It is further preferred that second equipment for separating liquid from solid is solid-liquid separating machine.
Preferably, the entrance of the silver recovery unit connects with sodium carbonate liquor feed arrangement and Cymag feed arrangement respectively
Connect, its outlet is connected with the 3rd equipment for separating liquid from solid.
It is further preferred that the 3rd equipment for separating liquid from solid is solid-liquid separating machine.
It is further preferred that the liquid outlet and solid outlet of the 3rd equipment for separating liquid from solid, respectively with filter press and
The silver-colored reaction unit connection of zinc displacement.
Method of work of the present utility model, including step：
(1) pre-process：Lead melting waste slag is cooled to 0~5 DEG C, is then warming up to 500~600 with the speed of 10 DEG C/min
℃；
(2) alkali leaching：Lead melting waste slag is mixed with sodium hydroxide solution while hot, obtains alkali immersion liquid and alkali phase analysis；
(3) the heavy lead of alkali immersion liquid vulcanization：To sodium sulfide solution is added in step (2) gained alkali immersion liquid, until in alkali immersion liquid
Lead is all precipitated, and obtains lead concentrate；
(4) sized mixing to being added water in step (2) gained alkali phase analysis, add sodium carbonate liquor and adjust pH value to 10~11, so
Adding Cymag afterwards carries out Cyanide Leaching, obtains leachate and leached mud, and leached mud press filtration is stored up, and leachate is by purifying, taking off
Oxygen, zinc dust precipitation treatment, obtain silver-colored mud.
Lead melting waste slag and the mass volume ratio of sodium hydroxide solution are 1 in step (2)：2~4, sodium hydroxide solution
Mass concentration is 20%.
The mass concentration of sodium sulfide solution is 15~20% in step (3).
The alkali phase analysis after sizing mixing that added water in step (4) account for the 25~30% of gross mass.
The mass concentration of sodium carbonate liquor is 18% in step (4).
Cyaniding sodium content is the 0.15~0.2% of total leachate quality in the leachate obtained in step (4).
The time of Cyanide Leaching is 24~36 hours in step (4).
The beneficial effects of the utility model：
The pretreatment that lead melting waste slag first lower the temperature plus be rapidly heated by the utility model, improves the internal junction of waste residue
Structure so that metallic element is easier to be discharged.Then alkali leaching treatment is carried out while hot, and the immersion liquid of gained alkali and alkali phase analysis are distinguished
Enter quadrat to reclaim and silver recovery treatment, the utility model simple structure, realize the high efficiente callback enrichment of lead and silver.
After testing, the utility model gained lead concentrate in lead mass content more than 60%, silver the rate of recovery 95%
More than.
