Abstract
The present invention discloses a method for removing heavy metal ions from manganese sulfate solution. 0.1 to 300 g. L<-1> manganese metal powder is added in the manganese sulfate solution. The temperature of the solution is adjusted to 5 to 100 DEG C, the pH value is controlled between 2 to 14, and the manganese sulfate solution with the manganese metal powder is stirred for 0.2 to 5 hours and filtered to obtain the manganese sulfate solution. The method utilizes an oxidation reduction reaction principle, the reaction conditions are easy to control, the reaction effect is good, the cost is low, and other impurities are not introduced.
Description
Technical field
The present invention relates to a kind of method of removing heavy metal ion in the sulfuric acid manganese solution, belong to manganese ore leach liquor impurity separation technology field.
Background technology
The sulphuric leachate of pyrolusite or rhodochrosite contains various heavy metal ion, and especially the sulphuric leachate of pyrolusite contains more heavy metal ion, and heavy metal ion has Cu
2+, Co
2+, Ni
2+, pb
2+, Cd
2+, Zn
2+Deng.The method that the removing heavy metals ion is commonly used from manganese sulfate solution is a sulphide precipitation at present, in manganese sulfate solution, add vulcanizing agent exactly, the sulfide that utilizes vulcanizing agent and heavy metal ion to generate is insoluble in the character of water, heavy metal ion is precipitated the method for removing.Vulcanizing agent has organic sulfurizing agent (as SDD etc.) and inorganic sulphide agent (as barium sulphide, ammonium sulfide, sodium sulphite etc.).Sulfide method is to deposit C u
2+, Cd
2+, Ni
2+Plasma is comparatively effective, but to pb
2+, Co
2+, Zn
2+Isoionic removal effect is relatively poor.During in addition such as pyrolusite leach liquor removing heavy metals ion, higher because of concentration of heavy metal ion in the leach liquor, need to add a large amount of vulcanizing agents, cause a large amount of sulfide impurities to enter solution, cause to subsequent technique to have a strong impact on.It is to utilize the metal active of manganese metal than big advantages of metal such as Cu, Co, Ni, Pb, Cd that this law adopts manganese powder removing heavy metals ion, make reductive agent with manganese metal the metal ion of these metals is reduced to precipitated metal, and manganese metal itself is oxidized to Mn
2+, generation be manganous sulfate, to solution without any pollution.
Summary of the invention
In order to solve the problem of above-mentioned existence, the purpose of this invention is to provide a kind of method of utilizing redox principle to remove the heavy metal ion in the manganese sulfate solution.
