Description
The application is application No. is 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 methods of cobalt manganese waste material, and in particular to a kind of to be separated back with ammonia-ammonium hydrogen carbonate
The method for receiving cobalt and manganese in the high manganese waste material of low cobalt.
Background technique
Containing a large amount of cobalt, manganese element in the useless cobalt-manganese catalyst generated in PTA production, wherein cobalt content is about 10 %,
Manganese content is about 20 %.Cobalt is a kind of important strategy metal, and physics, chemical property are excellent, is production heat-resisting alloy, hard
The important source material of alloy, anti-corrosion alloy, magnetic alloy and various cobalt salts；And there is a serious shortage of but years of cobalt for China's cobalt ore resource
Consumption figure increases year by year, and domestic cobalt resource has been unable to 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.
Currently, both at home and abroad the method for common separation and recovery cobalt-manganese catalyst mainly have chemical precipitation method, solvent extraction,
Electrolysis method and ion-exchange etc..Chemical precipitation method is easy to operate, process flow is simple, but is easy to cause to corrode to equipment,
It needs to optimize.Solvent extraction can efficiently separate out cobalt, cheap, but organic solvent easily causes to endanger to environment
Evil, and the condition control requirement reacted is also relatively high.Electrolysis method can recycle to obtain the electrolytic cobalt of purity is high, but have electricity
Solve the unstable defect of liquid.Ion-exchange can achieve the purpose that rich product and purification, storng-acid cation exchange resin tool simultaneously
There is absorption to hold maximum, the fast feature of adsorption rate, but ion exchange resin needs regular regeneration, generates a large amount of alkaline waste waters,
It pollutes the environment.
About 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 will first be added vulcanized sodium and be co-precipitated cobalt manganese after mixture acidolysis, then pass 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 recycled, but acid dissolution consumes a large amount of acid solutions three times, and the discharge of acid solution can cause environment greatly to pollute.
Chinese patent literature CN 1059241C(application number 98111506.3) disclose one kind height from leftover bits and pieces containing cobalt
Effect extracts the new process of 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 that leftover bits and pieces is preprocessed or is directly dissolved in sulfuric acid or hydrochloric acid, sour
Solution ph is maintained at 2~3；Ammonification separation be by acid it is molten come clear mixed acid solution excessive ammonia is added, keep pH value 8~
9, iron and manganese are separated from reaction solution in this step in the form that hydroxide precipitates；Adding alkali heat sink is in cobalt ammonia complexing
Caustic soda is added in solution based on object to be heated to boiling, obtains cobalt oxide.Actual treatment cobalt manganese is useless according to the method described above by inventor
When material, it is found that the rate of recovery of cobalt is only 70%.
In addition, Chinese patent literature CN 104831065A(application number 201510164284.2) disclose a kind of high manganese cobalt
Than the method that nickel cobalt in nickel cobalt manganese raw material is separated with manganese, high manganese cobalt is directly mixed with ammonia leaching agent than nickel cobalt manganese raw material, is added
Enter reducing agent, separate solid-liquid after heat preservation ageing, so that nickel cobalt and manganese be separated.Although the leaching rate of this method cobalt can achieve
90%, and simple process, still, since manganese content is greater than 20% in the cobalt manganese slag that generates in PTA production, according to this straight
The method liquid-solid ratio for connecing ammonia leaching is too small, and cobalt is easy to be wrapped up by manganese, and the leaching rate of cobalt then will be greatly reduced.
