Abstract
The invention relates to a complexing germanium depositing agent used for enriching rear metal germanium, which uses natural gallnut flowers and Chinese chestnut bracts as the mixed raw materials. After the raw materials are smashed, deionized water is added for extracting tannin liquid, then the complexing agent ammonium chloride or ethylene diamine tetraacetic acid(EDTA) diamine and powdered activated carbon are added for reaction at the temperature of 50-70 DEG C with stirring, then the activated carbon is filtered out, and the filter liquid is evaporated and dried in vacuum mode to obtain powdered complexing germanium depositing agent. The complexing germanium depositing agent is added in germanium-containing ore solution and can lead germanium to generate complex fast in acidity condition so as to generate and deposit out polydentate chelate with a complex structure, and germanium depositing rate can reach 99%, and germanium concentrate with germanium concentration 15% larger than before can be generated.
Description
Technical field
The present invention relates to for the heavy germanium agent of a kind of complexing of enrichment rare metal germanium and in the application of germanic ore deposit liquid enriched germanium.
Background technology
Germanium is a kind of rare metal, with fields such as electronic industry, infrared optics equipment, photoconductive fiber, medical science, metallurgy, the energy, has a wide range of applications, and has become a kind of very important strategic resource.Germanium is typical dispersed elements, and the enrichment extractive technique is most important.Element Ge obtains mostly from germanic higher nonferrous metals ore, reclaim simultaneously the enriched substance of germanium in the smelting non-ferrous metal process.For example in zinc hydrometallurgy is produced, while processing the zinc sulfide concentrates of germanic higher (germanic 100-150g/ ton), at first germanium is enriched in leached mud, with fuming furnace, processes, in flue dust germanic 0.1%, use Ore Leaching, add the heavy germanium of Chinese gallotanninic acid after solution purification, germanic 3-5% in throw out, in the germanium ash that drying, calcining obtain, germanium is enriched to 15-20%, use this as germanium concentrate, further extract.
Along with expanding economy, the increase of the demand of germanium, resource and output as the Chinese gallotanninic acid of the heavy germanium agent of typical case can not be met the need of market far away, just there is the demand of nearly 3000 tons in domestic only southwestern market, cause the price of Weibull to be doubled and redoubled, thereby improved the extraction cost of germanium metal.
Summary of the invention
The object of the invention is to prepare the heavy germanium agent of a kind of complexing, improve the extraction yield of germanium, reduce the manufacturing cost of heavy germanium agent.
The germanium agent is sunk in complexing of the present invention, by following methods, is made:
The raw material dry product is doubly mixed and pulverizes in luxuriant 1:0.2~0.3 by weight of colored and dry product Chinese chestnut, after add deionized water to soak 2h, filter cleaner, get filtrate (be and mix tannin liquid), adds complexing agent ammonium chloride or EDTA diamines, add powdered carbon, 50 ~ 70 ℃ of lower stirring reactions at least 30 minutes, the filtering gac, filtrate is through vacuum-evaporation, drying, obtain meal, be the heavy germanium agent of complexing.
Described complexing dosage is the 1%-2% of times flower and Chinese chestnut bud material quantity.
Described deionized water soaking temperature is 50~70 ℃.
The application of the heavy germanium agent enriched germanium in the liquid of germanic ore deposit of described complexing, the method for enriched germanium is as follows:
15~25 times of amounts by germanium weight in the liquid of ore deposit drop into the heavy germanium agent of complexing, regulate pH to 2~3,35~45 ℃ lower stirring reaction,, until precipitation is separated out fully, filter to obtain throw out, and 450~500 ℃ of roasting 2h are cooling, obtain germanium concentrate.
The present invention uses the title complex generation method of coordination chemistry, adds the chemical complexing agent and make the compound tannin of proportioning uniqueness as heavy germanium agent in natural tannin extract.The heavy germanium agent of this complexing adds in the liquid of germanic ore deposit, can with metal ion germanium (central ion), complex compound occur under acidic conditions, and gradual reaction generates multiple tooth inner complex and be precipitated out rapidly, and heavy germanium rate reaches 99.0%, and throw out obtains germanium concentrate by roasting.Substitute Chinese gallotanninic acid with this heavy germanium agent and add in the ore deposit liquid of zinc metallurgy, when obtaining qualified zinc carbonate product, can obtain germanic amount greater than 15% germanium concentrate.Prepare this heavy germanium agent take the wildwood product doubly flower, Chinese chestnut is luxuriant as raw material, aboundresources, low price, can reduce heavy germanium agent production cost, economic benefits greatly.
