Abstract
A kind of zinc abstraction nickel cobalt slag recoverying and utilizing method, three sections of inverse antimony purification two-stage nitration purify the nickel cobalt slag produced and add one section of purification after pulp, utilizing the zinc powder of remaining in nickel cobalt slag to purify copper removal cadmium at one section, the slag after using forms copper cadmium cobalt residue, purifies no longer output nickel cobalt slag.Copper cadmium cobalt residue is reclaimed by cadmium after carrying out copper cadmium cobalt residue leaching separation copper, cadmium, and solution is containing between cobalt 150 1000mg/l, and after using organic reagent Call Provision, solution returns main system.The method can make full use of remaining zinc powder, reduction purification zinc consumption in nickel cobalt slag；The recovery of the dangerous solid waste nickel cobalt slag for producing in wet method zinc abstraction opens up a new way；Simplifying cadmium remanufacture technological process, production operation is simple, there is no precedent report both at home and abroad.
Description
Technical field
The invention belongs to zinc hydrometallurgy industry, for the dangerous solid waste of zinc hydrometallurgy Industrial Output--the recycling of nickel cobalt slag is opened
Having warded off a new approach, the method can make full use of the zinc powder of remaining in nickel cobalt slag, reduces one section and purifies zinc powder use
The purpose of amount, in turn simplify cadmium remanufacture technique, has saved production cost.
Background technology
In the neutral leaching process of zinc hydrometallurgy, the foreign metal major part such as Fe, As, Sb, Ge can be by neutralizing water
Solution preocess removes from solution, but the impurity such as Cu, Cd, Co, the Ni in solution cannot remove at neutral leaching stage, these impurity
Relatively big to Zinc electrolysis harm, before electrodeposition, have to pass through purification.Commonly used three sections of (inverse) antimonic salts of most enterprises are clean now
Change method, first low temperature is except Cu, Cd, then high temperature is imitated except Co, Ni, its good purification, product quality and electrodeposition electricity and all can be reached satisfied
Effect.Three sections of antimony trioxide purification method one two-stage nitration purify output copper-cadmium slag and two kinds of slags of nickel cobalt slag respectively.In industry generally by this two
Planting slag individual processing, copper-cadmium slag is after leaching, replace and separating copper cadmium, and solution of zinc sulfate returns main system after except cobalt；Nickel cobalt slag
Nickel cobalt slag is remained after pickling.Thus make the dangerous solid waste of zinc hydrometallurgy Industrial Output--nickel cobalt slag.Along with environmental requirement
Raising day by day, the process of dangerous solid waste, transport more and more difficult, many enterprises are forced to process self-produced dangerous solid waste voluntarily,
Reach the purpose that cleaning produces.The process of nickel cobalt slag, many enterprises self-built zinc sulfate production line of employing or cobalt remanufacture line
The problems such as mode recycles, and does not only exist one-time investment big, and production cost is high, often production marketing difficulty, obtain not
Repay mistake.
Summary of the invention
The purpose of the present invention is exactly that the dangerous solid waste for zinc hydrometallurgy Industrial Output--the recycling of nickel cobalt slag opens
Article one, new approach, makes comprehensive utilization, recovery nickel cobalt slag be possibly realized.
Zinc powder consumption is an important economic indicator in Zinc Hydrometallurgy Process, reduces zinc consumption, is also to reduce electricity
Zinc cost, the important channel increased economic efficiency.
According to zinc powder purification by arsenate except the thermodynamic argument of cobalt, Co2+/ Co current potential-0.277V, Cu2+/ Cu current potential+
0.344V、Zn2+/ Zn current potential-0.762V, when displacement is except cobalt, containing a small amount of antimony in solution, as except the activator of cobalt process,
Co can be effectively improved2+Deposition potential, and separate out Co Yu Sb be easily formed CoSb and CoSb2, reduce the precipitation supervoltage of Co, more
Be conducive to except Co.But zinc powder utilization rate is the lowest when zinc powder purification by arsenate removes cobalt, two-stage nitration high temperature need to add cobalt 200 times except nickel cobalt
Nickel cobalt could be removed to the requirement meeting Zinc electrolysis, containing the zinc that a large amount of unreacteds are complete in the nickel cobalt slag of output by above zinc powder
Powder.For these years, the effort through several generations technical staff does not the most solve this problem, causes zinc hydrometallurgy zinc powder consumption always
High, production cost is higher.
Through chemical examination, fresh two-stage nitration nickel cobalt slag metal-containing zinc is up to more than 35% (chemical examination composition is shown in Table 1).Through testing
Card, this portion of residual zinc powder may be used for one section of purification replacement zinc powder and carries out the displacement reaction of copper removal cadmium, thus reaches nickel cobalt slag
The purpose recycled and reclaim, and other operating conditions are the most constant.
The nickel cobalt slag result of laboratory test (unit: %) that table 1 is fresh

Detailed description of the invention
A kind of zinc abstraction nickel cobalt slag recoverying and utilizing method, returns one section including purifying Ni and Co slag and purifies as zinc powder recycling,
Cadmium reclaims cancels nickel cobalt slag pickling production, reclaims the cobalt-carrying solution after copper cadmium and uses three parts such as organic reagent Technology for removing cobalt.
The method is a new approach of the recycling of nickel cobalt slag, can effectively reduce purification zinc consumption.
1, the method first using send cadmium to reclaim after oleo stock to carry out the two-stage nitration nickel cobalt slag of pickling change deliver to one section purify as
Zinc powder uses, and one section purifies minimizing zinc powder consumption more than 70%, and other control process conditions and do not change, it may be assumed that reaction temperature
50-90 DEG C, response time 1 3h, flow 100-160m3/ h, pH value 5.0-5.4.
2, after two-stage nitration nickel cobalt slag is used for one section of purification by step 1, purification one section of purification slag of an output, thus no longer output two
Section nickel cobalt slag, one section of purification slag is the mixing slag (can be copper cadmium cobalt residue) of copper-cadmium slag and nickel cobalt slag.
3, after two-stage nitration nickel cobalt slag is used for one section of purification by step 1, cadmium reclaims cancels former nickel cobalt slag acid cleaning process.
4, step 1 two-stage nitration nickel cobalt slag is used for one section purify after, the copper cadmium cobalt residue of output send cadmium recovery process fully according to
Former technical operation flow produces, and copper-cadmium slag leaches, the technology condition of displacement production cadmium cake is constant, and last cobalt-carrying solution
(lean cadmium solution) uses organic reagent Technology for removing cobalt except cobalt.
5, organic reagent described in step 4 is that the specialty that certain enterprise produces removes cobalt nickel reagent, black liquor, proportion 1.05
1.1, consumption is 15 20 times of cobalt amount of metal.
6, organic reagent Technology for removing cobalt described in step 4, controls reaction temperature 50-80 DEG C, response time 0.5 1.5h, removes
Cobalt nickel reagent addition is 15 20 times of cobalt amount of metal.
7, step 6 reaction terminates cobalt concentrate 3-6% Han cobalt, the zinc 10-18% of rear output, can reclaim metal further
Cobalt.
The method uses over 2 years in Qian Xin enterprise of Jiangxi Province, and two-stage nitration nickel cobalt slag is able to all of and reclaims, this enterprise
No longer output danger solid waste--nickel cobalt slag.In the case of quantity-produced, it can be ensured that qualified rate of new solution more than 99%.Two-stage nitration is clean
Changing after nickel cobalt slag returns one section of purification and fully recycled the remaining Zn powder in nickel cobalt slag, one section of purification the most all need not list
Solely add zinc powder, one section of zinc powder consumption 60 80% can be saved.Cadmium reclaims the pickling operation no longer carrying out nickel cobalt slag, annual output
100-150 ton cobalt concentrate, becomes new profit growth point.
