Description
The application is Application No. 201510839622.8, and the applying date is on November 27th, 2015, and invention and created name is
The divisional application of the application for a patent for invention of " with the method for cobalt and manganese in ammonia-ammonium hydrogen carbonate separation and recovery high manganese waste material of low cobalt ".
Technical field
The present invention relates to a kind of separation and recovery method of cobalt manganese waste material, and in particular to a kind of ammonia-ammonium hydrogen carbonate separates back
Receive the method for cobalt and manganese in the high manganese waste material of low cobalt.
Background technology
Containing substantial amounts of cobalt, manganese element in caused useless cobalt-manganese catalyst in PTA productions, wherein cobalt content is about 10 %,
Manganese content is about 20 %.Cobalt is a kind of important strategy metal, and its physics, chemical property are excellent, is production heat-resisting alloy, hard
Alloy, anti-corrosion alloy, the important source material of magnetic alloy and various cobalt salts；And China's cobalt ore resource famine, but the year of cobalt
Consumption figure increases year by year, and domestic cobalt resource can not meet productive consumption demand, and most of cobalt raw material relies on import.Manganese is a kind of
Transition metal, property is hard and crisp, and moist place can aoxidize, and the most important purposes of manganese is manufacture manganese alloy.
At present, both at home and abroad the method for conventional separation and recovery cobalt-manganese catalyst mainly have chemical precipitation method, solvent extraction,
Electrolysis and ion-exchange etc..Chemical precipitation method is easy to operate, technological process is simple, but easily equipment is caused to corrode,
Need to optimize.Solvent extraction can efficiently separate out cobalt, cheap, but organic solvent easily causes to endanger to environment
Evil, and the condition control reacted requires also higher.Electrolysis can reclaim to obtain the high electrolytic cobalt of purity, but with electricity
Solve the defects of liquid is unstable.Ion-exchange can reach rich product and the purpose of purification, storng-acid cation exchange resin tool simultaneously
There is the characteristics of absorption appearance is maximum, and adsorption rate is fast, but ion exchange resin needs regular regeneration, produces a large amount of alkaline waste waters,
Environment is polluted.
On chemical precipitation method, Chinese patent literature CN 1236735A（Application number 98111313.3）Disclose a kind of cobalt
The separation and refining method of Mn mixture, vulcanized sodium will be first added after compound acidolysis and is co-precipitated cobalt manganese, then passes through cobalt, manganese sulphur
The solubility product difference of compound first dissolves manganese, then the cobalt sulfide with mixed-acid dissolution indissoluble.This method can efficiently separate cobalt,
Manganese is simultaneously reclaimed, but acid dissolution consumes a large amount of acid solutions three times, and the discharge of acid solution can cause greatly to pollute to environment.
Chinese patent literature CN 1059241C（Application number 98111506.3）It is high from leftover bits and pieces containing cobalt to disclose one kind
The new technology of effect extraction cobalt/cobalt oxide, including acid is molten, ammonification separation plus alkali are heat sink, absorbs, separating, washing step；It is described to contain cobalt
Leftover bits and pieces includes cobalt, iron, manganese element；The molten processing of acid is leftover bits and pieces is preprocessed or be directly dissolved in sulfuric acid or hydrochloric acid, acid
