Description
Technical field
The present invention relates to metal purification technical fields, separate from cobalt, manganese carbonate mixture in particular to one kind
The method of cobalt.
Background technique
Cobalt is a kind of considerable national defense construction strategic materials, be widely used in space flight, aviation, electronics, battery,
The high-tech areas such as magnetic metal material.Content of the cobalt in the earth's crust is only 0.0012%, is belonged to than sparser metal, and
In nature, cobalt is coexisted with metallic elements such as manganese, nickel mostly.Since chemical property is similar, pole is brought to separating-purifying
The earth is difficult.
Existing cobalt, manganese isolation technics mainly have following three kinds: 1) hydroxide precipitation method: the separation of cobalt from manganese in hydrometallurgy
Crude separation is usually carried out using carbonate precipitation method, then carries out extracting and refining.This method higher cost, complex process, and
The final rate of recovery of cobalt only has 92%~94% or so, and a large amount of cobalt resources are wasted.2) manganese oxidation-precipitation method: is made by oxidant
With MnO2Form precipitating, so that it be separated with cobalt;Usually with ozone, chloric acid, SO2/O2Mixture is that oxidant carries out instead
It answers, but due to Co3+Become Co2+Normal potential be 1.8V, and Mn4+Become Mn2+Normal potential be 1.23V, the electricity of the two
Potential difference is larger, only controls oxidizer and pH value appropriate, can just make Mn2+Preferential Co2+Oxidation generates MnO2Precipitating.
3) solvent extraction: since above-mentioned two classes method separating effect is poor, also there is the technology for recycling extractant to be refined,
But higher cost has implemented certain difficulty.
Wherein, hydroxide precipitation method is mainly that the difference for the hydroxide solubility product that cobalt and manganese is utilized carries out selecting to sink
It forms sediment, Mn (OH)2: 19 × 10-13;Co(OH)2:1.6×10-15Cobalt is precipitated prior to manganese salt.It is single but since the two solubility product is close
One can not be thoroughly by separation of cobalt from manganese using hydroxide, Co (OH) that precipitation reaction obtains2In often contain more manganese.And it is sharp
With joint ammonia process, manganese is precipitated in the form of manganese carbonate, and cobalt then stays in the solution due to forming ammino-complex, though this method can carry out depth
Degree separation, but complex process, higher cost are unfavorable for production application.
To sum up, in prior art technology, energy consumption is high, yield is low for the purification of cobalt, and there is also environmental issues for some, greatly
Making full use of for resource is affected, causes much to waste.
Summary of the invention
