Description

Germanic organic matter produces germanium tetrachloride new process
Technical field
The present invention relates to metallurgical technology fields, and in particular to germanic organic matter produces germanium tetrachloride new process.
Background technique
Germanium is a kind of important rare and scatter element, wide with the development of science and technology with the raising of living standards of the people It is general to apply in people's lives and industrial and agricultural production.Germanium is mainly used for making optical fiber, catalyst and infra-red material, and nearly 30 years Come, germanium increasingly becomes the backing material of certain new and high technologies, germanium be intensively applied in high-tech area.It is shown in the Gulf War The power of germanium infra-red material, various countries mutually equip with arms oneself with high-tech unexpectedly, optical fiber germanium sustainable growth, produce as polyester fiber Catalyst germanium also increasing.Germanium occupies more and more important position in the national economic development and national defense construction, and germanium disappears Consumption can also be growing day by day, and germanium resource lacks on international market, supply falls short of demand.The separation and Extraction of germanium study oneself caused it is more and more Concern.
Summary of the invention
For the defects in the prior art, the present invention provides germanic organic matter and produces germanium tetrachloride new process.
Germanic organic matter produces germanium tetrachloride new process, includes the following steps:
The first step grinds germanic organic matter, then screening is prepared into pre- slurry, is delivered in flotation device and is floated Choosing, the material after flotation are dried, and obtain material dry powder;
Material dry powder is carried out the slow oxidation reaction of low temperature by second step;
Hydrochloric acid is added in third step, the material for taking second step to obtain thereto, then carries out low temperature distillation, obtains four chlorinations Germanium.
It in the present invention, as a kind of perferred technical scheme, in the first step, when grinding, is dry grinded using rod mill, when grinding Between be 15-20 minutes.
In the present invention, as a kind of perferred technical scheme, in the first step, when screening, sieved using 300 mesh hole wet types Point.
In the present invention, as a kind of perferred technical scheme, in the first step, it is prepared in pre- slurry, the weight of organic matter Amount percentage is 10-15wt%, remaining is flotation agent.
In the present invention, as a kind of perferred technical scheme, flotation agent is hydroximic acid, sodium alkyl hydroxamate, soya fatty acid The mixture of sulphation soap, oxidized paraffin wax soap.
In the present invention, as a kind of perferred technical scheme, hydroximic acid, sodium alkyl hydroxamate, soya fatty acid sulphation soap, The weight ratio of oxidized paraffin wax soap is 1:1:3:2.
In the present invention, as a kind of perferred technical scheme, in the first step, flotation device is using extension groove type floatation cell.
In the present invention, as a kind of perferred technical scheme, in the first step, screening uses Taylor's bushing screen.
In the present invention, as a kind of perferred technical scheme, in second step, material dry powder is laid in roasting ware, so It is placed in Muffle furnace, closed fire door, furnace temperature is gradually warmed up from room temperature to 500-525 DEG C through 30-45min, and at this temperature Then heat preservation 3-4 hours is warming up to 550-600 DEG C again, maintain temperature 2-3 hours.
In the present invention, as a kind of perferred technical scheme, in second step, it is 1:1 that weight ratio is mixed in material dry powder MnO2.
In the present invention, as a kind of perferred technical scheme, in third step, the material that second step is obtained is added three necks and burns In bottle, hydrochloric acid leaching germanium is added thereto, during hydrochloric acid leaching, each mouth of three-neck flask will jump a queue closed, wave to prevent hydrochloric acid Hair, extraction time are 2-3 hours;Concentration of hydrochloric acid in test solution is adjusted to 8-9mol/L and heats distillation;Utilize air setting Still keeps temperature to be condensed back to 105-107 DEG C,
In the present invention, as a kind of perferred technical scheme, in third step, before heating, boron is added into three-neck flask Acid and MnO2.
Due to using the technology described above, the invention has the following beneficial effects:
The first step of the invention using hydroximic acid, sodium alkyl hydroxamate, soya fatty acid sulphation soap, oxidized paraffin wax soap it is mixed It closes object and carries out flotation, can remove most of impurity, reduce and extract germanium feed material directly from organic matter, to reduce hydrochloric acid Dosage reduces cost;Meanwhile special flotation agent is that inventor obtains by long-term practice, which has fraction heavy, close Degree is high, viscosity is big, and the oil droplet size dispersed in water is big, and the features such as the speed of organic matter unfolded surface is slow, but hydrophobicity is strong, The quantity absorbed by organic matter surface pore is few, greatly improves the efficiency of flotation, is that the extraction of subsequent germanium tetrachloride is created Good condition is made.
Because Ge O after temperature is higher than 350 DEG C, starts to aoxidize and form Ge O2;At 260 DEG C oxygen just occurs for Ge S2 Change and generates Ge O2;Ge S starts to aoxidize and form Ge SO4 at 350 DEG C, when temperature is higher than 350 DEG C, oxidation product Maximum possible is to form Ge O2;But if temperature is excessively high, and germanium is easy to exist with the solid solution of Ge O2-Si O2 in coal, the solid solution Form is difficult to by Ore Leaching.Therefore, the mode slowly to heat up is taken in second step of the present invention, while manganese dioxide is added, metal Germanium can be stayed in calcining matter by manganese dioxide, while the organic carbon in organic matter being removed, and be conducive to further chlorination leaching It handles out.
In third step of the invention, due to using method of the invention, germanium, which basically forms, in the step is soluble in acid Ge O2 form, when salt Ore Leaching, Ge O2 is easier to occur with reacting for HCl, so directly salt Ore Leaching at normal temperatures and pressures Germanium;Germanium is leached under normal temperature and pressure, energy consumption needed for not only having saved heating, but also the equipment anticorrosion solved under the conditions of high temperature concentrated acid are asked Topic, so that the process flow of salt Ore Leaching distillation can also be simplified.
In conclusion present invention process process is simple, the output capacity of germanium tetrachloride in organic matter is improved.
