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 heap in the process of seepage flow, optionally dissolve and leach useful constituent in ore or the barren rock, make it to change in the leaching solution, in order 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.
Dump leaching is put forward uranium technique and is had the outstanding advantages such as technique is simple, cost is low, has become the main process that China's natural uranium is produced.When 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 so that composing, most of uranium mineral has the 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 also is package status, is not communicated with the external world, causes leaching solution to contact with it, thereby can't 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.
Both domestic and externally studies show that in a large number, microwave irradiation is to increasing the crack of 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 there is very big-difference in the performance of different mineral absorption microwave, thereby when utilizing microwave irradiation that it is heated, can present different firing rates.The performance that pitch blende in the uranium ore, brannerite, troilite, sulphur molybdenum ore etc. absorb microwave energy is strong, and its firing rate is fast, often up to tens degrees centigrade of per seconds; And gangue wherein then can not absorb microwave energy such as quartz, calcite, dolomite, barite etc., and its firing rate only is several centigrade per minutes.Owing to having temperature gradient between the different minerals, cause the 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, the 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, drying, sterilization and the field such as fresh-keeping.And it is present only for the microwave heating carbon thermal reduction of burning mineral, the microwave heating leaching of sulphide ore, the microwave oxidation dearsenification of niccolite etc. in the mining and metallurgy field.When adopting these traditional microwave equipments that the dump leaching ore is processed, exist the microwave power coupling poor, the 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 just be difficult to improve leaching rate, the shortening leaching cycle of dump leaching.Therefore, need research and develop to process 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.
