Abstract
The invention discloses a production method of novel electrolytic nickel and relates to the technical field of chemical production. The production method comprises the following steps of 1, electrolyzing a nickel-containing raw material by a sulfate electrolyte and then adding sulfuric acid into the electrolyte to adjust an electrolyte pH value to 3.0-5.5, and 2, making the electrolyte go through ion exchange resin and active carbon to remove impurities in the electrolyte, feeding the electrolyte into a high-position liquid storage tank, carrying out heating to a temperature of 55-80 DEG C, feeding the electrolyte into a diaphragm bag, and carrying out electrolysis for 24-36h to obtain the high-purity electrolytic nickel. The production method utilizes a recovered nickel product to realize re-production and has simple processes. The novel electrolytic nickel obtained by the production method has high purity, contains few impurities and can be well used for each industry.
Description
Technical field:
The present invention relates to chemical production technical field, be specifically related to a kind of production method of novel electrolytic nickel.
Background technology:
Nickel is a kind of argenteous metal, there is physical strength high, ductility is good, infusibility, the not oxidizable good characteristic that waits in air, therefore, it for the manufacture of stainless steel and various steel alloy be widely used in the fields such as machinofacture in the military industry such as aircraft, tank, guided missile and industry and electronic telecontrol, the manufacture method compared of existing general electrolytic nickel is complicated, and the electrolytic nickel purity of producing is not high.In the production process of high purity nickel, electrolytic solution must circulate and make
With.Nickel electrolyte purification impurity removal process mostly adopts following methods both at home and abroad at present, and deironing adopts neutralizing hydrolysis method, jarosite process and hematite process.Copper removal adopts cementation or extraction process.Except cobalt adopts neutralizing hydrolysis, extraction or " black nickel " oxidizing water solution.Deleading, zinc adopt coprecipitation method, ion exchange method and extraction process, but the percentage extraction of some impurity is still very low.
Summary of the invention:
The production method that the object of this invention is to provide a kind of novel electrolytic nickel, it adopts the nickel goods that reclaim to re-start production, and production method is simple, and the electrolytic nickel purity of producing is high, and impurity is few, and product can better be applied to industry-by-industry.
In order to solve the existing problem of background technology, the present invention takes following technical scheme: its production method is: (1) adopts vitriol physique electrolytic solution to carry out electrolysis nickel-bearing raw material, after electrolysis completes, adds sulfuric acid that the pH value of electrolytic solution is adjusted to 3.0-5.5; (2) then by electrolytic solution by ion exchange resin and gac by the Impurity removal in electrolytic solution, with pump, electrolytic solution is sent in high-order reservoir, heated to 55-80 ℃, electrolytic solution flows into and in diaphragm bag, carries out electrolysis, electrolysis time is 24-36 hour, obtains high purity electrolytic nickel.
Removal of impurities concrete steps in described step (2) are: at room temperature (25 ℃) carry out, and first adopt M5640 to remove cupric ion, make the content of cupric ion be less than 0.1mgL
-1, then adopt P1507 to remove foreign ion iron, zinc, lead removed; Finally with sodium hydroxide solution homogeneous phase soapmaking 75%, remove nickel ion, and measure pH value with pHS3D type pH, with each ion content of aas determination.
The present invention has following beneficial effect: it adopts the nickel goods that reclaim to re-start production, and production method is simple, and the electrolytic nickel purity of producing is high, and impurity is few, and product can better be applied to industry-by-industry.
