Abstract
The invention relates to a method for purifying defective gallium produced by a resin adsorption method, which is characterized in that: crystallization purification is performed by a metal remelting crystallization method in the treatment process. Compared with the prior art, the method for purifying the defective gallium produced by the resin adsorption method is easy to operate and practicable, effectively reduces cost, effectively solves the problem of the defective gallium, and increases the yield of gallium.
Description
Technical field
The present invention relates to a kind of method of purification of substandard products gallium of resin adsorption method production.
Background technology
In the gallium production process, occurring substandard products once in a while can not avoid.Substandard products generally are to produce in the gallium technology at resin adsorption method not remove thoroughly except that heavy link lead, copper, and lead, copper exceed standard in the finished product thereby cause.Treatment process is to utilize the true tube furnace of open type to purify at present, the method of purification process is that the substandard products gallium is put into stove, in vacuum environment, be heated to about 2400 ℃, make gallium volatilization the becoming gaseous state in the solid-state substandard products gallium, extract the gaseous state gallium out again with its condensation, again become solid-stately or liquid, reach the purpose of purification with the physical property of utilizing the gallium boiling point.Can see that from above technological process its energy consumption is very high, and consuming time very long, and the expense costliness increases the gallium production cost.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, the method for purification of the substandard products gallium that the resin adsorption method that provide a kind of and effectively cut down the consumption of energy, reduces production costs, refining effect is good is produced.
The objective of the invention is to be achieved through the following technical solutions.
The method of purification of the substandard products gallium that a kind of resin adsorption method is produced is characterized in that its treating processes adopts metal remelting crystalline method to carry out crystallization and purification.
The method of purification of the substandard products gallium that a kind of resin adsorption method of the present invention is produced is characterized in that the step of purification process comprises:
1) the substandard products gallium is dissolved 35 ℃-40 ℃ temperature;
2) gallium after will dissolving is freezing in-5 ℃-0 ℃ refrigerator-freezer, placed 1 hour, take out xln, to be crystallized getting after rolling, be reentered into refrigerator-freezer freezing 1 hour, and took out container again, continue to get xln, xln weight to be removed is two of gross weight/for the moment, with the substandard products gallium of remainder again at 35 ℃--dissolve under 40 ℃ of temperature;
3) operation of repeating step (2), taking out total amount to crystallization is 95% of substandard products gallium, is the gallium after purifying.
The method of purification of the substandard products gallium that a kind of resin adsorption method of the present invention is produced, the taking-up amount that it is characterized in that xln is 95% of a substandard products total amount
The method of purification of the substandard products gallium that a kind of resin adsorption method of the present invention is produced, compared with prior art operation is simple, reduced cost effectively, efficiently solves substandard products gallium problem, increased the yield rate of gallium.
