Description

From solution containing nickel, remove the method for impurity copper
Technical field
The present invention relates to the extraction metallurgy in hydrometallurgy field, particularly nickel, is a kind of method of removing impurity copper from solution containing nickel.
Background technology
Copper nickel is similar element, in the nickel minerals all association metallic copper is arranged.Nickel/copper is separated into an important step in the nickel smelting process.
The nickel ore concentrate of present industrial employing adds anode sludge method, is after the nickel electrowinning deironing in the liquid, and the nickel ore concentrate and the anode sludge that added proportioning and be 4: 1 carry out copper removal.Though this method itself is not very complicated, have the nickel of benefit function, copper removal after the liquid cupric still can reach requirement, labour intensity is big, reagent dosage is high, behind the copper removal in the liquid iron level also go up to some extent.And electric nickel per ton will produce the about 150kg of copper ashes, and contains in the slag about Cu20%, and is nickeliferous then up to Ni40%, not treatment process preferably.Have to adopt the full soaking technology of chlorine to handle, to reclaim nickel in the slag.After the processing, metals such as the nickel in the copper ashes, copper substantially all enter leach liquor, have increased the processing pressure of subsequent handling.Copper is removed from electrolysis system with the form of negative electrode copper sponge by the liquid making operation.Copper recovery descends, cost increases owing to toss about in bed to cause repeatedly in system.Chlorine leaches in the copper ashes and also contains more precious metal, does not have suitable technology to recycle, and stacks in the slag field always.
For replacing this method, Chinese patent 94107298.3 has been studied the active nickel sulfide method, by this method, nickel anode liquid after the deironing and sodium sulphite is reacted under specific temperature, pH and concentration conditions obtain so-called active nickel sulfide.When being used for copper removal, at first to the reduction of the cupric ion in the solution be become cuprous ion, add active nickel sulfide again, in reaction more than 60 ℃ with S-WAT or sulfurous gas.The concentration of copper can be dropped to below the 2mg/1, the copper nickel mass ratio that removes copper ashes after the press filtration is about about 20: 1, can be used as copper ore concentrates and directly send the copper melting.
Jinchuan company had once carried out commerical test in 1998 with regard to the active nickel sulfide method.But the deficiency of this method be following some: at first be the activity problems of nickelous sulfide, for guaranteeing its activity, require comparatively strict synthesis condition.Temperature will be below 30 ℃, because synthetic acidity have a strong impact on the copper removal index, pH need be controlled at 8.5-9.0, even stirring velocity descends to some extent and will cause specific surface area to descend and the remarkably influenced activity by a relatively large margin.Wang Fei dysprosium etc. points out that in " research of nickel sulphide precipitation conversion method deep purifying copper removal from nickel electrolyte " of Hunan metallurgy (1993,5 phase) it is too short that the activity of nickelous sulfide is held time, just for one day even a few hours; Secondly, to influence the nickelous sulfide activity in order not delaying, can not to carry out liquid-solid separation after synthesizing, have to directly treat the nickel sulfate solution of copper removal with the form adding of ore pulp.But so,, also cause stoichiometry difficulty (having to measure indirectly in the test like this) by the system CONTROLLED POTENTIAL not only with the sodium drawing-in system; Once more, the pH during owing to preparation has a strong impact on the activity of nickelous sulfide, needs precision monitor.But be used to measure the glass electrode surface easy deposition NiS of pH and measuring error strengthened and serious hysteresis, its use and maintenance complexity.Wang Minxue is at nonferrous metallurgy design and research 2003,24 (increasing), point out in the application of oxidation-reduction potentiometer in hydrometallurgy that the potentiometer that is used to monitor current potential during copper removal also needs often to demarcate to guarantee that accurately its installation site is also bigger to measuring influence; At last owing to prepare operation height correlation, interlocks such as active nickel sulfide, sulphur dioxide reduction cupric ion, nickelous sulfide copper removal in the whole process, to the online detection of compactedness, the continuity of operation, data and automatically control require high.
Jinchuan Nonferrous Metal Co. has finally still abandoned the active nickel sulfide method.To except that reverting to traditional nickel ore concentrate again, copper process add the anode sludge in the clean liquid process except that process for copper.
Summary of the invention
The purpose of this invention is to provide a kind of new decoppering agent and copper-removing method, be used for removing impurity copper from the solution containing nickel degree of depth.Have the active height of decoppering agent, length of active hold-time, do not introduce harmful ion; Remove nickeliferous low, copper/nickel ratio height in the copper ashes; Advantage simple to operate.
Adopt solid-state thiocarbonic acid SOH nickel to make decoppering agent, so-called thiocarbonic acid SOH nickel decoppering agent is NiCS 3, NiC 2S 5, NiC 3S 7... NiC nS 2n+1Among one or more compounds, also can contain NiS.
During copper removal, add thiocarbonic acid SOH nickel in solution containing nickel, and to make the molar ratio range of copper contained in nickel contained in the thiocarbonic acid SOH nickel and the solution be 1.0-2.0, preferred value is 1.2-1.8; Control solution temperature scope is 10-150 ℃, and preferred value is 50-80 ℃; The pH scope is 2-7, and preferred value is 3-5; The copper removal time is 5-300 minute, and preferred value is to carry out under 20-100 minute the condition.
After copper removal finished, filtering separation was removed copper ashes and solution.
The thiocarbonic acid SOH nickel decoppering agent that the present invention adopts has the long-term advantage that keeps of agent of activity.And the copper removal process is simple, does not introduce harmful ion.But degree of depth copper removal and remove copper/nickel mass ratio height in the copper ashes.Environmental friendliness of the present invention.
Be described further below in conjunction with example.
