Description
Technical field
The present invention relates to technical field of rare-earth separation, the especially a kind of special precipitating reagent of ionic minerals separation factory and its system
Preparation Method.
Background technology
China is the maximum rare earth resources big country in the whole world, and in explored resource, China rare earth reserves account for about the whole world
The 31% of total amount.The addition of rare earth can improve the quality and performance of other products, be widely used in each of modern society
The various high-technology fields such as field, including hybrid vehicle, mobile phone, superconductor and military affairs, thus have " 21 century Huang
The good reputation of gold ".Especially prominent, rare earth can greatly improve the combat performance of related modern military new and high technology weapon, be
A kind of very important strategic resource.
The big series of rare earth main component in China accounts for China's rare earth first, with the light rare earth resource that light rare earth is main partition
The 88% of industrial gross reserves is mainly distributed on one band of Inner Mongol Bayan Obo and Mianning, sichuan Province, mainly has lanthanum, cerium, praseodymium, neodymium and lacks
Measure samarium and europium etc.;Wherein typical mineral is packet header Bastnaesite-Monazite mixed rare earth concentrate, and such mineral deposits account for generation
The 25% of boundary's reserves is the first in the world.Second is that in, heavy rare earth be main partition in, heavy ion type rare earth resources, with rare
The ionic condition preservation seen in clay class mineral, integrated distribution on Jiangxi, Guangdong, Hunan, Fujian and other places, rich in samarium, europium,
Gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, yttrium etc., value are very high.
Ion type rareearth ore is the exclusive extremely important mineral resources again in China, europium that ion type rareearth mineral deposit is rich in,
Terbium, dysprosium are to be difficult to obtain, added value high middle heavy rare earth element again from other Rare Earth Mines.Southern ion type rareearth ore exploit to
The present has more than 40 years history, since ion type rareearth mineral rare earth element mainly mutually exists with ion, using traditional object
Reason beneficiating method cannot be such that rare-earth original ore is enriched with, and be unable to get corresponding rare earth ore concentrate, can only use the beneficiating method of Chemical Leaching, carry
The technological process taken includes Situ Leaching, leachate removal of impurities, extracts mixed rare earth compound from leachate, manufactured various mixed
Rare earth compound such as mixed rare earth chlorides are closed, product, or the further raw material for being separated into single rare earth can be used as.
Wherein, by obtained mixed rare earth compound after Rare Earth Concentrate Decomposition, separating and extracting single pure rare earth element, in chemistry
It is more complicated and difficult in technique.Use at present it is more be solvent extraction, be using organic solvent from its
Different rare earth elements is extracted respectively in not miscible aqueous solution, single earth solution is obtained, then distinguishes again
Carry out precipitation separation.Obtained single earth solution, it is usually anti-with earth solution using ammonium bicarbonate soln as precipitating reagent
It answers, after the completion of reaction, slurries can obtain the positive carbonate of rare earth after being filtered, washed, and this technique can introduce NH using ammonium hydrogen carbonate4 +
Ion causes ammonia nitrogen in waste water exceeded, and harmful effect is generated to the environment of surrounding.
The patent of invention that Authorization Notice No. is CN105803199 discloses a kind of hydroxide precipitation method and prepares low-sulfur rare earth
The method of oxide is added containing the dissolved organic matters such as malic acid, acetylacetone,2,4-pentanedione, mixed configuration in rare earth sulfate solution
At precipitation stoste;Alkaline precipitating agent is added into precipitation stoste again and carries out precipitation reaction, the dosage of the precipitating reagent is precipitation institute
The 105%~120% of the theoretical amount of the rare earth in rare earth sulfate solution is stated, wherein alkaline precipitating agent includes ammonium hydroxide, hydroxide
One or more of sodium, calcium hydroxide, magnesium hydroxide, calcium oxide and magnesia.This method can obtain low-sulfur rare-earth oxidation
Object, but it has been still incorporated into a large amount of NH according to ammonium hydroxide4 +Ion can not fundamentally solve the problems, such as that ammonia nitrogen is exceeded, if adopting
With other hydroxide or oxide, still it is used as precipitating reagent by artificial synthesized chemical reagent with simple, precipitates
It is of high cost.
To solve the problems, such as ecological disruption, the special precipitating reagent of separation factory for reducing ammonia and nitrogen pollution is extremely important by a kind of exploitation
's.
