Description
Technical Field
The invention belongs to the technical field of nonferrous metallurgy, and relates to a nickel anode scrap treatment method.
Background
In the electrolytic nickel production process by diaphragm electrolysis, a high-sulfonium anode plate generates a nickel anode scrap after electrolysis, and the nickel anode scrap is required to be subjected to early nickel-copper separation due to the copper lug wire. And (3) removing anode slime from the separated nickel anode scrap blocks, returning to a casting system, pouring a high sulfonium anode plate for secondary recycling, and selling copper lug wires. The method for processing the nickel anode scrap in the prior art comprises the steps of firstly manually sorting out the nickel anode scrap with copper lug wires, and beating the nickel anode scrap by a hand hammer to break the nickel anode scrap, so that the copper lug wires are stripped from the nickel anode scrap to realize nickel-copper separation, wherein the breaking rate of the nickel anode scrap in the process is less than 60 percent, the sizes of the blocks are greatly different, and the nickel-copper separation is incomplete. The nickel anode scrap from which the copper lug wires are stripped is manually screened, so that the nickel anode scrap blocks and anode slime are separated, and the anode slime screening rate is less than 50%. Therefore, the manual operation process has the problems of more occupied labor resources, high simple and heavy labor intensity, poor crushing effect, incomplete manual crushing and screening, low labor efficiency, high production cost, easy splashing injury accident on the production site, high site potential safety hazard and the like. Wherein, the problem of poor crushing effect can cause the problem of difficult feeding of the reflective furnace mouth when the nickel anode scrap block with larger block diameter returns to the casting system for reuse, and cause disturbance to normal production; the anode slime is incompletely screened, so that the nickel anode scrap returns to contain higher sulfur, the sulfur dioxide smoke volume of the reverberatory furnace is increased, the smoke trapping treatment cost is increased, the environmental protection pressure is increased, and the requirements of high-quality green development cannot be met. The foreign nickel company adopts anode slime screening, then directly breaks the exposed copper lug wire of the nickel anode scrap, and the nickel anode scrap enters the copper of the pressurized leaching solution along with the nickel anode scrap block by a method of crushing, fine grinding and pressurized leaching, and is subjected to subsequent copper removal process treatment, so that the process flow is long.
Disclosure of Invention
The invention aims to solve the problems of poor crushing effect of the nickel anode scrap, low anode slime screening rate and long process flow in the existing nickel anode scrap treatment process, and provides a novel nickel anode scrap treatment method.
The technical scheme adopted by the invention is as follows: the nickel anode scrap treatment method specifically comprises the following steps:
(1) Drying the nickel anode scrap until the anode slime water content on the surface of the nickel anode scrap is 8-12wt%, and then sieving for the first time to remove the anode slime to obtain anode slime and a nickel anode scrap block, and conveying the anode slime to an anode slime stock bin for storage;
(2) Coarsely crushing the nickel anode scrap block in the step (1) until the granularity is less than or equal to 150mm so as to strip out part of copper lug wires, and finely crushing until the granularity is less than or equal to 35mm so as to thoroughly strip out the copper lug wires in the nickel anode scrap;
(3) And (3) carrying out secondary screening on the copper lug wire and the nickel residual electrode block stripped in the step (2), sorting out the copper lug wire, conveying the copper lug wire to a copper lug wire bin for stacking, and returning the nickel residual electrode of the sorted copper lug wire to a casting system for casting the high-sulfonium anode plate.
As the technical scheme of the invention is preferable, the drying process is carried out under the condition of continuous quantitative feeding, so that the single treatment material quantity can be kept constant, and the nickel anode scrap treatment effect is ensured.
The drying temperature is 70-120 ℃ and the drying time is 4-10h. If the drying temperature is too low (less than 70 ℃) or the drying time is too short (less than 4 hours), the anode slime attached to the surface of the nickel anode scrap is too little in water loss, the anode slime is strong in viscosity and adhesive force, the anode slime is not easy to fall off during screening, and the screen is easy to be blocked due to high water content of the anode slime, so that the screening effect and quality of the anode slime are affected; if the drying temperature is too high (more than 120 ℃) or the drying time is too long (more than 10 hours), the anode slime is too dehydrated, and spontaneous combustion of the anode slime is easily caused in the drying process, and even safety production accidents are caused.
The single sieve pore area of the sieve is 100-400mm when the primary sieve is used 2 . If the sieve pore area is too small (less than 100 mm) 2 ) The anode mud is easy to adhere to and block the screen mesh, so that the screening effect is affected; if the sieve mesh area is too large (> 400 mm) 2 ) The method is favorable for sieving anode slime, but is easy to cause loss of broken small nickel anode scrap blocks, increases the residual quantity of nickel carried by the anode slime, and reduces the direct nickel yield. More preferably, the mesh of the screen is round or square when screened once. In principle, only a single sieve opening area of 100-400mm 2 The effect of removing anode slime can be achieved, but compared with round or square sieve holes, rectangular and diamond sieve holes are longer in single side, small broken nickel anode scrap blocks have strong trafficability and low nickel direct yield under the same sieve hole area.
The secondary screening was carried out under continuous vibration conditions, and the mesh size of the screen was 30×30mm. According to the granularity of the finely crushed nickel anode scrap blocks (less than or equal to 35 mm), if the sieve opening of the sieve is too small (less than 30mm in specification), the nickel anode scrap is not thoroughly sieved, the phenomenon that the copper lug lines carry the nickel anode scrap blocks occurs, and the nickel direct yield is reduced; if the screen mesh is too large (larger than 30mm in specification), individual copper lug wires directly enter the nickel anode scrap block, and the phenomenon that the nickel anode scrap block carries copper lug wires occurs, so that the post production index is directly affected.
Compared with the existing nickel anode scrap treatment method, the method has the beneficial effects that:
1. the method can reduce the water content of the anode slime on the surface of the anode slime to 8-12wt% through a drying procedure, reduces the adhesive force of the anode slime on the surface of the anode slime, is favorable for removing the anode slime, and can prevent spontaneous combustion of the anode slime; through primary screening, the turnover and mutual friction of the nickel anode scrap are promoted, the thorough separation of the nickel anode scrap and anode slime is realized, the anode slime screening rate is improved to be more than 95%, the anode slime carrying rate of nickel anode scrap returning is less than or equal to 10wt%, meanwhile, the sulfur content of nickel anode scrap returning is reduced, the sulfur dioxide smoke quantity generated during the later-stage pyrogenic process is effectively reduced, and the flue gas treatment cost and environmental protection pressure are reduced.
2. The method reduces the diameter of the larger nickel anode scrap block by coarse crushing, and strips out part of copper lug wires; the particle size of the nickel anode scrap block is smaller through fine crushing and is relatively consistent, so that the nickel anode scrap and copper lug wires are thoroughly stripped; through secondary screening, the copper lug wires are separated from the nickel anode scrap blocks as oversize materials, the nickel anode scrap blocks are output outwards as undersize materials, the nickel anode scrap crushing effect is good, nickel and copper are completely separated, the nickel direct yield is high, the copper lug wire separation rate is more than or equal to 98%, and the copper-containing index of the nickel anode scrap blocks is reduced.
3. The invention can finish the treatment process of the nickel anode scrap through the procedures of drying, primary screening, coarse crushing, fine crushing and secondary screening, and has short process flow and low treatment cost.
