product requirement.
In addition, the present invention also reclaims molybdenum, nickel, copper, zinc simultaneously effectively, makes valuable resource be fully used.
