Domain.
Background technology
Rare earth is universally acknowledged developing high-tech, national defence sophisticated technology, indispensable strategy of rebuilding traditional industry
Resource.Ion type rareearth ore have it is light, in, heavy rare earth partition it is complete, rich in close with high-tech, high tip, new material industry
In related, heavy rare earth element, utilization ion type rareearth ore occupies great strategic position in China's economic development.
The leaching process of ion type rareearth ore is successively selected using sodium chloride and ammonium sulfate as leaching agent, the leaching of ammonium sulfate
Selecting property is substantially better than sodium chloride, is advantageous to the extraction of leaching liquid Rare Earth Ion, is the main leaching agent that current rare earth leaches.But
It is that ammonium sulfate leaching agent can bring substantial amounts of ammonia nitrogen waste water, to produce 3000 tons of rare earth per year（REO is counted）, caused wastewater treatment capacity
About 1,800,000 tons/year, about 6000 tons/year of ammonia nitrogen discharge capacity, and pollution control cost is high；In addition, when ammonium sulfate leaches rare earth, leaching
It is big to go out agent consumption, causes the wasting of resources.Therefore, developing green, efficient leaching process reduces ammonia nitrogen waste water pollution, realizes economic ring
Sustainable development of the Extraction of rare eart of guarantor to China's rare-earth industry has far-reaching significance.
In recent years, outfield intensifying leaching-out technique（Ultrasonic wave）It has been increasingly being applied to metallurgical industry, such as gold, silver, copper
The Strengthen education of ore deposit, the microjet for being produced strong impact and high speed to reaction-ure surface using the cavitation effect of ultrasonic wave are rushed
Erosion so that the chemical reaction under ultrasound field is easily carried out, and reaches the process of Strengthen education, has certain development prospect.
The content of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of outfield intensifying without ammonia leached ions type
The method of Rare Earth Mine.The present invention reduces the generation of ammonia nitrogen waste water while high rare earth leaching rate is ensured, be a kind of green,
Economic new technology, the present invention are achieved through the following technical solutions.
A kind of method of outfield intensifying without ammonia leached ions type Rare Earth Mine, it is comprised the following steps that：By ion type rareearth ore
It is 1 according to liquid-solid ratio:1~20:1ml/g adds concentration and leaches agent solution without ammonia salt for 1wt%~10wt%, in room temperature ultrasonic
In the presence of 10~180min of leaching, leach and through solid-liquor separation obtain leachate after completing, wherein being without ammonia salt leaching agent
The mixture of calcium chloride or calcium chloride and any ratio of magnesium sulfate.
The ion type rareearth ore refers to that rare earth adsorbs the south on clay mineral with hydrated ion or hydroxyl hydrated ion
Square ion type rareearth ore.
The power of the ultrasonic wave is more than 100W.
The beneficial effects of the invention are as follows：（1）The present invention uses no ammonia leaching agent as raw material, fundamentally solves ammonia nitrogen dirt
The technical barrier of dye, meet the industrial policy of national development rare-earth trade.（2）The present invention uses the leaching of intensified by ultrasonic wave rare earth
Go out, the technology has the advantages that simple to operate, pollution-free while leaching rate is greatly improved.（3）Pass through the method for the present invention
Rare earth leaching rate can reach 99.62%, and rare earth leaching rate 72.55% when ammonium sulfate leaches, and improve 37.31%.
