Description
Technical field
The present invention relates to a kind of processing method that contains cobalt nickel waste material, old and useless battery treatment.
Background technology
As everyone knows, old and useless battery and deleterious cured article are sneaked in the domestic refuse usually, and treatment process mainly is sanitary landfill, compost and three kinds of methods of burning, and the deficiency of landfill is polluted source and soil, particularly contain heavy metal in the battery, heavier by transudation to water source and soil pollution.The method that adopts heap to bury is handled the downgrade that makes compost again.Incinerating method is to adopt incinerator to burn, incinerator is made up of cylindrical furnace and chimney, body of heater is provided with dog-house, ash removing hole, the deficiency of this method is an etching apparatus, heavy metal in the old and useless battery volatilizees in flying dust in incinerator, cause great gas to pollute, the accumulation of incinerator furnace bottom heavy metal makes the lime-ash of generation form new source of pollution, and the reflection of employing stove fire metallurgy method is also arranged now, though this method can be carried out recycling, but the rate of recovery is low, and remaining lead is discharged with the form of gas and dust, causes secondary pollution, sulfurous gas in the while smelting process is polluted air also, and the healthy harm to the operator is bigger in addition.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, a kind of processing method that contains cobalt nickel waste material, old and useless battery treatment is provided, this method is simple, and is how pollution-free to ring.
The invention discloses a kind of processing method that contains cobalt nickel waste material, old and useless battery treatment, described treatment process comprises the steps:
1) broken apart containing after cobalt nickel waste material, the old and useless battery thermal treatment of reclaiming;
2) particle after broken apart is carried out ball milling, the molten thick solution of nickel cobalt that obtains of acid;
3) the thick solution of nickel cobalt obtains high-purity cobalt nickel solution and high-purity cobalt solution by chemical purification, purification by liquid extraction;
4) high-purity cobalt nickel solution and high-purity cobalt solution obtain rose vitriol and nickel sulfate hexahydrate crystal by crystallization;
5) synthetic nickel presoma and the cobalt precursor of obtaining of high-purity cobalt nickel solution and high-purity cobalt solution liquid phase;
6) the nickel presoma obtains the nickel powder body by high-temperature heat treatment;
7) cobalt precursor obtains the cobalt powder body by high-temperature heat treatment.
The further method of the present invention is: described step 3) also will obtain waste water, lithium solution, aluminum solutions, cadmium solution, nickel solution and Tongling solution.
The present invention further method is: the waste water of described step 3) by wastewater treatment after, the waste water slag is handled again, waste water returns use.
The further again method of the present invention is: the lithium solution of described step 3) leads to Quilonum Retard by deposition.
The further again method of the present invention is: described step 3) aluminum solutions obtains aluminium hydroxide by crystallization.
The further again method of the present invention is: the cadmium solution of described step 3) enters existing treatment scheme and handles.
The further again method of the present invention is: the nickel solution of described step 3) obtains electro deposited nickel by electrodeposition.
The further again method of the present invention is: the copper solutions of described step 3) obtains electro deposited copper by electrodeposition.
The further again method of the present invention is: the nickel powder body of described step 6) is the extra-fine nickel powder body.
The further again method of the present invention is: the cobalt powder body of described step 7) is the super-fine cobalt powder body.
A kind of beneficial effect that contains the processing method of cobalt nickel waste material, old and useless battery treatment of the present invention is: this method is the method for environmental protection treatment, and method is simple, and how pollution-free ring is, but refine goes out super-fine cobalt powder and extra-fine nickel powder, makes full use of waste material.
