Acid-soaked cadmium-selenium contained acid pickle direct recycling method
The invention discloses an acid-soaked cadmium-selenium contained acid pickle direct recycling method. Acid-soaked cadmium-selenium contained acid pickle is directly used for preparing and producing a zirconium silicate microcrystal wrapped cadmium selenide pigment after being subjected to comprehensive treatment by use of a chemical reaction method. Zirconium oxychloride, sodium hydroxide and sodium sulfide are used for performing treatment on the acid-soaked cadmium-selenium contained acid pickle; after the zirconium oxychloride is added into the acid-soaked cadmium-selenium contained acid pickle, and the sodium hydroxide and the sodium sulfide are prepared to be a mixed solution by the addition of water according to needs, after a stirring synthetic reaction, filter pressing and washing are performed, drying is performed, then the obtained mixture is mixed with a mineralizer, white carbon black and selenium powder to be uniform, then high-temperature calcination is performed, the calcined product is subjected to the working procedures including acidification, ball-milling, filer pressing, washing, soda boiling, filer pressing and washing, and the zirconium silicate microcrystal wrapped cadmium selenide pigment product is obtained after drying.
