Description
Technical field
The present invention relates to dump leaching uranium ore microwave processing equipment, be specifically related to a kind of degree of dissociation of utilizing the intragranular porosity of microwave irradiation increase uranium ore, improving the intragranular permeability of uranium ore, raising uranium mineral, thus the dump leaching uranium ore microwave processing equipment of raising Heap Leaching of Uranium Ore leaching rate, shortening leaching cycle.
Background technology
Dump leaching is that leaching solution is sprayed on ore or hillock, at it in the process of seepage flow in heap, optionally dissolve and leach the useful constituent in ore or barren rock, making it to proceed in leaching solution, to further extract or reclaim a kind of method of this useful constituent.At present, dump leaching is that China processes the materials such as lean ore, mine tailing, ettle on a large scale, extracts a kind of effective and economic method of uranium, copper, gold and the metal such as silver-colored.
Heap lixiviate uranium technique has the outstanding advantages such as technique is simple, cost is low, has become the main process that China's natural uranium is produced.While implementing dump leaching, in order to guarantee the permeability of dump leaching uranium ore heap, must guarantee that uranium ore has enough large granularity, so just make most of uranium mineral compose and have uranium ore granule interior, the chemical reaction of leaching solution and dump leaching uranium ore and the migration of uranium metal can only be undertaken by the intragranular hole of uranium ore, cause the leaching cycle of dump leaching process long.Some uranium mineral is also package status, is not communicated with the external world, causes leaching solution to contact with it, thereby cannot leach, and causes the leaching rate of dump leaching process low.Therefore, increasing the crack of uranium ore granule interior, improve the permeability of uranium ore granule interior, leaching solution can fully be contacted with the intragranular uranium mineral of uranium ore, is the fundamental way that improves heap leaching rate, shortens leaching cycle.
Large quantity research both domestic and external shows, the crack of microwave irradiation to increase ore particles inside, and the permeability of improving ore particles inside has significant effect.Microwave irradiation is present to the acting body of uranium ore: because the performance of different mineral absorption microwaves exists very big-difference, thereby while utilizing microwave irradiation to heat it, can present different firing rates.The performance that pitch blende in uranium ore, brannerite, troilite, sulphur molybdenum ore etc. absorb microwave energy is strong, and its firing rate is fast, often per second up to tens degrees Celsius; And gangue wherein, as quartz, calcite, dolomite, barite etc. can not absorb microwave energy, its firing rate is only several centigrade per minutes.Owing to there being temperature gradient between different minerals, cause uranium ore granule interior to produce larger thermal stress poor, the thermal coefficient of expansion that adds various mineral there are differences, cause the inner generation of ore particles intercrystalline cracking, preexisting crack expansion, thereby increased ore particles inside porosity, improve the permeability of ore particles inside, this can further improve Heap Leaching of Uranium Ore leaching rate, shorten leaching cycle.
At present, industrial microwave apparatus has been widely used in food, chemical industry, medicine, agricultural byproducts processing, dry, sterilization and the field such as fresh-keeping.And in mining and metallurgy field at present only for the microwave heating carbon thermal reduction of burning mineral, the microwave of the microwave heating leaching of sulphide ore, niccolite oxidation dearsenification etc.While adopting these traditional microwave equipments to process dump leaching ore, exist microwave power coupling poor, microwave reflection coupling is large, the shortcomings such as the thermal effect that produces with ore is low, be difficult to increase the porosity of ore particles inside, be difficult to improve the permeability of uranium ore granule interior, also be just difficult to improve leaching rate, the shortening leaching cycle of dump leaching.Therefore, need research and develop for processing the industrial microwave apparatus of dump leaching ore, especially need be for the microwave irradiation characteristic of dump leaching uranium ore, the dump leaching uranium ore microwave processing equipment of development commercial production scale.
